In this study, by examining various growth temperature and time, graphene sheets and CNTs have been grown on the surface of TiO 2 nanotubes to produce TiO 2carbon hybrid material (TNG) using the chemical vapor deposition method. The produced hybrid structures were analyzed with FESEM, EDS, Raman, XRD, and TGA. Then, photoelectrochemical properties of prepared films were evaluated by measurements of the photocurrent density-voltage and photocurrent density-time curves. The TiO 2 nanotube-graphene hybrid material sample (sample TNG 10 ) exhibited enhanced photoelectrochemical water-splitting performances, compared with bare TiO 2 nanotube. The photoelectrochemical results revealed that optimum graphene incorporated into TiO 2 nanotubes played a crucial role. Therefore, this hybrid catalyst could be considered as a potential candidate for industrial water splitting.
