Abstract
Using modern methods and approaches of surface science, the model supported catalysis Au/AlOx and Ag/HOPG were studied in the reactions of NO decomposition and ethylene oxidation, respectively. It is assumed that a combination of X–ray photoelectron miscoscopy and scanning tunneling microscopy turns out to be very informative in establishing the reasons of the catalytic action of model catalysts and can be used in the studies aimed at improvement of the catalytic properties of real catalysts.
