Research Advances of TiO_2-Based Photocatalytic Degradation of Dye Wastewater

The research advances and mechanism of TiO2-based photocatalytic degradation of dye wastewater were reviewed. The influence factors on photocatalytic degradation,such as pH value,amount of catalyst,dopant contents,calcination temperature and ultrasound,had been introduced briefly. Finally,the application prospect of TiO2-based photocatalytic degradation of dye wastewater was presented.
