BiOCl纳米纤维制备及光催化性能研究

Abstract

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
