Abstract

When the TiO2- water system is irradiated under the ultraviolet light, the surface of TiO2 will produce OH· radicals and super-oxide ions O2-. 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 TiO2 photocatalytic oxidation, including the effective factors, photoelectrocatalysis and the utilization of solar energy.
