摘要/Abstract

摘要：

采用直接沉淀法对纳米氧化锌做稀土掺杂改性,制备了钕掺杂纳米氧化锌,并采用X射线衍射、扫描电子显微镜、固体荧光光谱等测试手段对产品做了分析与表征,考察掺杂对氧化锌的物相、晶体结构、荧光性质的影响,将其应用于废水中罗丹明B的光催化降解。结果表明：钕掺杂可大幅度提高纳米氧化锌在汞灯照射下的光催化性能。随着掺杂量增加,掺杂氧化锌纳米材料的光催化降解性能逐渐升高,掺加7%（物质的量分数）钕的纳米氧化锌对罗丹明B的去除率可达89.62%。

Abstract:

The antimony-doped nano-zinc oxide was prepared after the nano-zinc oxide was doped with rare earth by direct precipitation method.The products were analyzed and characterized by X-ray diffraction,scanning electron microscopy and solid-state fluorescence spectroscopy.The effect of doping on the phase,crystal structure and fluorescence properties of zinc oxide was investigated,which was applied to the photocatalytic degradation of rhodamine B in wastewater.The results showed that Nd doping could greatly improve the photocatalytic performance of nano-ZnO under mercury lamp irradiation.With the increase of doping amount,the photocatalytic degradation performance of doped ZnO nanomaterials increased gradually.The removal rate of Rhodamine B by 7%（amount-of substance fraction） Nd-doped nano-ZnO was 89.62%.

Key words: ZnO, photocatalytic, doping, Rhodamine B, rare earth Nd
