Abstract

The dynamics of metal atom deposition on a flat metal substrate in the diffusion mode has been studied. Conditions for growing up the periodic structures with a developed surface morphology are found. The applicability of the results obtained to the manufacture of catalysts is analyzed. In particular, when platinum atoms are deposited on a gold substrate, which is expedient by cost reasons, a system of nanopyramids confined by (111) facets can be formed under special conditions. This structure possesses an ultrahigh catalytic activity and is promising for applications in chemical industry.
