摘要：
The oxidation of carbon-monoxide on a series of Cu/Rh(100) model bimetallic catalysts was studied at 458K. Using a reactant gas mixture of CO/O2=2, a maximum catalytic activity was observed at a Cu coverage of 1.3ML. The overall kinetics for CO oxidation on Cu/Rh(100) catalysts was found to be very similar to that on Rh(100). Under reaction conditions, the Cu overlayers are unstable, and, upon interaction with oxygen, form 3-dimensional CuO(x) clusters.
