Hierarchical Ag3PO4/TiO2 nanocomposite fibers were prepared by combining electrospinning technique and hydro-thermal growth method. As-synthesized samples were characterized by using field-emission scanning electron microscopy (FE-SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), Photoluminescence (PL), and Fourier transform infra-red (FT-IR) spectroscopy. The FE-SEM image revealed a uniform decoration of Ag3PO4 nanoparticles without aggregation on primary TiO2 nanofibers. The photocatalytic and antibacterial studies were performed and results were shown that the Ag3PO4/TiO2 nanocomposite fibers show an enhanced photocatalytic and antibacterial activity toward the degradation of dye methylene blue and bacteria (Escherichia coli, Staphylococcus aureus) respectively. Our results can provide new insights of Ag3PO4/TiO2 nanocomposite fibers for the potential applications in antibacterial and waste water treatment.
通过结合静电纺丝技术和水热生长法制备了分级结构的Ag3PO4/TiO2纳米复合纤维。采用场发射扫描电子显微镜（FE-SEM）、透射电子显微镜（TEM）、X射线衍射（XRD）、光致发光（PL）和傅里叶变换红外（FT-IR）光谱对合成的样品进行了表征。FE-SEM图像显示Ag3PO4纳米颗粒均匀地修饰在初级TiO2纳米纤维上，没有聚集。进行了光催化和抗菌研究，结果表明Ag3PO4/TiO2纳米复合纤维分别对染料亚甲基蓝的降解和细菌（大肠杆菌、金黄色葡萄球菌）表现出增强的光催化和抗菌活性。我们的结果可为Ag3PO4/TiO2纳米复合纤维在抗菌和废水处理中的潜在应用提供新的见解。
