| 摘 要： | 以硫脲为S的源物质，以钛酸丁酯为TiO2的前驱体，以蜂窝陶瓷为载体，采用改进的溶胶-凝胶-浸渍提拉法制备Ti1-xSxO2薄膜，探讨热处理温度、S掺杂量及涂膜等工艺条件对Ti1-xSxO2薄膜的光催化活性的影响。研究结果表明：掺硫TiO2光催化剂在可见光区的吸收强度增大；采用溶胶-凝胶-浸渍提拉法制备Ti1-xSxO2光催化剂的最佳工艺条件是：硫脲与Ti（OBu）4摩尔比为3：1，煅烧温度为600℃，涂膜层数为6。在最佳工艺条件下制备的Ti1-xSxO2纳米薄膜对亚甲基蓝的降解率可达100％。

| Abstract: | With thiourea as the source substance of S,with Titanium tetrabutoxide(Ti(OC4H9)4 as the precursor of titanium dioxide and with honeycomb ceramics as carriers,S-TiO2 films were prepared by a modified sol-gel-dipping process.Effects of the heat treating temperature,the amount of sulfur-doping and the technological conditions of coating films on the photocatalytic activity of Ti1-xSxO2 films were discussed.The results show that the adsorption activity of TiO2 photocatalysts with suitable sulfur-doping in visi... |
