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 η superoxide species and peroxide adspecies at the one-electron defect site to the supported active species of gold for the oxidation of CO.
