Experimental Research of Visible Light-Induced Photocatalytic Oxidation Effects of SO₂ by N-Doping Nano-TiO₂

Abstract:

N-doping nanoTiO2 was prepared by sol-gel method. The TEM,XRD,XPS,BET and UV techniques were used to characterize the crystalline structure.The photocatalytic oxidation effects of SO2 were studied with the fluorescence lamp illumination under the different conditions. The visible light-induced photocatalytic oxidation mechanisms of SO2 were discussed. The results showed that N-doping nanoTiO2 increase the visible-light responsive photocatalytic activity because of the increase of the surface area, O2 lacuna and small particle diameter. There are the optima of the dosage and amount of O2. The removal efficiency of SO2 was greater than 95% under the experimental conditions. The photocatalytic reactions of SO2 included two parts-adsorption and oxidation. The results provide some references for the SO2 control and further application of nanoTiO2.
