Ag-doped ZnO nanoparticles (AZNs) were directly synthesized using sol-gel method to embed into polyacrylonitrile (PAN) nanofibers by electrospinning. The synthesized AZNs were optically and structurally characterized by UV-VIS spectroscopy, photoluminescence spectroscopy, high resolution HR-TEM and XRD. The photocatalytic activity of the AZNs was examined by photocatalytic degradation of methylene blue to correlate with their antiviral efficacy in PAN nanofibers fabricated via electrospinning technique. The PAN nanofibers containing AZNs were characterized using SEM and EDS. Finally, antiviral activity of AZNs/PAN nanofibers was investigated by using virus x174 under visible light irradiation. As a result, the antiviral efficacy of nanofibers increased as the concentration of Ag in AZNs increased. The results show that better antiviral efficacy was obtained in AZNs/PAN nanofibers prepared with AZNs of higher photocatalytic performance.
采用溶胶-凝胶法直接合成了掺银氧化锌纳米颗粒（AZNs），并通过静电纺丝将其嵌入聚丙烯腈（PAN）纳米纤维中。通过紫外-可见光谱、光致发光光谱、高分辨率高分辨透射电子显微镜（HR-TEM）和X射线衍射（XRD）对合成的AZNs进行了光学和结构表征。通过亚甲基蓝的光催化降解来检测AZNs的光催化活性，以关联其在通过静电纺丝技术制备的PAN纳米纤维中的抗病毒效果。使用扫描电子显微镜（SEM）和能谱仪（EDS）对含有AZNs的PAN纳米纤维进行了表征。最后，在可见光照射下，使用病毒x174研究了AZNs/PAN纳米纤维的抗病毒活性。结果表明，随着AZNs中银浓度的增加，纳米纤维的抗病毒效果增强。结果表明，用具有更高光催化性能的AZNs制备的AZNs/PAN纳米纤维具有更好的抗病毒效果。
