KULeuven: Oppervlaktechemie en Katalyse-Karakterisatie en Applicatie Team (COK-KAT)

General expertise of the research group

The research team has a strong focus on porous materials, catalysis and adsorption. The emphasis is on three major themes related to grand societal challenges: water, energy and human health. Energy research is concentrated on renewable fuels (solar hydrogen and ammonia), and hydrogen, CO2 and green methane
storage in clathrate hydrates. Molecular aspects of water upon confinement in nanopores relevant to electrolytic processes and molecular storage are investigated.

Specific hydrogen- related expertise & research topics

• Storage of hydrogen, methane and carbon dioxide in clathrate hydrates
• Green ammonia production and cracking, circular nitrogen economy

Available equipment/tools

• Workstation for advanced testing of photoelectrochemical cells & components, electrolysis lab-scale units
• Analytical equipment including ion chromatography, mass spectrometry
• Solid state NMR spectroscopy and XRD for characterizing hydrogen storage materials

Participating in FL/B/EU funded projects with H2 related research

• PROCURA (BE – ETF)(KUL/Energyville, Waterstofnet, VUB, ULiège): Power-to-X and carbon capture & utilization roadmap for Belgium
• HyPErFarm (EU – H2020)(KUL, Aarhus, Fraunhofer): Hydrogen and photovoltaic electrification on farm
• ARCLATH II (FL – Moonshot cSBO): hydrogen storage in artificial clathrates
