Charge-transfer interaction and catalytic properties

Topics of Research

What is the impact of a solid support in catalysis? This question can be asked looking at different catalytic reactions, support materials and active phase. We like to consider all of them, by modifying the support material (different synthesis methods, materials, and surface areas), active phase (noble metal or nitride/carbide) and reaction (oxidation reactions for depollution, water-gas shift reaction). Will we find the holy grale? Probably not, but maybe get a step closer to interplay of these different parameters…
