摘要：

TiO2 powder grafted with Cr-III ions was demonstrated to become a novel type of hybrid photocatalyst. It could decompose 2-propanol into CO2 via acetone under visible-light (450-580 nm) irradiation. The reaction is explained by the photoinduced direct charge transfer from surface Cr-III ion to the conduction band of TiO2, in which injected electron into the conduction band reduces oxygen and the Cr-IV oxidizes 2-propanol.
