AbstractThe physicochemical properties of nanosized Au catalysts supported on doped CeO2 and their catalytic performance for the CO oxidation reaction were investigated. The Au/Zr-doped CeO2 catalyst is much more active than undoped Au/CeO2, while Au/ZrLa-doped CeO2 shows the highest activity. Characterization of the catalysts by X-ray diffraction, transmission electron microscopy (TEM), high-resolution TEM, and the X-ray absorption fine structure technique shows high homogeneity of the oxide supports and well-dispersed nanosized Au nanoparticles. Raman spectroscopy, X-ray photoelectron spectroscopy, and H-2-tempeature-programmed reduction show that the surface oxygen species are the main factor for the catalytic activity in the CO oxidation reaction, while the supported Au species can improve the redox properties and create oxygen vacancy sites on the support. The oxidation state of Au is not the main factor governing the activity of Au/doped-CeO2 catalysts. Additionally, the synergistic effect of Zr and La is discussed.
