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