European projects
The laboratory of adsorption and catalysis is involved in several european projects:
Project FOTON
As a society, we currently face two major challenges: securing our future energy supply by transferring from fossil fuels to sustainable energy sources and reducing emissions of the greenhouse gas CO2. Only in this way can we achieve the objectives of the Paris climate agreement; limiting global warming to a maximum of 1.5°C in the 21st century and achieving net zero CO2 emissions by 2050. The FOTON project addresses both challenges.
In the INTERREG project FOTON, 9 project partners have the ambition to develop high-tech systems and materials for sunlight-driven sustainable processes that contribute to a climate-neutral industry. The direct use of sunlight as an energy source for chemical processes has a number of advantages compared to the conventional use of sustainably generated electricity. First, the high energy efficiency when using sunlight directly: there is no energy loss when converting sunlight into electricity, or less energy loss if the electricity is generated in the chemical reactor itself. Transport of electricity is not necessary and direct use is made of sunlight for the local production of green hydrogen and methanol. This decentralized production prevents high costs associated with infrastructure.
Three pilot demonstrators show that sunlight can be used as a sustainable energy source for the production of green methanol and green hydrogen in a technologically efficient, energy-efficient and financially feasible way.
The research within FOTON forms the basis for the future translation into an industrial process and offers commercial opportunities for manufacturers of materials and equipment and chemical companies in the region.

CO2PERATE
Flemish knowledge institutions join forces for research on Carbon Capture and Utilization: approval of CATCO2RE and CO2PERATE projects
Two research projects focusing on the discovery of new technologies to transform waste CO2 into value-added chemicals have been funded by the Flemish Government. The CATCO2RE project (2.5 million euro) is funded by the Research Foundation Flanders (FWO). The CO2PERATE project (2.6 million euro) is funded by the Agentschap Innoveren en Ondernemen (VLAIO), and supported by Catalisti, the spearhead cluster for chemistry and plastics. This support represents a significant milestone for the development of state-of-the-art expertise in CO2 capture and utilization in Flanders, and is expected to help address the impact of human activities on the environment. Both projects gather a multidisciplinary team of scientists from several Flemish institutions. CATCO2RE is a joint venture between UGent, KULeuven, VUB and VITO, while CO2PERATE is a collaboration between UGent, UAntwerp, KULeuven, VITO, and the Bio Base Europa Pilot Plant. Both projects are coordinated by Ghent University.
Turning waste into a resource
The discovery of efficient technologies that enable the use of CO2 as a starting material for chemical synthesis is one of the biggest scientific challenges of our time. It serves the dual purpose of reducing CO2 emissions and producing value added chemicals using CO2 as a building block, thus helping mitigate the effects of climate change while creating new opportunities for the chemical industry.
The specific target of CATCO2RE is to investigate the conversion of CO2 to methane and methanol using solar energy, integrating new developments in the production of solar hydrogen with catalyst design and state-of-the-art separation technologies, allowing for the integrated production of solar fuels. The integrated approach of CATCO2RE aims to significantly reduce operating and capital costs, making new CO2-to-methanol plants not only more economically competitive, but overall more sustainable. Meanwhile, CO2PERATE aims to develop catalytic technologies to convert CO2 into formic acid, using renewable electricity. Formic acid will subsequently be used as building block for the biosynthetic production of value added chemicals, as a building block for the chemical industry, or as a potential carrier for energy storage. The processes developed within CO2PERATE hence provide grid stability and integrate renewable electricity generation with the chemical industry.
With the launch of both research projects, the Flemish government provides a significant boost to establish a technology platform for catalytic CO2 reduction, focusing on all three potential routes for CO2 utilization: (i) CO2-neutral fuels and chemicals, (ii) CO2-based integration between renewable energy-production and chemical industry, and (iii) utilization of CO2 as a cost-effective C1 building block. To evaluate the potential of the different options, a decision support framework will be developed within CO2PERATE to select the best available technology for CO2 utilization within a given techno-economic context. The potentially new business models originating from CO2 utilization within CATCO2RE and CO2PERATE are expected to contribute significantly to economic and sustainable growth in Flanders’ circular economy.
PARTIAL-PGMs
PARTIAL-PGMs proposes an integrated approach for the development of smart and innovative nanostructured automotive post-treatment systems by integrating TWCs (Three-Way Catalysts) as part of the overall after-treatment system, namely the 1st generation of Gasoline Particulate Filters (GPFs), capable to meet future regulations, with reduced PGMs (Platinum Group Metals) and REEs (Rare Earth Elements), leading to the development of 2nd generation GPFs. The approach is broad and based on multiscale modeling, synthesis and nanomaterials’ characterization, catalytic performance determination as well as Life Cycle Assessment (LCA). The rational synthesis of nanomaterials to be used in these hybrid systems will allow for a reduction of more than 35% in PGMs and 20% in REEs content.
More information can be found on the Partial-PGMs website
NEXTGENCAT
The main objective of NEXTGENCAT proposal is the development of novel eco-friendly nano-structured automotive catalysts utilizing transition metal nanoparticles (Cu, Ni, Co Zn, Fe etc) that can partially or completely replace the PGMs. Based on nanotechnology, low cost nanoparticles will be incorporated into different substrates, including advanced ceramics (SiO2, perovskite etc) and silicon carbides, for the development of efficient and inexpensive catalysts. The main idea of the proposal is the effective dispersion and the controllable size of the metal nanoparticles into the substrate that will lead to improved performance.

