Abstract: Sulfur-doped TiO2 nano particles were prepared by acid catalyzed sol-gel method. By changing the doped content of sulfur and sintering temperature, we got nano-TiO2 under different conditions. XRD and TEM results indicate that sulfur-doped TiO2 is about 20nm. The UV-visible spectrophotometer is applied to measure the absorbance of methyl orange before and after light exposure. The results show that when S/Ti is 1.75, we can get optimum photocatalytic activity of S-doped TiO2 at 500℃.
