Novel mix-phase TiO2 nanosheets were successfully synthesized by a facile sol-gel method using graphene oxide (GO) as the sacrifice template for the first time. The SEM, TEM and AFM images revealed that the thickness of mix-phase TiO2 nanosheets was ca. 66 nm, and the TiO2 nanosheets were in a polycrystalline phase and made up of nanoparticles with the diameters of 15-25 nm. In addition, we observed that the proportion of rutile and anatase changed with the amount of tetrabutyltitanate (TBT). The results showed that the sample with 4 mL tetrabutyltitanate (TBT-4) exhibited the highest hydrogen production rate (339 mu mol h(-1)) in all samples, which was 47% higher compared to the bulk sample. It was attributed mainly to the surface phase junction of anatase and rutile and the special morphology of the samples.
