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TiO_2透明溶胶,该溶胶的平均粒径为4.1nm.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15min时,S掺杂纳米TiO_2透明溶胶的光催化性能达到最优. Sulfur-doped nganic carboxylic acid,NH3 hydrolysis method at roomano TiO2 transparent hydrosol was synthesized by using TIC14, thiourea, or-H20,D-sorbitol etc. as raw materials, through a novel complexation-controlledtemperat4.1 nm. The phase structure, particleure and atmospheric pressure. The hydrosol average particle size is size, composition, absorbance spectrum, and photocatalytic perform-ance of samples were characterized by XRD,nano laser particle size analyzer and ultraviolet-visible spectro-photometer. Furthermore, the effect of reaction conditions on the synthesis process was also studied. Theresults show that the photocatalytic performance of sulfur-doped Ti02 hydrosol was optimal when the do-ping content of S was 0.5%and the reflux time was 15 min.
