Thin Films
The activities of the group are centered around thin film catalyst models. Such models mimic relevant aspects of a real world catalysts, but have a reduced complexity. That allows us to understand catalytic processes in detail. Central activities of the group are the development of thin film preparation recipes and the study of thermal and electrocatalytic reactions at the thin film / gas or liquid interfaces.
Supported catalysts may be mimicked by deposition of metallic aggregates. Several surface-sensitive experimental methods (XPS, TPD, STEM, EELS, IR surface action spectroscopy) are applied under vacuum conditions and at elevated pressures.
