摘要：
The catalytic oxidation of carbon monoxide has been studied over transition metal oxides in the absence and presence of platinum. A characteristic activity pattern was observed in both cases, with platinum reducing the temperature at which oxidation was initiated by between 20 and 200 K. The results show that platinum-metal oxide interactions are important in the system. These appear to involve the reaction of carbon monoxide adsorbed on the metal with oxygen associated with the metal oxide lattice.
