Study on photocatalytic degradation of organic pollutants in water by using nanometer titanium dioxide

Studies have shown that TiO 2 had obvious advantages in photocatalytic degradation of organic pollutants in water.In this paper the effects of factors such as pH value,surface modification of TiO 2,the support,exterior oxidants and others etc.,on the photocatalytic activities of TiO 2 when it photocatalytically degrades organic pollutants in water have been summarized.Meanwhile the driving effects of photoelectric catalyzing and solar energy utilizing on photocatalysis have been discussed.Its development trend and existing problems in it have also been pointed out.
