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.
