Spectroscopic evidence for the supply of reactive oxygen during CO oxidation catalyzed by gold supported on nanocrystalline CeO2.
Nanocrystalline CeO2 supplies reactive oxygen in the form of surface eta1 superoxide species and peroxide adspecies at the one-electron defect site to the supported active species of gold for the oxidation of CO.
