Oxygen-assisted reduction of Au species on Au/SiO2 catalyst in room temperature CO oxidation.
An unexpected oxygen-assisted reduction of cationic Au species by CO was found on a Au/SiO(2) catalyst at room temperature and the produced metallic Au species plays an essential role in CO oxidation on Au/SiO(2).
