Visible light-induced degradation of methylene blue on S-doped TiO$$_{2}$$

Umebayashi, Tsutomu; Yamaki, Tetsuya; Tanaka, Shigeru; Asai, Keisuke*

A sulfur (S)-doped titanium dioxide (TiO$$_{2}$$) photocatalyst was synthesized by oxidative annealing of titanium disulfide (TiS$$_{2}$$). TiS$$_{2}$$ turned into anatase TiO$$_{2}$$ when annealed in air. The residual S atoms occupied O-atom sites in the TiO$$_{2}$$ to form Ti-S bonds. The S doping caused the absorption edge of TiO$$_{2}$$ to be shifted into the lower energy region. Consequently, methylene blue adsorbed on the S-doped TiO$$_{2}$$ was photocatalytic decomposed by visible light irradiation.
