摘要
Dimethyl-disulfide (DMDS) is one of sulfur-containing volatile organic compounds (VOCs) with high toxicity, irritating and strong corrosive. Photocatalytic oxidation has been widely reported as a good method to decompose organic environmental pollutants because of its non-toxicity, fast oxidation rate, and chemical stability. The sulfur and transition metal co-doped TiO2 catalysts were prepared by a sol-gel method in this study. The physical and chemical properties of these photo-catalysts were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and Fourier transform-infrared spectroscopy. Compared to pure TiO2 and S/TiO2, sulfur and Zn co-doped TiO2 catalysts can reduce lattice parameter and all photo-catalysts are anatase structures. The XPS spectra confirm that Zn2+ is adsorbed on the surface of TiO2. S0.05Zn0.001/TiO2 shows the best photocatalytic activity and S-VOCs tolerance for the degradation of dimethyl disulfide under visible irradiation.
