Visible light driven photocatalytic CO2 conversion has been investigated using abundant metal complexes catalystfac-[Mn(phen)(CO)(3)Br] and photosensitizer ZnTPP, which efficiently produced carbon monoxide and formic acid in an aqueous acetonitrile solution. The photochemical and electrochemical properties of the catalysis system proved the good ability of the light utilization and the reduction. During the 180-min irradiation experiments with the Mn/Zn ratio of 2:1, the TONs reached 64 for the CO formation and 16 for the formic acid formation, respectively. An integrated mechanism was proposed for the CO2 reduction in this system. This photocatalyst system not only shows environmental friendly and sustainability, but also retains the product selectivity in the CO2 photoreduction system. (C) 2016 Elsevier B.V.
