In heterogeneous catalysis the conversion of the reactants is effected by adsorption, surface reaction and desorption. In this collaborative research centre the influence of the interface oxide/metal for oxide-supported metal catalysts shall be investigated systematically with respect to catalytic activity and selectivity.
The collaborative research centre is divided into three research areas. Starting point of the investigations will be a heterogeneous catalyst, which is studied and characterized under real conditions using spectroscopic methods (research area A). In order to get the necessary information to formulate a microscopic model there are two other research areas: in area B metal support systems shall be prepared using special synthetical methods, whereas in area C metal clusters shall be deposited on well-defined solid surfaces, which are characterized concerning the chemical activity. The necessary theoretical basis shall be created in subprojects in the field of quantum mechanics, which belong to the research areas B and C depending on the topic.
Another field of work of this collaborative research centre is the investigation of reactions of oxide-supported metal catalysts included in microporous matrices eg. zeolites.
Main focus of the first period of financial support ending in the middle of 2003 is the system copper on zinc oxide, which is used in methanol synthesis.