Unlocking lithium's potential: dynamic flow-through lithium extraction from challenging aqueous environments with engineered 3D-shaped layered double hydroxide adsorbents.
Abstract
Lithium has risen as a critical raw material in many technological advancements, such as lithium-ion batteries. Nowadays, Li-recovery focusses on brine extraction via direct Li extraction (DLE), owing to its cost-effectiveness and environmental friendliness. The DLE efficiency is strongly dependent on the type of Li-selective adsorbent. Layered double hydroxides (LDHs) are most favored for industrial Li extraction due to their low costs, ease of fabrication and regeneration under neutral media. However, further developments are needed to increase the adsorption capacity and to increase the LDHs stability over multicycle use for prolonged operation. In this project, these challenges are tackled by smart engineering of LiAl-LDH at the atomic level (structure tuning) and at the macro level (3D shaping). We aim to achieve the best combination of Li adsorption features in terms of superior capacity, selectivity and long term stability. This will be done by engineering of the LDHs atomic structure via fine tuning of both layer and interlayer sites for precise anchoring of Li+ during DLE to prevent their deactivation. Further, to enable their continuous dynamic operation, the engineered LiAl-LDHs powders will be 3D-shaped with tuned surface and internal porosity to overcome diffusion limitations. The materials' efficiency for Li extraction will be evaluated in dynamic flow-through conditions.Researcher(s)

Marine Diesel Engine Exhaust Reduction (MADIENER).
Abstract
The International Maritime Organization (IMO) has set targets to reduce the greenhouse gas emissions in international shipping. Innovative solutions to convert exhaust gases in less harmful ones are highly needed. Therefore, this project focuses on the evaluation of exhaust gas treatment catalysts to abate Marine Diesel Engines emissions. The project specifically evaluates how the catalytic systems perform when operating the Marine Diesel Engines at different loads, in line with current practices to reduce fuel consumption as a part of emission control. In this project, Antwerp Maritime Academy (AMA), specialized in Marine Engine exhaust studies joins forces with the catalyst development groups of UAntwerp (LADCA and DuEL) to couple and develop Marine Diesel engine efficiency and exhaust abatement technology.Researcher(s)

Development of novel sorption materials for Ac-225/Bi-213 generators.
Abstract
Cancer remains one of the leading causes of death worldwide, requiring innovative methods for its treatment such as targeted alpha therapy with Bi-213 based radiopharmaceuticals. Alpha radiation is especially promising as it enables maximum destruction of malignant cells while minimizing cytotoxicity on the surrounding healthy tissue. Current challenges to separate the radioactive Bi-213 from the mother Ac-225 isotope prevent more widespread use in a clinical environment despite the promising results. Therefore, an innovative new sorbent material must enable a highly selective Ac- 225/Bi-213 separation, fast (de)-sorption kinetics, and a long operational lifetime. Moreover, the harsh separation conditions (exposure to highly acidic medium and high radiolytic dosages) limit the number of materials qualified for this application. In addition, these materials need to be shaped to an appropriate macroscopic architecture which allows sufficiently fast (de)-sorption kinetics. Therefore, the aim of this project is to develop a micron-sized shaped stationary phase with specific porosity and functional groups that promote the desired (de)-sorption kinetics, while adjusting chemical composition and structural features to provide optimal separation performance (selectivity and yield) in combination with radiation and acid stability. As such, this project aims to bridge the gap between materials synthesis and design.Researcher(s)

Developing radiation stable and selective surface interactions for direct Bi-213 generators.
Abstract
Effective cancer treatment strategies remain a global challenge. Targeted alpha therapy (TAT) with Bi-213 as alpha emitter radionuclide, bound to a targeting carrier molecule, has emerged as a promising approach, offering cytotoxic effects on cancer cells while minimizing damage to healthy tissue. However, the practical application is hindered by the lack of selective, radiation-stable and acid-stable sorbent materials to separate Bi-213 from its parent nuclide Ac-225, necessitating innovative approaches for improved 225Ac/213Bi separation materials (known as Bi-213 generators). This PhD project aims to develop sorbents with improved acid and radiation stability with enhanced selectivity to function as direct Bi-213 generators. The materials surface chemistry and synthesis-properties-performance correlation will be systematically investigated to optimize separation performance and stability, with a specific focus on enhancing selectivity without sacrificing stability. By addressing the challenges tied to Bi-213 generators, this research seeks to contribute to improved cancer treatment capabilities.Researcher(s)

