Preparation and photocatalytic properties of NiO-TiO2 coaxial nanofibers

    Abstract
  • Ti(OC4H9)4/Ni(CH3COO)2·4H2O PVP fibers were prepared by coaxial electrospinning using PVP/Ni(CH3COO)2·4H2O sol as the core and PVP/Ti(OC4H9)4 sol as the shell, and then Ti(OC4H9)4/ Ni(CH3COO)2·4H2O PVP fibers were heated at 550 ℃ for 6 h to obtain NiO-TiO2 coaxial nanofibers. The structure and properties of the NiO-TiO2 coaxial fibers were investigated using XRD, SEM, FTIR and TG. The photocatalytic properties of NiO-TiO2 coaxial nanofibers were studied by the degradation of methylene blue under UV irradiation. In comparing with TiO2 nanofibers, the NiO-TiO2 coaxial nanofibers exhibite higher photocatalytic activity for the degradation of methylene blue, and the catalyst could be used repeatedly.
