Open publisher page 0 citations

Abstract

In recent years,nanometer TiO 2 photocatalysis has the potential to degrade environmental pollutants.The contaminants can be mineralized to CO 2,H 2O and other small molecules,so it can be applied in the treatment of waste water,purifying air,killing germ.The paper deals with the method of nanoparticle TiO 2 preparation and the mechanism of photocatalysis on TiO 2,the developments in TiO 2 photocatalysis and its application prospects for pesticides,medicine,chemical industry,environmental engineering and so on were introduced.
