•The film of POMs and TiO2 nanotubes was prepared by electrodeposition.•The photocatalytic activity of the composite film for nitrobenzene was investigated.•The composite film showed higher photocatalytic activity than pure TiO2 nanotubes.•The introduction of POMs into TiO2 could retard electron–hole recombination.
The composite film based on polyoxometalates (POMs)-modified TiO2 nanotubes was prepared by electrodeposition method for the photocatalytic degradation of nitrobenzene. The composite film was characterized by field-emission scanning electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy, which indicated that the POMs were well introduced into the TiO2 nanotubes. Furthermore, the photocatalytic properties of the TiO2 nanotubes and POMs-modified TiO2 nanotubes were evaluated by the decomposition of nitrobenzene. POMs-modified TiO2 nanotubes showed much higher photocatalytic activity than pure TiO2 nanotubes. These results provide a promising route to effectively photocatalytic degradation of nitrobenzene by POMs-modified TiO2 nanotubes.
