摘要

The CO oxidation reactivity of nanoporous Au thin films with W impurity (∼5% of Au) was studied. No CO oxidation is observed at room temperature. At 160°C, the conversion of CO to CO2 was observed. Decomposition of the carbonate species on the surface is the rate-determining step of the CO oxidation reaction.
