摘要： 采用溶胶—凝胶法制备了Zn2+、Sn4+复合掺杂的TiO2光催化剂,通过XRD、TEM、UV—Vis测试手段对样品进行分析,以对硝基苯酚为研究对象,对其进行光催化降解。结果表明:复合掺杂Zn2+、Sn4+提高了催化剂对波长在200—450 nm范围内的光的吸光度,发生"红移"。在氙灯激发下,其催化活性优于纯TiO2。

Abstract: Photocatalyst TiO2 of Zn2+ and Sn4+ composite doping was prepared by the sol-gel method.And the samples were analyzed by XRD,TEM and UV-Vis methods.As the target contamination,P-nitrophenol was degraded by TiO2 catalyst.The results show that Zn2+ and Sn4+ composite doping can improve the absorbency from 200 nm to 450 nm,and it causes the red-shift.By irradiation of xenon lamp,the photocatalytic activity is better than that of pure TiO2.