Mapping and evaluation of carbon capture and utilization technologies for low-flow or low-concentration industrial CO2 emissions (Map-it CCU).
Abstract
The overall goal of the "Map-it CCU"-project is to centralize knowledge concerning the valorisation of industrial CO2 waste streams in a knowledge matrix and afterwards translate it (partly within and partly outside the Map-it CCU project) in a decision framework that can be used by companies with their technology choice. The following steps from the value chain will be taken up in the knowledge matrix: 1) Evaluation of existing and novel CO2 capture technologies in function of their applicability (e.g. CO2 concentration range and typical impurities); 2) Identification of purification- and conditioning steps to treat the captured stream to desired specifications. These depend on the destination of the stream. Within Map-it CCU delivery to a central CO2 pipeline and direct conversion to desired products are foreseen; 3) Conversion possibilities of purified and conditioned CO2 streams in end products (CCU, e.g. chemicals and fuels) or their final storage (e.g. CCS and mineralisation). In the decision framework we will search for differential parameters that allow companies to, given their specific situation, make a selection of technically feasible technologies. To this end, a couple of parameters that allow to take the specific situation of the company in question into consideration, will also be included, like the availability of local rest heat, available space, etc. The Map-it CCU project focuses in first instance on CO2 emitters and besides on companies that have an interest in CO2 conversion.Researcher(s)

Reductant free NOx abatement: catalyst development for direct decomposition.
Abstract
Direct decomposition is an excellent approach to reduce NOx exhaust gases, decreasing emissions in industry and providing a positive impact on climate change abatement. Nitrous oxide (N2O), also known as laughing gas, is characterized by a Global Warming Potential (GWP) 273 times that of CO2 over a 100 year's period, which clearly illustrates its impact on climate change. Moreover, problems such as premature death and financial impact on society clearly indicate the need for a reduction in its emissions. Using direct decomposition, the use of additional chemicals such as urea or ammonia is avoided during the decomposition of NOx to N2 and oxygen. Direct decomposition is an excellent option to achieve the abatement of NOx, but the following challenges should be solved before the catalysts are interesting for industrial settings: avoiding by-products, a low (hydro)thermal stability and poisoning by other gas components. Consequently, this project focuses on the development of innovative catalysts through an iterative synthesis-properties-performance development.Researcher(s)

Chemistry 2.0: Grignard surface modification unraveled
Abstract
Hybrid organic inorganic metal oxides combine the structural and physicochemical properties of inorganic materials with the versatility and specificity of organic molecules, creating exciting materials for a wide variety of applications in e.g. separation technology, catalysis, electronics and sensing. UAntwerp and VITO invented and patented a Grignard-based surface modification method anchoring the organic group directly to the metal oxide surface, which creates a unique synergic interaction between the metal oxide and the functional organic group, pioneering a new class of materials. While the applicability of this new method was well demonstrated in membrane filtration, the exact mechanism is still lacking. To allow broader and more specific steering of the materials properties this project is therefore aimed directly at 1) elucidating the mechanism of the surface modification; and 2) identifying the role of the metal oxide support. In this project, we will use a combination of beyond-state-of-the-art computational techniques, experimental surface modification and advanced characterization to meet these goals.Researcher(s)

Mastering metal-PHOSphonate properties in PORE-size engineered catalysts for bio-refinery processes (PHOSPORE).
Abstract
The pursuit of recovering bio-renewable chemicals from biomass waste is a key aspect in the sustainable resource management targets, put forward in the European Green deal. However, converting these natural waste streams to useful target molecules requires high-performance catalysts with tunable surface groups, porosity and extraordinary stability in the demanding bio-refinery conditions. The reproducible wet-chemical synthesis and structural control of these catalysts forms the central challenge of the PHOSPORE project. More specifically, designed porous networks consisting of an organic-inorganic scaffold based on phosphonate-metal linkages are targeted. The first aim of the project is to tune these interactions, maximizing the catalytic performance of these novel materials. A second objective is to fundamentally understand how the porous phosphonate-metal networks are built. Hereto, the formulation of controlled model materials (i.e., MOFs and clusters) is combined with an in-depth analytical methodology to elucidate the synthesis-properties relations of amorphous (meso)porous metal phosphonates. Eventually, the newly obtained materials will be tested in two representative bio-refinery processes being cellulose to 5-hydroxymethylfurfural conversion and glycerol acetylation. Hence, an essential knowledge leap in the intertwined hybrid porous material development and catalytic platform chemical conversion is anticipated.Researcher(s)

Catalysis for CCU: Valorisation of CO and CO2 via Carbon Capture and Utilization
Abstract
We live in a carbon-based society: carbon is the essential element for products ranging from food to fuels and materials. Yet, the increasing levels of CO2 in the atmosphere pose a grand societal challenge. Reaching the goals of the Paris agreement by 2050 will require transitioning to a fully circular economy and a carbon neutrality of the industry. But how? We believe that "if you want to go fast, go alone. If you want to go far, go together" (African proverb). Thus, building in Flanders a multidisciplinary network of scientists, connected with well-established research groups in Germany and the Netherlands, focused on Carbon Capture and Utilization (CCU) technologies is an essential step to develop the know-how for the low-carbon circular economy.Researcher(s)

