Porous TiO_2/ZnO composite nanofibers have been successfully prepared by electrospinning technique for the first time.It was generated by calcining TiO_2/ZnCl_2/PVP[PVP:polyvinyl pyrrolidone)]nanofibers,which were electrospun from a mixture solution of TiO_2,ZnCl_2 and PVP.Transmission electron microscopy(TEM) and X-ray diffraction(XRD) analyses were used to identify the morphology of the TiO_2/ZnO nanofibers and a formation of inorganic TiO_2/ZnO fibers.The porous structure of the TiO_2/ZnO fibers was characterized by N_2 adsoption/desorption isotherm.Surface photovoltage spectroscopy(SPS) and photocatalytic activity measurements revealed advance properties of the porous TiO_2/ZnO composite nanofibers and the results were compared with pure TiO_2 nanofibers,pure ZnO nanofibers and TiO_2/ZnO nanoparticles.
Porous TiO 2 / ZnO composite nanofibers have been successfully prepared by electrospinning technique for the first time. It was generated by calcining TiO 2 / ZnCl 2 / PVP [PVP: polyvinyl pyrrolidone]] nanofibers, which were electrospun from a mixture solution of TiO 2, ZnCl 2 and PVP . Transmission electron microscopy (TEM) and X-ray diffraction (XRD) analyzes were used to identify the morphology of the TiO 2 / ZnO nanofibers and a formation of inorganic TiO 2 / ZnO fibers. The porous structure of the TiO 2 / ZnO fibers was characterized by N_2 adsoption / desorption isotherm. Surface photovoltage spectroscopy (SPS) and photocatalytic activity measurements revealed advance properties of the porous TiO 2 / ZnO composite nanofibers and the results were compared with pure TiO 2 nanofibers, pure ZnO nanofibers and TiO 2 / ZnO nanoparticles.
