UNIQUE REACTION CHARACTERISTICS OF Rh CATALYSTS FOR THE CO HYDROGENATION BY MEANS OF PSRA
By using PSRA, the rate constant for the formation of surface carbon species, kCO, and that for its hydrogenation, kCHx were determined from dynamics of adsorbed CO and produced CH4 in the CO hydrogenation on supported Rh catalysts. It was found that there was not much difference between these two rate constants, while kCHx was extremely larger than kCO on the other group VIII metal catalysts.
