中文摘要：
采用静电纺丝法制备PVP/Zn（CH3COO）2/Cu（NO3）2复合纤维,经烧结得到ZnO/CuO纳米复合纤维。对烧结前后的纤维形貌、纯度和晶型用热重分析仪（TG）,X射线能谱仪（EDS）,傅里叶红外光谱仪（FTIR）,X射线衍射仪（XRD）和场发射扫描电镜（FE-SEM）来进行表征。用紫外-可见分光光度计（UV-vis）来表征ZnO/CuO纳米复合纤维对亚甲基蓝溶液的光催化降解情况。结果显示：乙酸锌与硝酸铜的质量比为10∶1时,复合纤维在700℃时烧结剩余样品,其光催化性能相对较好。
英文摘要：
PVP/Zn（CH3COO）2/Cu（NO3）2 composite nanofibers are prepared by electrospinning,and ZnO/CuO composite nanofibers are successfully obtained by high temperature sintering of those above composite nanofibers.Field-emission scanning electron microscope（FE-SEM）,thermal gravimetric analysis（TG）,energy dispersive spectroscopy（EDS）,fourier transform infrared spectroscopy（FTIR） and X-ray diffraction（XRD） are used to characterize fibers before and after sintering.The photocatalytic activity of ZnO/CuO composite nanofibers is investigated using ultraviolet–visible Absorbance by following the photodegradation of methylene blue.When the composite fibers of zinc acetate and copper nitrate complex mass ratio being 20∶1 is sintered at 700 ℃,it is found the photocatalytic efficiencies of the remaining sample at this point are proved to be the highest by monitoring the photodegradation of methylene blue.
