Zinc oxide (ZnO) nanostructures have received widespread attention due to their unique structure and broad application possibilities, but high preparation costs and agglomeration limit their usage. In this article, low‐cost and environmentally friendly cellulose and ZnCl₂ are used to synthesize ZnO nanoparticles (ZnO NPs). Subsequently, multifunctional ZnO/polyacrylonitrile hybrid nanofiber mats (ZnO/PAN@NFMs) with mechanical stability suitable for large‐scale application are prepared via solution blow‐spinning. The synthesized ZnO/PAN@NFMs exhibit higher photodegradation of organic dyes than earlier reported semiconductors and good recycling performance with an organic dye degradation above 94%–98% after five cycles, which is ascribed to fixation of the ZnO NPs in the nanofibers. In addition, the inhibition rate for Escherichia coli and Staphylococcus aureus is above 99.9% and the bacteriostatic rate against E. coli remains as high as 99% after 10 cycles. From these properties, the synthesized composite ZnO/PAN@NFMs are promising for wastewater cleaning and antibacterial fabrics.

吹纺制备具有光催化活性和抗菌性能的3D卷曲ZnO / PAN杂化纳米纤维垫

氧化锌（ZnO）纳米结构由于其独特的结构和广泛的应用可能性而受到了广泛的关注，但是高制备成本和结块限制了它们的使用。在本文中，介绍了低成本且环保的纤维素和ZnCl ₂用于合成ZnO纳米粒子（ZnO NPs）。随后，通过溶液纺丝制备了具有适合大型应用的机械稳定性的多功能ZnO /聚丙烯腈杂化纳米纤维毡（ZnO / PAN @ NFMs）。合成的ZnO / PAN @ NFMs与早期报道的半导体相比，表现出更高的有机染料光降解性和良好的回收性能，经过五个循环后有机染料的降解率超过94％–98％，这归因于ZnO NPs在纳米纤维中的固定。另外，对大肠杆菌和金黄色葡萄球菌的抑制率在99.9％以上，对大肠杆菌的抑菌率高。10个周期后仍高达99％。从这些特性来看，合成的ZnO / PAN @ NFMs复合材料有望用于废水清洁和抗菌织物。