Catalysis for CCU: valorisation of CO and CO2 for carbon capture and utilisation.
Abstract
To sustain our carbon-based standard of living, it is becoming increasingly clear that CCU will play a key role in delivering materials, food, and clean energy storage services. This will require informed policy, education of industry partners, opportunities for researchers to collaborate, and academic symbiosis. We have an impressive level of expertise in Flanders in both biological and chemical (catalytic) conversion of CO2 (which is rather unique). Therefore, we create this Scientific Research Network "Catalysis for CCU" composed of researchers with diverse but complementary backgrounds in the CCU field. Our goal is to build a CCU network relevant to the Flemish/European industrial landscape, focused on sharing best practices and knowledge; stimulating collaboration; exposing young researchers; creating a community; being a go-to place for expertise; and sharing resources that individual researchers and knowledge institutes lack.Researcher(s)

Nanostructuring the surface of porous titanium 3D structures.
Abstract
Titanium and its alloys have been widely used for a broad variety of applications. Their performance and applicability can be extended further when nanostructuring its surface. Nanostructuring comprises the broad range of physical and chemical technologies available to modify the surface topography and/or surface chemistry. The first aspect is related to surface roughness, porosity and pore size distribution, while the surface chemistry points to the ability to form a wide variety of titanium oxides or titanates. The more advanced approaches in nanostructuring enable both full control of the surface structural characteristics and its chemistry. Therefore, the main aim of this PhD is to transfer these nanostructuring approaches onto porous 3D micro-extruded titanium. The technology and expertise to manufacture porous titanium parts by 3D micro-extrusion on the macroscopic level is already available at VITO. However, the knowledge to create surface controllable porous layers in/on these porous materials is still lacking. Therefore, together with the university of Antwerp, 2 strategies will be followed, with different degrees of complexity and controllability.Researcher(s)

InSusChem - Consortium for Integrated Sustainable Chemistry Antwerp.
Abstract
This IOF consortium connects chemists, engineers, economic and environmental oriented researchers in an integrated team to maximize impact in key enabling sustainable chemical technologies, materials and reactors that are able to play a crucial role in a sustainable chemistry and economic transition to a circular, resource efficient and carbon neutral economy (part of the 2030 and 2050 goals in which Europe aims to lead). Innovative materials, renewable chemical feedstocks, new/alternative reactors, technologies and production methods are essential and central elements to achieve this goal. Due to their mutual interplay, a multidisciplinary, concerted effort is crucial to be successful. Furthermore, early on prediction and identification of strengths, opportunities, weaknesses and threats in life cycles, techno-economics and sustainability are key to allow sustainability by design and create effective knowledge-based decision-making and focus. The consortium focuses on sustainable chemical production through efficient and alternative energy use connected to circularity, new chemical pathways, technologies, reactors and materials, that allow the use of alternative feedstock and energy supply. These core technical aspects are supported by expertise in simulation, techno-economic and environmental impact assessment and uncertainty identification to accelerate technological development via knowledge-based design and early stage identified key research, needed for accelerated growth and maximum impact on sustainability. To achieve these goals, the consortium members are grouped in 4 interconnected valorisation programs focusing on key performance elements that thrive the chemical industry and technology: 1) renewable building blocks; 2) sustainable materials and materials for sustainable processes; 3) sustainable processes, efficiently using alternative renewable energy sources and/or circular chemical building blocks; 4) innovative reactors for sustainable processes. In addition, cross-cutting integrated enablers are present, providing expertise and essential support to the 4 valorisation programs through simulation, techno-economic and environmental impact assessment and uncertainty analysis.Researcher(s)

Artificial clathrates for safe storage, transport and delivery of hydrogen II (ARCLATH II).
Abstract
The ARCLATH-2 project aims to overcome current drawbacks in hydrogen transportation and storage by developing a radically new transportation and storage concept based on clathrates. After a year of research, ARCLATH-1 already provided a proof of concept that shows hydrogen can indeed be encapsulated in clathrates under technically and economically relevant conditions, in terms of both pressure and temperature. A follow-up project ARCLATH-2 has now been initiated to maximise the hydrogen storage capacity of the clathrates under similar pressure and temperature conditions. At the same time, ARCLATH-2 will define a practical process of reversible hydrogen storage and delivery based on pressure swing cycling at lab-scale.Researcher(s)

Towards CRM-free supported catalysts for the preferential oxidation of CO in H2-rich streams.
Abstract
In today's world where climate change is a hot topic, burning finite fossil fuels, which contributes to global warming through the production of CO2, still accounts for 85% of the primary energy production. Therefore, the scientific community focusses on the quest of finding cleaner alternative energy sources. A promising alternative is H2. At present, over 95% of all H2 is produced by steam reforming of methane, which has the disadvantage of producing CO as by-product. This causes detrimental effects on several catalysts (f.e. catalysts used in fuel cells or in the ammonia synthesis). Therefore, purification of H2-rich gas streams is required and the most effective approach can be found in the preferential oxidation of CO (CO-PROX). Up to date, many catalysts have been utilized for CO-PROX (mainly noble metal based), however only a few have shown potential for future application. In this project the aim is to provide the next step towards critical raw material-free supported catalysts for CO-PROX. This goal will be pursued by synthesizing innovative mono-/bimetallic Cu-based supported catalysts with ultimate porosity and stability, and excellent catalytically active surface sites dispersion. To contribute to the ultimate goal of sustainability, aqueous based methods will be utilized for the synthesis of the catalysts. Furthermore, innovation is brought to the catalysts by 3D-shaping (collaboration with VITO) and advanced catalytic testing (collaboration with UNIPD, Italy).Researcher(s)

