The biphases TiO2 nanosheet [anatase and TiO2(B)] was prepared by a solvothermal method, and characterized by FESEM, TEM, XRD, HRTEM, Raman spectrum, UV-Vis DRS and N-2 adsorption-desorption. The photocatalytic performance of prepared samples was evaluated by reduction of CO2. The results revealed that the catalyst possessed a high performance of reduction CO2 to methanol. The concentration of catalyst was a crucial factor for the yield of methanol. The possible reason for high photocatalytic activity was forming a heterojunction between two crystal phases, which can promote the separation of electron-hole pairs and prolong it's lifetime.
