Nanostructured Model Catalysts

(B. Klötzer, S. Penner)




Bridging the pressure gap and the materials gap between catalysis-oriented surface science and real catalysis by running catalytic reactions in high-pressure cells interfaced to UHV surface analysis stations, resp. in vivo high-pressure XPS reaction monitoring. Preparation of real and inverted model catalysts using different oxide supports and bimetallic catalyst nanoparticles. Determination of the microscopic structure by transmission electron microscopy (TEM), atomic force microscopy (AFM), and impact collision ion scattering spectroscopy (ICISS). Characterisation of the electronic properties by (high-pressure) XPS, UPS and impedance spectroscopy, and of the catalytic properties by thermal desorption, mass spectrometry and gas chromatography.
