Abstract

Abstract: The titanium dioxide (TiO₂) photocatalysis technique, a new and advance oxidation method, has been applied for waste water treatment because of direct utilization of solar energy. But it can only utilize part of solar energy by absorbing UV light which results in lower utilization efficiency of solar energy. Many efforts on improvement of TiO₂ photocatalysis properties have been carried out. In this paper new progresses about TiO₂ photocatalysis mechanics and technology about metal doping, nonmetal doping and co-doping are reviewed. And the ratio of TiO₂ photocatalysis and photocatalytic efficiency to visible light by doped TiO₂ was analyzed and compared. Finally, the development tendency in this field was proposed.

Key words: TiO₂, photocatalysis, doping, modification
