Titanium dioxide (TiO2) doped with sulfur (S) was synthesized by oxidation annealing of titanium disulfide (TiS2). According to the x-ray diffraction patterns, TiS2 turned into anatase TiO2 when annealed at 600βΒ°C. The residual S atoms occupied O-atom sites in TiO2 to form TiβS bonds. The S doping c
