| Abstract: | The typical photocatalytic degradation mechanism of nano-titania on the surface of environmental pollutants is summarized.Some theoretical views of surface modification influence on the respondence to visible-light of the catalyst were introduced.The modified nano-titania,especially nonmetal doped nano-titania,can effectively respond to the visible-light in a wide spectral range.Recent application progresses of nano-titania photocatalyst used in the treatment of the main pollutant source,industrial organic effluents,were presented.Developing trends of nano-titania photocatalytic materials were further prospected. |
