Abstract
One-dimensional TiO2/SiO2 core-shell nanofibers were fabricated using a single-nozzle co-electrospinning process with phase-separated, mixed polymer composite solution. The core and shell were composed of Polyvinylpyrrolidone (PVP) and Polyacrylonitrile (PAN) polymers with uniform distribution of TiO2 and SiO2 nanoparticles (NPs), respectively. The NPs were synthesized via sol-gel reaction, simultaneously, in the respectivepolymersolutions. ThemorphologiesandstructuresofthefabricatedTiO2/SiO2 core-shell nanofibers were investigated by XRD, FTIR, SEM, EDS, and TEM images. The influences of different amounts of TiO2 and SiO2 precursors on the photocatalytic and UVshielding performance of TiO2/SiO2 core-shell nanofibers were studied. Photocatalytic activity of the nanofibers was evaluated by observing photo-degradation of Methyl Orange (MO) aqueous solution under irradiation of ultraviolet (UV) light. Our results for the TiO2/SiO2 core-shell nanofibers indicate good potential for superior applications in photocatalytic and UV shielding devices.
