Abstract Mesoporous TiO 2 single crystal coated with O vacancies, Ti 3+ and OH groups was synthesized by a simple hydrothermal method. Mesoporous form as the growth of TiO 2 . O vacancies and Ti 3+ form with different origins. According to sample’s morphology, specific surface areas, CO 2 adsorption capacity and photocatalytic activity, OH groups can improve the reaction rate of CO 2 photoreduction, and O vacancies and Ti 3+ can influence the utilization of phtogenerated carriers. The photocatalytic activity reaches an optimal value with the calcination condition change, which adjusts the amount of these chemical composition: OH groups, O vacancies and Ti 3+ .
