摘要

以四氯化钛、硫脲、有机羧酸、氨水、D-山梨醇等为主要实验原料,常温常压条件下采用新型络合-控制水解法制备S掺杂纳米TiO₂透明溶胶,该溶胶的平均粒径为4.1 nm.使用XRD、纳米激光粒度分析仪、UV-Vis表征样品的物相、粒径、吸收光谱和光催化性能.此外,还对合成过程中反应条件对结果的影响进行了研究.结果表明,S掺杂质量分数为0.5%,回流时间为15 min时,S掺杂纳米TiO₂透明溶胶的光催化性能达到最优.

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