The central research hypothesis is that confinement in nanoporous materials can be used to stabilise hydrogen clathrate hydrates, catalysing their formation to an extent that a new technology for hydrogen storage can be envisioned. Targeted hydrogen storage capacities exceed 5 wt.% and 30 g/L at temperatures above 2 °C and pressures below 100 bar. This exceeds the performance of any of the current hydrogen storage technologies.Researcher(s)

EASiCHEM - Efficiënt Affinity Separations for Chemical Applications.
Abstract
Many chemical companies are nowadays confronted with very challenging liquid separations, aiming at separating molecules with very similar physical properties. The current trend towards more bio-based and/or highly-tailored chemicals, will only increase the number of these demanding separations. These challenges would benefit from efficient Affinity Separations (AS). The most traditional AS technology is liquid-liquid extraction, where the extracting solvent acts as the separation agent (ASA). The most selective AS is liquid chromatography, driven by the affinity between molecules and a functionalised stationary phase, the separation material (ASM). Although successful in different situations, both AS processes have important drawbacks. EasiChem aims at tackling these limitations, by developing more efficient, and/or more sustainable AS processes, focusing on two promising, energy-poor liquid separation technologies : 1. Membrane-based AS processes : bringing the selectivity of chromatography to membrane separations, using functionalised ceramic membranes tailored to match the separation problem; 2. Continuous chromatography : tackling the main disadvantage of selective chromatography, making use of a membrane-contactor-like design at microreactor scale. The work programme is intended to extensively explore, understand and benchmark the capabilities and limitations of the new AS processes using a myriad of functionalized ceramic materials. EASiCHEM is a strategic basic research (SBO) project funded by the Flemish spearhead cluster for the chemical industry CATALISTI. Partners are VITO (coordinator), UGent, KULeuven, UHasselt, UAntwerpen, VUB and UCL.Researcher(s)

Understanding the material structure-activity correlation in plasma catalytic CO2 conversion (PLASMACAT).
Abstract
Plasma catalysis is a new emerging field of conversion technology, particularly focused on converting relatively stable gases such as CO2 to basic chemical building blocks by using electrical energy. It consist of highly energetic accelerated electrons producing a cocktail of activated species such as ions, radicals and excited species. To be able to enhance its energy efficiency and create selective conversions, packing materials and catalysts are being introduced in the plasma. Although it is well accepted that there is a mutual interaction of the materials on the plasma properties and vice versa, the underlying mechanisms and even more the specific material properties influencing plasma conversion, selectivity and energy efficiency are still largely unknown. Therefore, a systematic study applying know-how of the applicant and supervisor in controlled material synthesis will be integrated in plasma catalytic studies, a new field of research for the applicant. This will permit a systematic structure-activity correlation, identifying the impact of yet unrevealed material properties on the plasma characteristics and performance (conversion, selectivity and energy efficiency) determined by the specific plasma environment. Focus will be put on studying the impact of metal dispersion and metal support interactions on the plasma characteristics, plasma catalytic conversion and selectivity as well as its stability. Elucidating the role of packing geometry on plasma catalysis is a particular aspect of this MSCA, which is expected to have unique behavior in plasma discharge and characteristics and hence conversion and selectivity. This is a feature distinctive for plasma and not encountered in classical catalytic processes.Researcher(s)

The role of heteroelement containing functional groups on surface modification.
Abstract
Metal oxides possess a high chemical and mechanical stability making them ideal support materials in several applications like catalysis and separations. Unfortunately, metal oxides don't have controllable selective interactions as only hydroxyl groups are present on the surface. Organic surface modification can solve this, creating versatility and affinity. The unique way of coupling the organic functional group to the inorganic matrix influences the properties of both the surface and bulk. The resulting surface interactions created in the hybrid metal oxides critically depend on the particular physico-chemical and structural properties of the metal oxide, the type of functional organic group, the modification method used (Grignard modification or organophosphonic acid (PA) grafting) and the synthesis conditions applied. These high potential organically surface modified materials can open new opportunities in affinity driven separation processes, catalysis, sensing and many other applications if their structural properties can be tailor made and adjusted to the application. Nevertheless, thorough fundamental insights in the influence of synthesis/modifications conditions and reagent types on these physico-chemical surface properties and the resulting interactions between surface and surrounding molecules is lacking, certainly for functional groups other than aliphatic hydrocarbons. This is exactly the aim of this work: it focuses on the impact of the metal oxide support on the interaction with nitrogen containing aromatic and aliphatic organic functional groups. Both PA and Grignard modification will be studied with a main focus on the differences induced in physico-chemical properties due to the N heteroelement. The impact of synthesis conditions, physicochemical properties of the metal oxide, type of modification method and functional groups on the physico-chemical surface properties are being unraveled allowing controlled surface properties. This DOCPRO4 will thus create the crucial fundamental knowledge to correlate synthetic control to physico-chemical properties and molecular interactions of organophosphonic acid and Grignard modified metal oxides.Researcher(s)

