| 摘 要： | 以钛酸丁酯为原料,采用溶胶-凝胶法制备了纳米TiO2粉末,在其中添加了过渡金属元素铁,并在表面包覆少量的表面活性剂(CTAB)。经紫外光照射后,通过紫外-可见分光光度计测量了光催化降解反应后降解率的变化,探讨了在两者共同作用下的TiO2粉体的光催化活性。实验结果表明:在样品中掺杂一定量的Fe3+并包覆表面活性剂(CTAB),TiO2的结构上并没有发生改变;在Fe3+和CTAB的作用下的纳米TiO2的光催化活性有了显著地提高。

| Abstract: | Nano-TiO2 powder was prepared by sol-gel route.We used the butyl titanate as raw materials,doped with iron which is one of the transition metal elements,and coating a small amount of hexadecyl trimethyl ammonium bromide(CTAB)as surfactants.After irradiation of UV measurement of the photocatalytic degradation re-action rate of degradation of Change carry out by UV-Vis,the photo-catalytic activity of TiO2 powder under these effects are disscused.The experimental results show that a certain amount of surfactan... |
