Abstract

Sulfur–doped TiO2 were prepared by sol gel method using thiourea as sulfur source. The amount of thiourea solutions are 0; 0.5; 1.0; 1.5 and 2 ml, respectively. Sulfur-doped TiO2 was calcinated at 450 °C. Sulfur-doped TiO2 and pure TiO2 were characterized by X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM). Photocatalyst tests were carried out undersunlight and UV lamp. Based on XRD characterization, the samples are anatase phase. And particle size was calculated using Scherrer equation and results of  8.94 and 12.98 nm, respectiely for TBT-1.5 and TBT-0.5. TEM characterization showed that particle size of sulfur-doped TiO2 and pure TiO2 are 8.6 and 12.5 nm. Compared to undoped TiO2, sulfur-doped TiO2 has a better photocatalyst activity for degradation of remazol golden yellow under visible light.
