To improve the visible light photocatalytic (PC) activity of TiO₂ photocatalyst, the well-aligned TiO₂ nano-tubes (TiO₂ NTs) were in-situ grown by anodization of Ti foils, and the graphene film was anodic electrodeposited onto the aforementioned TiO₂ NTs to constructed graphene film decorated TiO₂ NTs (GF／TiO₂ NTs) photoelectrode. Apparent morphology, surface composition and light absorption ability of the resulting photoelectrodes were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and UV-visible light diffuse reflection spectroscopy (UV-vis DRS). It was found that the graphene were successfully decorated onto the surface of TiO₂ NTs electrode, and existed as the transparent film. In addition, the light absorption of GF／TiO₂ NTs photoelectrode was greatly red-shifted to visible light region. Furthermore, the methyl blue (MB) was served as the probing molecules, and the effects of deposition voltage and deposition time on the PC performances were mainly investigated. It was found that when the deposition voltage and applied time were +0.8 V and 10 min, respectively, the optimal photodecomposition of MB could be obtained. Under the simulated sunlight irradiation within 120 min, the 65.9％ degradation rate of MB could be achieved, which was 1.35 time larger than that of pristine TiO₂ NTs photoelectrode.
