Abstract

In this study, TiO₂ was successfully coated on Stober silica beads followed by depositing Au nanoparticles on this core-shell structure. The size of the Au nanoparticles was well controlled in the range of 2 - 7 nm. This composite exhibited high thermal stability. When used as a model catalyst for oxidation of CO at low temperatures, the Au/TiO₂/SiO₂ showed a much higher catalytic activity than the Au/SiO₂ and Au/TiO₂(P25) catalysts.
