Electrospinning fabrication and photocatalytic activity of Bi2WO6 nanofibers

Bi 2 WO 6 nanofibers were synthesized by an electrospinning process. The phase, microstructure and photocatalytic performance of the obtained Bi 2 WO 6 photocatalysts were investigated. The XRD patterns and FTIR spectrum suggest that Bi 2 WO 6 nanofibers have the orthorhombic phase. The SEM and TEM images show that Bi 2 WO 6 nanofibers have a rough surface and a large number of hollow caves. The Bi 2 WO 6 hierarchical nanofibers show a high decomposition efficiency of MO under light irradiation. The higher photocatalytic activity of Bi 2 WO 6 nanofibers results from the large specific surface area. The large specific surface area provides more surface active sits and makes an easier charge carrier transport.
