The S-doping caused the photon-to-carrier conversion in the energy region below the band gap of pure TiO2. The photocatalyst applications of the S-doped TiO2, therefore, are of great importance. Synthesized S-doped TiO2 powders were characterized by SEM, EDS, XRD, UV-vis, FT-IR and Raman spectroscopy tests. The photocatalytic activity of S-doped TiO2 powder and Degussa p-25 was evaluated using UV-vis absorption spectroscopy through degradation of methyleneblue (MB) solution. The S-doped TiO2 powders with size similar to 50 nm were successfully prepared by thermal hydrolysis method. Only anatase phase was detected by Raman results for S-doped TiO2 powders calcined at 600 degrees C for 70 min. Photocatalytic activity of sample for degradation of methylene blue showed that 0.56% S-doped TiO2 under visible light has higher photocatalytic activity than Degussa p-25. (C) 2011 Elsevier B. V.
