Most volatile organic compounds (VOCs) result in water pollution, air pollution, and even global warming. Among the methods of VOCs decomposition, photocatalyst is the greatly interesting field because it is easy to react under UV and visible light source at room temperature. Research on enhancement of the photocatalytic properties of catalyst is performed by doping metal or non-metal elements. In this study, V-doped TiO2 is selected as photocatalyst and prepared by a sol-gel method under various acidic conditions. These samples are characterized by UV/Vis spectrophotometer for the band gap change and the optical property. Photocatalytic activity of V-doped TiO2 is evaluated through methylene blue (MB) discoloration by decomposition. Based on the MB decomposition rate for specific sample, degradation ability of doped TiO2 is confirmed by the concentration of p-xylene in the closed chamber for the UV irradiation time. |
