| Abstract: | The principle of decompounding the indoor air pollutant by using Nano-TiO2 photochemical catalysis is introduced, and the influences of granule size of Nano-TiO2 on the ability of photochemical catalysis are analyzed. The experiment indicates that the Nano-TiO2 can decompound the air pollutant effectively and the mutative relations are concluded between the photochemical catalysis effect and the velocity of air flow, the pollutant density and the ultraviolet ray intensity. Finally the questions which should pay attention to the development of the Nano-TiO2 photochemical catalysis technology are pointed out. |
