【Abstract】 When the TiO 2-water system is irradiated under the ultraviolet light, the surface of TiO 2 will produce OH· radicals and super oxide ions O 2 -. The application of this property to treat organic pollutants in water was noticed by many environmental researchers. This paper reviews the development on research and application of TiO 2 photocatalytic oxidation, including the effective factors, photoelectrocatalysis and the utilization of solar energy.更多还原
