Abstract

γ-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 recycled by external magnetic field showed that its photocatalytic efficiency did not decrease obviously.
