TiO2 Crystal Structure Dependence of Low-temperature CO Oxidation Catalyzed by Au/TiO2
The effect of TiO2 crystal structures (rutile, anatase, and brookite) on low-temperature CO oxidation catalyzed by Au/TiO2 was determined. The catalytic activities of Au/TiO2 with different TiO2 crystal structures are identical when the Au loadings and mean diameters are equal. Additionally, the present work confirmed that the active sites of Au/TiO2 catalysts are at the perimeters of supported Au nanoparticles. The present results will contribute to theoretical calculations for the clarification of the mechanism of Au/TiO2-catalyzed CO oxidation.
