Photocatalytic processes using TiO2 as catalyst have attracted extensive attention for various environmental applications. The electrons/electron-hole-pairs irritated by lights could generate highly oxidative radicals to decompose organic contaminants into simple inorganic species through chain reactions. Although titanium dioxide using UV radiation has become the benchmark photocatalyst for degradation of pollutants, some efforts have been made to develop the visible light assisted photocatalysis. This article make a brief review on the development the visible light assisted TiO2 photocatalysis, such as rare metal doping, mixed-photocatalyst, plasma reduction and photo-sensitization.