Abstract
Till now, plasma catalysis has been studied in different reactors, under divergent conditions and in a fragmented way, making it difficult to obtain systematic information on the different aspects of plasma catalysis. Therefore, the aim of this project is to study the impact of materials, controlled in particular properties (properties of the support such as shape, metal dispersion and metal-support interaction), that have not been studied in a systematic way before, to elucidate some of the underlying mechanisms and properties not yet identified. Specifically, this project aims at unravelling the impact of catalyst dispersion to better understand the impact of the properties of the deposited catalyst with respect to activity, selectivity and its stability in dry reforming of CO2 and methaneResearcher(s)

To obtain a new generation metal sorbents, the choice of materials, structural architecture and control of surface chemistry is crucial. This project aims to develop methodologies to graft specific functional groups in a controlled way to the titania surface. Control and adjustment of the type, dispersion, density and bonding mode of the functional groups to the surface is envisaged to create different interaction sites with the surface, each responding in a specific way with the metal(s) that need to be removed from complex media.Researcher(s)

Influence of the reaction conditions on organic surface modification of titania and their impact on interactions with molecules
Abstract
Metal oxides possess a high chemical and mechanical stability making them ideal support materials in several applications like catalysis and separation. Unfortunately, metal oxides don't have controllable selective interactions as only hydroxyl groups are present on the surface. Organic surface modification can solve this. The most used method is organosilylation, developed for silica materials. However, silica has a limited chemical stability and a necessary evolution to robust and inert supports is needed. Titania and zirconia are good and robust alternatives for silica but organosilylation results in unstable bonding of the functional groups. New and alternative methods like the organophosphonic acid modification and the recently co-developed (by VITO and UA) patented Grignard modification are promising and result in unique surfaces. But thorough fundamental insights in the influence of synthesis conditions on the physicochemical surface properties and the interactions between surface and surrounding molecules is lacking. This is exactly the aim of this work: first the impact of synthesis conditions, type of modification method and functional groups on the physicochemical surface properties is studied. Secondly, differences in the surface properties that have an impact on the interactions of the surface with specific target molecules are identified. Finally, we will set the first steps in solving solvent-solute interactions by looking at the impact of functional groups on membrane filtration.Researcher(s)

Stuyding local interactions of organophosphonic modified surfaces through controlled synthesis, characterization and EPR spin probing
Abstract
Several important applications such as separation and sensors are directly influenced by the materials properties involved. The surface properties and their specific interactions with molecules are key components that needs to be controlled and understood in detail to further progress materials development and performance. Organophosphonic acid modification is a known modification method for metal oxides, adding versatility of interactions of organic molecules to the robust and structural advantages of the inorganic support. Although several studies exist on correlating synthesis conditions with surface properties, detailed knowledge on their impact on specific interactions with molecules at the molecular scale are still lacking. Therefore, we would like to combine knowledge on controlled synthesis and material characterization with studies of dynamic local interaction behavior via in-situ EPR with spin probes and in-situ IR. We aim at: elucidating the correlation of synthesis conditions and the resulting surface properties to local interaction behavior influenced by contributions of the (packing density and type of) functional groups, un-bonded reactive groups of the organophosphonic acid and the titania surface, together determining the observed overall adsorption behavior. Moreover, we aim at revealing important aspects of the surface modification mechanisms by studying the probe mobility during grafting, in and with the surface grafted layer.Researcher(s)

Creating structural and physico-chemical control to enhance properties of hybrid periodic mesoporous metal phophonates.
Abstract
Hybrid organic-inorganic materials add organic functionality to inorganic material properties. Attention has shifted from silica based materials towards non-silica hybrid materials. Although a lot of progress has been achieved in surface grafting of organic functional layers, materials with framework incorporated organic groups can induce specific properties not achievable by surface functionalization. Tremendous progress has been reported on hybrid microporous materials such as metal organic frameworks (MOF's). But less attention has gone to mesoporous hybrid metal oxides, prepared by interaction of metal oxide precursors with di-organophosphonic acids (RO)2O-P-R'-P-O (OR)2, intrinsically having the same high potential as the silica based PMO's (periodic mesoporous organosilicates). Research on these periodic mesoporous metal phosphonates is scarcer due to the complexity of controlling the materials properties during template assisted synthesis. We aim at creating the required knowledge to control their structural and physico-chemical properties by revealing the impact of precursor type and amount, synthesis conditions and kinetics of condensation. In addition, developing strategies to solve the often reported need for stabilization. In-depth complementary advanced characterization techniques will be applied to unravel the materials properties correlated to the specific synthesis and stabilization, revealing underlying mechanisms to control their properties and stability.Researcher(s)

Membrane proces for the separation of mixtures of fatty acids and their derivatives
Abstract
Oleochemical are already an alternative renewable source of petrochemicals. Industrial processes of fatty acids and methyl esters of fatty acids (FAME's) have to apply mixtures of oils, even if there are unwanted compounds in it due to the cost and challenges of separation. This inhibits their wider Industrial use or enhances costs of separation. A separation into its individual components could increase the market potential and open new markets for fatty acids and their derivatives. The goal of this PhD research is to develop a possible alternative separation methodology for fatty acids and their derivatives based on functionalised ceramic nanofiltration membranes. The goal is to reach higher separation efficiencies than the currently applied technology while using a less energy demanding method, lowering the cost of the separation.Researcher(s)

