    In this study, we synthesed two kind of TiO2    nanomaterial (nanoparticles and nanofiber) for photocatalitic     degradation of methyl orange (MO) as pollutant. TiO2    nanoparticles were synthesized by sol-gel technique using     titanium (IV) isopropoxide as precursor. Polyvinyl acetate     (PVAc)/TiO2 hybrid nanofibers were fabricated by     combining sol-gel process with electrospinning technology,     which consisted of PVAc as organic segment and TiO2    as inorganic part. Crystalline phase of TiO2    nanomaterials was investigated by X-ray diffraction (XRD). The     XRD results show that the TiO2 nanomaterials     crystallize in anatase with some rutile phase and these consist     of titanium dioxide nano-crystals. The surface structures of     TiO2 nanomaterials were examined using scanning     electron microscopy (SEM). SEM scanning revealed that the     nanoparticle and nanofibrous structure was formed. Fourier     transform infrared spectroscopy (FTIR) was employed to analyze     the chemical structures of the PVAc/TiO2 hybrid     nanofibers. The FTIR analysis indicated the newly formed     associated hydrogen bond because of the hybrid effect between     PVAc and TiO2 sol. Finally, The photooxidative     decomposition of methylene blue by using the titania     nanomaterials was examined and compared.
