Modified N doped TiO2 Nanotubes with Magnetic y-Fe2O3 as Visible Light Photocatalysts
y-Fe2O3/N-doped TiO2 nanotubes (N-TiO2 NTs) photocatalyst was successfully prepared by a wet chemical method.Visible light responses of this novel catalyst for decomposing methyl orange (MO) in air were also evaluated.It was found that the photocatalytic activity of γ-Fe2O3/N-TiO2 NTs was higher than those of N-doped TiO2 NTs,TiO2 NTs and P25.The characterizations including TEM,EDX and UV/Vis DRS revealed that iron oxide nanoparticles were decorated in/around N-TiO2 NTs and the spectral response was enhanced in visible region.Meanwhile,the catalyst recyeled by external magnetic field showed that its photocatalytic efficiency did not decrease obviously.
