CO oxidation over a Pt-Rh system. 1. Reaction on individual metals
The reaction of CO oxidation over thin films of rhodium and platinum prepared by vacuum evaporation of the metals on an inert support has been investigated at low pressures (P < 2x10(-5) mbar). Rhodium has been found to be more active than platinum in this reaction. The reasons of the higher activity of Rh are discussed.
