Using tetrabutyl titanate, hydrofluoric acid and graphite rod as raw materials, the carbon dots with high catalytic activity were loaded on the (001) crystal plane of TiO2 nanosheets by simple hydrothermal method to prepare CDots-(001) TiO2 nanosheets. Through the synergistic effect of the high catalytic activity of the (001) crystal plane and the carbon point, the light absorption, the transport and sepa-ration efficiency of carriers of TiO2 nanosheets improves, thus the hydrogen production performance of the material is effectively improved. The UV-vis DRS, PL, and transient photoresponse analysis results show that the visible light absorption of TiO2 nanosheets with exposed (001) crystal plane enhances after loading with carbon dots, and the separation and transmission rate of photogenerated carriers are accelerated. The photocurrent density of CDots-(001)TiO2 nanosheets is roughly fourth as high as that of TiO2 under intermittent visible light irradiation. The photocatalytic hydrogen production rate of CDots-(001)TiO2 nanosheets is up to 5859 μmol/(h·g), and the quantum efficiency is up to 9.6%.
