摘　　要：本文以乙酸锌为锌源,聚乙烯吡咯烷酮(PVP)为模板剂,N,N-二甲基甲酰胺(DMF)为溶剂,采用静电纺丝法制备氧化锌纳米纤维.利用X射线衍射仪(XRD)、紫外-可见漫反射光谱(UV Vis DRS)、光催化反应仪(BL-GHX-V)等测试方法来对样品结构和性能进行表征.XRD分析表明,ZnO纳米纤维的衍射峰位置和相对强度与标准卡片PDF#80-0075一致,无杂峰出现,制备得到了纯相的ZnO.以罗丹明B为目标降解物,光照150 min后,ZnO纳米纤维对罗丹明B的降解率为92.8%.In this paper,zinc oxide nanofibers were prepared by electrostatic spinning method using zinc acetate as zinc source,polyvinylpyrrolidone(PVP)as template and N,N-dimethylformamide(DMF)as solvent.The structure and properties of the samples were characterized by X-ray diffraction(XRD),ULTRAVIOLET-visible diffuse reflectance spectroscopy(UV Vis DRS),and photocatalytic reaction apparatus(BL-GHX-V).XRD analysis shows that the diffraction peak position and relati ve strength of ZnO nanofibers are consistent with that of standard PDF#80-0075,and no impurity peak appears.Pure ZnO nanofibers are prepared.Taking rhodamine B(Rh B)as the target degradation material,the degradation rate of RhB by Zn O nanofibers was 92.8%after 150 min of irradiation.
