Thermal catalysis

The goal of the investigations is to gain an increased understanding of the complex catalytic reactions, for applications in the production of technical catalysts to enhance the reaction rates and improve the selectivity. Our approach is to use appropriate model systems that can be structural and chemically characterized by established surface science techniques for later operando investigations [1]. For this, we use in particular High Energy Surface X-Ray Diffraction (HESXRD) [2], Planar Laser Induced Fluorescence (PLIF) [3], Near Ambient Pressure XPS (NAPXPS) [4] and 2D-Surface Optical Reflectance [5]. The catalytic reactions we seek to understand are CO oxidation, CH4 oxidation, NH3 oxidation, CO2 reduction and CO hydrogenation.
