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