Abstract
Although much research is focused on the synthesis of materials and their applications, the attention for understanding the impact of structural and physicochemical properties on the performance of materials in various applications is an interesting, challenging field that still requires a lot of efforts. Indeed, the know-how on this matter can provide valuable feedback in order to control the synthesis of materials with properties engineered and adjusted to the specific applications as well as important know-how for more process related and application driven studies. It is the indispensable bridge between material design and development, technology and applications. In addition, synthesis methods are often first developed for powder applications. However, supported layers and coatings are frequently needed in several applications since they are technologically essential (e.g. membranes), avoid leaching or toxicity [ ] etc. A good know-how on the impact of the support on the structural and physicochemical properties of the layer with respect to the powder synthesis or modification is crucial to allow a fast translation of the good and controllable properties of powders to coated materials. Therefore, my research will focus on studying the structural and physicochemical surface properties (obtained via controlled synthesis) in order to rationalize their superior or inferior performance in several selected applications as well as modifying these porous materials via post-synthesis treatments to alter their physicochemical properties and interactions with molecules. The main materials that will be studied are on the one hand mesoporous titania materials (powders, films and membranes) for photo-induced processes (e.g. photocatalysis and photovoltaïcs) and separation and on the other hand functionalized materials (hybrid organic-inorganic materials and zeolitic modified materials) with focus on the interaction of molecules with the functional groups. The main topics will be: 1) Mesoporous titania materials for photo-induced applications 2) Studying the role of the support on thin film and membrane preparation 3) Hybrid organic-inorganic functionalized materials and their interactions with molecules. 3.1) Post-synthesis modification of metal oxide powders and membranes 3.2) Periodic mesoporous organosilica materials with enhanced functionalities 4) Mesoporous materials with zeolitic functionalitiesResearcher(s)

The development of titania-based catalysts for photocatalytic degradation and photoconversion processes.
Abstract
This project aims to develop and study the insights of titania-based photocatalysts with tailored properties for the photodegradation under visible light of pollutants from both air and aqueous systems. The goal of this research is to introduce visible light absorption on mesoporous titania by doping or co-doping with different metallic or non-metallic elements. The project will focus on the possible applications of the obtained photocatalysts by testing both the CO2 reforming in the presence of water as well as on the photodegradation of textile dyes from aqueous wastes under visible light.Researcher(s)

Abstract
Although much research is focused on the synthesis of materials and their applications, the attention for understanding the impact of structural and physicochemical properties on the performance of materials in various applications is an interesting, challenging field that still requires a lot of efforts. Indeed, the know-how on this matter can provide valuable feedback in order to control the synthesis of materials with properties engineered and adjusted to the specific applications as well as important know-how for more process related and application driven studies. It is the indispensable bridge between material design and development, technology and applications. In addition, synthesis methods are often first developed for powder applications. However, supported layers and coatings are frequently needed in several applications since they are technologically essential (e.g. membranes), avoid leaching or toxicity [ ] etc. A good know-how on the impact of the support on the structural and physicochemical properties of the layer with respect to the powder synthesis or modification is crucial to allow a fast translation of the good and controllable properties of powders to coated materials. Therefore, my research will focus on studying the structural and physicochemical surface properties (obtained via controlled synthesis) in order to rationalize their superior or inferior performance in several selected applications as well as modifying these porous materials via post-synthesis treatments to alter their physicochemical properties and interactions with molecules. The main materials that will be studied are on the one hand mesoporous titania materials (powders, films and membranes) for photo-induced processes (e.g. photocatalysis and photovoltaïcs) and separation and on the other hand functionalized materials (hybrid organic-inorganic materials and zeolitic modified materials) with focus on the interaction of molecules with the functional groups. The main topics will be: 1) Mesoporous titania materials for photo-induced applications 2) Studying the role of the support on thin film and membrane preparation 3) Hybrid organic-inorganic functionalized materials and their interactions with molecules. 3.1) Post-synthesis modification of metal oxide powders and membranes 3.2) Periodic mesoporous organosilica materials with enhanced functionalities 4) Mesoporous materials with zeolitic functionalitiesResearcher(s)

Optimization of the structure-activity relation in nanoporous materials.
Abstract
The relation between structure and activity will be optimized for two classes of nanoporous materials: TiO2 nanotubes combined with Ag nanoparticles and Periodic Mesoporous Organosilica's. This will be done based on a multidisciplinary approach combining advanced 3-dimensional imaging with modern computational methods at an atomic scale. This will lead to a more direct optimization of the synthesis and activity of the nanoporous materials in comparison to the classic trial-and-error procedures.Researcher(s)

Zeolite-functionalised materials with bimodal porosity.
Abstract
This research project aims the formation of zeolite-functionalised materials via innovative synthesis methods to increase and to control the zeolite character of these materials. An important part of the research includes the characterisation of the structures with bimodal porosity, with special attention to the selectivity towards adsorption processes. For these materials, it is expected that the adsorption-properties will be different in comparison to the classical zeolites and the mesoporous materials with amorphous silica walls. In this project, fundamental knowledge will be obtained on the structure of the zeolite nanoparticles, used to build up the materials. Important information is the size and the crystallinity of the particles. Different synthesis methods will be applied in order to prepare the final materials. Hereby a control on the morphology and the ratio microporosity/mesoporosity in relation to the functionality of the materials is very important.Researcher(s)

These methods not only open the possibility for membranes with high selectivity and tailor-made pore dimensions, but will also result in membranes with chiral selectivity. The performance of the developed membranes will be tested in solvent filtration.

