Abstract

We found that twinned gold nanoparticles (T-AuNPs) are generated at a high probability by CO treatment of TiO2-supported Au(III) at room temperature. Because of the formation of T-AuNPs, the Au/TiO2 prepared by the CO treatment showed higher catalytic activity for CO oxidation than Au/TiO2 prepared by conventional H2 treatment.
