摘要：
Oxidation of methane over Pt/Al(2)O(3) and Pt/CeO(2) catalysts was studied by transient gas-flow reactor and in situ FTIR spectroscopy experiments. The Pt/CeO(2) catalyst is generally more active, indicating more efficient CH(4) dissociation, especially during oxygen pulsing, which likely is connected to the higher oxygen storage capacity/mobility of ceria.
