Abstract
Solar water splitting has attained much attention in recent years for renewable and clean production of hydrogen from water under irradiation by sunlight. Solar water splitting has been progressively at the forefront of chemical research and also provides a promising path for sustainable hydrogen production. TiO2 has a wide range of applications and is considered as one of the most propitious semiconductors due to its photo-stability, low price and chemical stability. TiO2 nanotubes have been prepared by using electrochemical anodization method followed by organic dye deposited onto the TiO2 nanotubes. rGO-supported TiO2 nanotubes and dye-doped graphene-supported TiO2 nanotubes show more efficient behavior for water splitting as compared to pure TiO2 nanotubes. The surface morphology, elemental composition, structure and size of the nanocrystalline TiO2 nanotubes and dye-doped graphene-supported TiO2 nanotubes were examined by using SEM, XRD, EDX and UV/Visible spectroscopy, respectively. Dye-doped graphene-supported TiO2 nanotubes have been utilized for efficient solar water splitting.
