TiO_2 Photocatalyst and Its Application in Water Treatment / 环境与健康杂志

ABSTRACT

The paper reviews the basic mechanism of photocatalytic oxidation, the kinds of photocatalyst, the characteristics of TiO2 and the commonly used carriers of TiO 2 photocatalytic oxidation in water treatment, the degradation of organic pollutants in water by photocatalytic oxidation and the applications of this new technique in tap water purification. The photocatalytic oxidation as a new technique of environmental protection is being much con-cerned widely.
