1-Dimensional titanium dioxide (TiO2) nanomaterials including nanotubes and nanofibers were prepared in this study to achieve activation under visible light with novel processing techniques. Nitrogen doped-TiO2 nanotubes (N-TiON) were prepared by anodization followed by plasma treatment, and N-doped TiO2 nanofibers (TiO2/PAN) were prepared by electrospinning with polyacrylonitrile as the template polymer. The photocatalytic efficiency under visible light of the two prepared 1-dimensional TiO2 nanomaterials was investigated with the degradation of benzene, toluene, ethylbenzene, and m-xylene (BTEX), common contaminants found in produced water from oil and gas production activities. By comparing the effectiveness of the as-prepared TiO2 photocatalysts with other available techniques for treatment of produce water for reuse purpose, implications on the potential and limitation of the examined photooxidation processes were discussed.
