Abstract: S-doped rutile TiO2 photocatalyst was synthesized by an in situ hydrothermal method. The powders were characterized by XRD, TEM and UV-Vis absorption spectra. The photocataJytic activities of doped TiO2 were investigated in the degradation of methylene blue solution. The results show that the catalytic performance of S-doped TiO2 treated at 180℃ is better than that of undoped and S-doped TiO2 treated at 200℃.

Key words: titanium dioxide, doping, photocatalysis
