Theoretical and Experimental Chemistry Aims and scope

Abstract

The steady-state rate of hydrogen oxidation catalyzed by platinum on an inert support (corundum) is greater than the rate of oxidation of carbon monoxide, while the rate of hydrogen oxidation on a platinum-vanadium catalyst is less than the rate of oxidation of carbon monoxide. The conditions for the complete selective oxidation of the reaction mixture components were determined. Hydrogen is oxidized on the Pt/corundum cataljst at 273‡K in a non-steady-state mode, while CO is oxidized on the same catalyst at 273 ‡K and on Pt/BaSO4-V2O5 at 383–393‡K in a steady-state mode.