Abstract
The aim of the project is to perform a systematic and fundamental study of the different synthesis conditions which leads to the formation of composite (micro- and mesoporous) materials with incorporated heteroelements. Focus will be on the controlled formation of the pores, the morphology and the coordination, the localisation and the strength of the active elements. Also the possibility to have a controlled variation of the ratio of microporosity/mesoporosity and the diameter of the pores is very important for this type of materials.

Functionalised ceramic membranes for solvent filtration.
Abstract
The application field of ceramic membranes is more and more expanding towards in process separations, which demand solvent stable nanoporous membranes. Ceramic nanoporous membranes are very stable in solvents, however inherently hydrophilic. A tremendous potential for solvent resistant membranes exists for fine-chemical (pharmaceutical, agrochemical, etc.) industry. Therefore, stable ceramic membranes are being developed that exhibit surface organic functional groups to allow strongly improved separations and high fluxes for less polar solvents.Researcher(s)

The research concentrates on the optimalisation on powders and includes post-modification reactions and a detailed characterization. The advantage of post-modifications is that a broad range of functionalities become possible.

Synthesis and optimisation of tailor-made supported titania layers for photo-induced processes.
Abstract
In this project the influence of the synthesis conditions and the applied coating techniques on the final properties of deposited thin layers of titania (TiO2) will be studied. Innovative methods for the formation of porous powders (UA, promotor P. Cool) will be combined with the expertise on the formation of thin layers (UHasselt, promotor M.K. Van Bael). Also post-modification synthetic techniques will be applied in order to further control the stability and the properties of the materials. The scientific knowledge which exists for the formation of powders will be transferred to the deposition of thin layers. In this way, fundamental knowledge on the parameters which control the structure and the properties of the deposited titania materials will be obtained. This is of great importance for photo-initiated applications of the materials.Researcher(s)

The objective of this research project is the development of a new generation of mesoporous materials that combine the benefits of mesoporosity with high selectivity and stability. Two main synthesis approaches are formulated. On one hand, mesoporous materials will be directly combined with zeolites by linking their synthesis to one another. On the other hand, selectivity and stability will be increased by the formation of mesoporous hybrid (organic- inorganic) materials.Researcher(s)

Silica based mesoporous organic-inorganic hybrid materials.
Abstract
The focus of this project is essentially on PMO's (Periodic Mesoporous Organosilica's), a new class of porous hybrid materials. BTEB (1,4-bistriethoxysolylbenzene) is used as a precursor, which results in a structure with crystalline walls. Due to organic functionalisation of the benzene molecule, further modification of the materials is possible. In literature the possible applications of PMO's are frequently mentioned but never explored in detail. Therefore the goal of this research is to investigate the possible use of these materials in applications as catalysis and metal scavenging and to compare them with the already existing analogue functionalized polymer and silicamaterialsResearcher(s)

Such materials can be very interesting in various fiels such as selective catalysis, controlled drug release, adsorption and separation. Their stability will allow them to be used in heavy duty processes.Researcher(s)

Use of textile materials for the elimination of odours and harmful substances in the air by adsorption and catalytic degradation.
Abstract
In order to give special features to textile materials, they can be modified towards a specific functionality. In this project, porous catalysts will be added to a series of different textile materials. The active catalysts will adsorb harmful odours and toxic components (cigarette smoke, sweat, formaldehyde, VOC's) from the indoor air and catalytically degradate them, in order to avoid saturation. The adsorption and catalytic degradation properties of the materials will be tested and optimised, using different titania catalysts and the necessary analytical techniques (main focus will be on the selectivity and the stability of the catalysts).Researcher(s)

The development of composite enzyme/mesoporous silica catalysts with high stability and biocatalytic activity.
Abstract
Functionalised hexagonal mesoporous MSU silica supports with ultra-large pores between 4 and 15 nm are synthesized following a new, environmentally and economically friendly templated synthesis route. In a post-synthesis modification step, the surface of the solids will be functionalised with suitable groups (thiol, chloride, amine groups) that will interact strongly with enzymes. Next the immobilization of a series of enzymes with different sizes on the MSU supports is performed. The influence of the support porosity and surface characteristics on the enzyme loadings are evaluated, as well as the stability of the resulting enzyme/silica composites. Finally, the activity of the enzyme/mesoporous MSU catalysts is assessed in an appropriate biocatalytic reaction.Researcher(s)
