摘要：
A visible light (490-780 nm) was introduced into the process of oxidizing CO over a TiO2 supported Au nanoparticle catalyst (Au/TiO2). It is found that the visible-light irradiation can promote the oxidation of CO over Au/TiO2. Based on the results of both the optical absorption of Au/TiO2 and the adsorption of CO over Au/TiO2, it is proposed that the localized surface plasmon resonance (LSPR) of Au nanoparticles induced by the visible-light would promote the adsorption of CO and its activation at the surface of Au species, resulting in the promoted oxidation of CO over Au/TiO2.
