Since the 1980 s, the titanium dioxide catalyzed by light, shows a huge development potential. It can catalysts of azo dye, halogenated hydrocarbon and organic chlorine, phenol, aniline and other photodegradation of organic wastewater. In this paper, the catalytic mechanism of titanium dioxide and catalytic photodissociation of apricot yellow solution (C12H13ClN4), from titanium dioxide dosage, initial substrate concentration, reaction conditions and pH value four aspects comprehensive elaboration of tio2 photocatalytic activity.
