摘　　要：采用溶胶-凝胶法制备了纳米ZnO及1%、2%Fe/Zr共掺杂量的ZnO,使用扫描电镜对制备的纳米材料进行了形貌观察,采用紫外分光光度计测试了纳米材料的吸收光谱及其对罗丹明B的光催化降解性能。结果表明:随着Fe/Zr共掺杂量的增加,纳米ZnO显示出较明显的团聚倾向,而且颗粒增大;同时发现,在催化时间较短时,掺杂对纳米ZnO降解罗丹明B的影响不明显,但随着催化时间增加,Fe/Zr共掺杂后的降解效果要优于纯纳米ZnO,尤其1%Fe/Zr共掺杂纳米ZnO对有机污染物罗丹明B的综合催化降解性能优势明显,降解效果更好。Nano ZnO and ZnO doped with 1%and 2%Fe/Zr were prepared by sol-gel method.The morphology of the prepared nanomaterials was observed by SEM.The absorption spectra of the nanomaterials and their photocatalytic properties for Rhodamine B were measured by UV spectrophotometer.The results show that with the increase of Fe/Zr co-doping,nano ZnO shows a tendency of agglomeration and the particles increase;At the same time,it is found that the degradation effect of nano ZnO on Rhodamine B is not significantly affected by doping when the catalytic time is short,but with the increase of catalytic time,the degradation effect of Fe/Zr Co-doped nano ZnO is better than that of pure nano ZnO.Especially 1%Fe/Zr Co-doped nano ZnO has obvious comprehensive catalytic degradation performance and better degradation effect on organic pollutant rhodamine B.
