Recent Advances of Photocatalytic Degradation of Dyes Using TiO_2-based Photocatalysts

The recent advances and mechanism of photoc atalytic degradation of dyes using TiO2-based photocatalysts were reviewed in this paper.The effecting factors produced on photocatalytic degradation,such as pH value,amount of catalyst,dopant contents,calcination temperature and ultrasound,had been discussed in detail.Finally,the prospect of their application for photocatalytic degradation of dyes using TiO2-based photocatalysts was presented.
