Abstract

S-doped SrTiO3 was synthesized by the solid state reaction method between S and SrTiO3 power under the N2 flow. The effect of temperature, calcination time and S-content on the formation and photocatalytic activity of SrTiO3 were investigated. The morphology and properties of obtained powders were characterized by XRD, UV-DRS, UV-VIS, SEM, BET. The photocatalytic activities of S-doped SrTiO3 was also investigated through the decomposition of methylene blue. As a result, the 10 %S-doped SrTiO3 contributed to the decrease of band gap energy to 2.73 eV and enhanced the photocatalytic activity for methylene blue degradation of 74.5 % after 180 min irradiation.
