摘要/Abstract

摘要： 利用静电纺丝技术,以聚丙烯腈(PAN)和三氧化二铋为反应物,得到PAN/BiOCl复合纤维,经进一步控温缓慢氧化分解制备BiOCl无机纳米纤维。采用扫描电子显微镜(SEM)、X-射线衍射仪(XRD)、红外光谱仪(IR)和紫外-可见漫反射(UV-vis/DR)等手段对样品的形貌、晶相和光吸收性能进行表征。结果表明:经500 °C高温煅烧后,BiOCl纳米纤维为规则的一维结构,表面分布均匀,直径约为80~140 nm。通过在紫外光照射下降解罗丹明B实验,表明BiOCl纳米纤维具有良好的光催化活性。

关键词: 纳米纤维, 静电纺丝, 光催化降解

Abstract: PAN/BiOCl composite nanofibers were fabricated from solution containing polyacrylonitrile (PAN) and bismuth oxide.Then inorganic nano-fiber BiOCl was prepared with further oxidation and slow decomposition.By means of scanning electron microscopy (SEM),X-ray diffraction (XRD),infrared spectroscopy (IR)and ultraviolet-visible diffuse reflectance (UV-vis/DR) the morphology,crystalline phase and optical absorption properties of the samples were characterized.The results showed that the composite nanofibers were calcined at 500 °Cfor 10 h,BiOCl nanofibers with pure tetragonal phase were successfully obtained.The diameters of the as-fabricated BiOCl nanofibers ranged from 80 to 140 nm.The nanofibers photocatalyst possessed good photocatalytic activity toward decomposing organic dye rhodamine B as well as sedimentation ability.

Key words: nanofibers, electrospinning, photocatalytic degradation
