Porous TiO2/ZnO composite nanofibers have been successfully prepared by electrospinning technique for the first time.It was generated by calcining TiO2/ZnCl2/PVP[PVP:poly(vinyi pyrrolidone)]nanofibers,which were electrospun from a mixture solution of TiO2,ZnCl2 and PVE Transmission electron microscopy(TEM)and X-ray diffraction(XRD)analyses were used to identify the morphology of the TiO2/ZnO nanofibers and a formation of inorganic TiO2/ZnO fibers.The porous structure of the TiO2/ZnO fbers was characterized by N2 adsoption/desorption isotherm.Surface photovoltage spectroscopy(SPS)and photo-catalytic activity measurements revealed advance properties of the porous TiO2/ZnO composite nanofibers and the results were compared with pure TiO2 nanofibers,pure ZnO nanofibers and TiO2/ZnO nanoparticles.
