Article Preview

PVP/ZnO-TiO2 composite nanofibers were prepared by Sol-gel processing followed by electrospinning technique using Ti(OC4H9)4 and polyvinglpyrrolidone ( PVP) as starting materials. ZnO-TiO2 nanofibers of 100–200 nm diameter were obtained by high temperature calcinations of the inorganic organic PVP/ZnO-TiO2 composite fibers.The materials were characterized by differential scanning calorimetry thermogravimetric analysis (DSC- TGA) , Fourier transform infrared (FT-IR),and scanning electron microscopy (SEM). The process of the photocatalytic degradation of methylene blue using ZnO-TiO2 nanofiber as catalyst was investigated.The results show that the ZnO-TiO2 nanofiber dopped 3% ZnO has better photocatalytic activity for methylene blue degradation, the degradation rate of methylene blue solution reached 99% under sunshine for 6 h., and it’s still 95% after eight times reuse.
