Abstract
Oxidation of methane over Pt/Al2O3 and Pt/CeO2 catalysts was studied by transient gas-flow reactor and in situ FTIR spectroscopy experiments. The Pt/CeO2 catalyst is generally more active, indicating more efficient CH4 dissociation, especially during oxygen pulsing, which likely is connected to the higher oxygen storage capacity/mobility of ceria.
