Paper Title:
SiO2 (core)-TiO2 (shell) Structure as Catalyst Support for Oxidation of CO at Low Temperatures
  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.
