Abstract

Abstract: Sulfur-doped nano TiO₂ transparent hydrosol was synthesized by using TiCl₄,thiourea,organic carboxylic acid,NH₃·H₂O,D-sorbitol etc.as raw materials,through a novel complexation-controlled hydrolysis method at room temperature and atmospheric pressure.The hydrosol average particle size is 4.1 nm.The phase structure,particle size,composition,absorbance spectrum,and photocatalytic performance of samples were characterized by XRD,nano laser particle size analyzer and ultraviolet-visible spectrophotometer.Furthermore,the effect of reaction conditions on the synthesis process was also studied.The results show that the photocatalytic performance of sulfur-doped TiO₂ hydrosol was optimal when the doping content of S was 0.5% and the reflux time was 15 min.

Key words: nano-TiO₂ transparent hydrosol, sulfur-doped, minimum particle diameter, photocatalysis
