Abstract: Poly(acrylonitrile) (PAN) nanofibers containing different amounts of titanium dioxide (TiO2) have been prepared by electrospinning technique. Photocatalytic activity of these electrospun PAN/TiO2 nanofibers and the effect of TiO2 content on the photocatalytic efficiency of PAN/TiO2 nanofibers have been evaluated by monitoring the photodecomposition of fluorescein dye, rhodamine B and methylene blue under UV irradiation with respect to irradiation time. Moreover, the effect of hydrogen peroxide (H2O2) on the photocatalytic behavior of PAN/TiO2 nanofibers has also been investigated. The results showed that PAN/TiO2 nanofibers are effective photocatalyst and their photocatalytic efficiency increases with the increase of TiO2 content in the PAN/TiO2 nanofibers. It is also observed that the presence of H2O2 significantly enhances the photocatalytic ability of PAN/TiO2 nanofibers. The morphology and the photocatalytic behavior of the PAN/TiO2 nanofibers containing different amounts of TiO2 nanoparticles have been investigated by field-emission scanning electron microscopy (FE-SEM) and UV/Visible spectroscopy, respectively.
