Abstract

In this study TiO2 nanotubular fibers were prepared and subsequently loaded with CdS nanoparticles to obtain visible light activate nanofibers with modified structure. Preparation of TiO2 fibers was based on templating method and Liquid phase deposition technique (LPD) with cellulose fibers as templates. Using LPD, thickness of the TiO2 layer could be controlled precisely by adjusting the reaction conditions, therefore after removal of the template, the resulting material has a fibrous structure, mimicking the cellulose fibers shape. CdS nanoparticles were synthesized by thermochemical growth method and attached to TiO2 fibers through impregnation method. The pure composite nanofibers were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and UV-visible spectroscopic techniques. To investigate the photoactivity of CdS/TiO2 fibers, using MB decomposition test under visible light irradiation was studied and compared with that of pure TiO2 nanofibers and CdS nanoparticles. A possible mechanism of sensitization of TiO2 with CdS nanoparticles and visible light MB decomposition was also discussed. Photocatalytic decomposition test under visible light irradiation shows that these novel structures are appropriate for visible photocatalysis applications.
