摘要 以钛酸丁酯、硝酸银为原料,采用溶胶-凝胶法制备不同浓度Ag掺杂TiO2光催化剂。分别采用X射线衍射(XRD)、扫描电子显微镜(SEM)、光电子能谱(XPS)、紫外可见漫反射(DRS)及荧光光谱(PL)等测试方法对样品晶体结构、表面形貌、化学成分和光学性质进行表征。以罗丹明B溶液(RhB)为目标降解物,分别采用汞灯与氙灯为光源,研究xAg-TiO2x=1%,2%,4%,6%,原子分数)光催化剂在紫外光和模拟太阳光照射下的光催化活性。结果表明:Ag的加入降低了光生电子空穴的复合率,增加了对模拟太阳光的吸收,紫外光以及模拟太阳光的光催化活性均得到提升。1% Ag-TiO2表现出最好的光催化活性,在紫外光及模拟太阳光下对RhB的降解率分别为91%与89%,是纯TiO2的1.18倍和1.24倍,反应速率常数k分别为0.01257 min-1和0.01150 min-1,是纯TiO2的1.49倍和1.74倍。

Abstract:Ag-TiO2 photocatalysts with different doping concentration were prepared by sol-gel method using tetrabutyl titanate and silver nitrate as raw materials. The crystal structure, surface morphology, chemical composition, optical properties of the samples were characterized by XRD, SEM, XPS, DRS and PL, respectively. The photocatalytic activity of xAg-TiO2(x=1%,2%,4%,6%,atom fraction) under UV light and simulated sunlight was evaluated by the degradation of Rhodamine B by using mercury lamp and xenon lamp as the light source, respectively. The results indicate that the photocatalytic activity of TiO2 under UV light and simulated sunlight enhances as the recombination rate of photogenerated electron-hole decreases and the absorption of simulated sunlight increases by Ag doping. 1%Ag-TiO2 exhibits the best photocatalytic activity. The degradation rates of Rhodamine B are 91% under UV light and 89% under simulated sunlight, which are 1.18 and 1.24 times higher than that of pure TiO2. The reaction rate constants are 0.01257 min-1 and 0.01150 min-1, which are 1.49 and 1.74 times higher than that of pure TiO2.
