(1) gas purification environmentally harmful gases can be divided into indoor air pollution gases and harmful gases. Interior decoration materials harmful gases and other major release of formaldehyde and living environment in the onset of methyl mercaptan, hydrogen sulfide and ammonia. Titanium dioxide (with VK-TG01) through photocatalytic oxidation effect can be adsorbed differentiation of these substances in its appearance, then the concentration of these substances in the air drop, reduce or eliminate environmental discomfort. Else, TiO2 in the light of the environment inhibit or kill microbial effect, therefore, titanium dioxide (with VK-TG01) can purify the air, with a deodorizing function. (2) the disposal of organic waste, the effect is very ambitious. Titanium dioxide (with VK-TG01) composite materials for organic wastewater disposal, the effect is very ambitious. TiO2 as the photocatalyst, in the light conditions, water can attack the oxidation of hydrocarbons, halides, carboxylic acid - recovery response, and is gradually degraded, ending completely oxidized to CO2 and H2O environmentally friendly and other harmful substances. New materials Co., Ltd., Hangzhou Wan Jing selection of new silver nano-titanium dioxide composite catalysts for biochemical waste water disposal dyeing and essence of depth after the disposal, after the light 120min, CODcr dyeing wastewater and remove the essence rate 75.3% and 83.4%, respectively. After studies have shown, in the sunlight nanometer TiO2 porous film of dichlorvos disposal solution has an excellent effect. In addition, titanium dioxide (with VK-TG01) can be effectively used for the photocatalytic degradation of industrial wastewater containing CN-.
