title: Photocatalytic Reduction of Low Concentration of CO2.
abstract: A novel molecular photocatalytic system with not only high reduction ability of CO2but also high capture ability of CO2has been developed using a Ru(II)-Re(I) dinuclear complex as a photocatalyst. By using this photocatalytic system, CO2of 10% concentration could be selectively converted to CO with almost same photocatalysis to that under a pure CO2atmosphere (TONCO> 1000, ΦCO> 0.4). Even 0.5% concentration of CO2was reduced with 60% initial efficiency of CO formation by using the same system compared to that using pure CO2(TONCO> 200). The Re(I) catalyst unit in the photocatalyst can efficiently capture CO2, which proceeds CO2insertion to the Re-O bond, and then reduce the captured CO2by using an electron supplied from the photochemically reduced Ru photosensitizer unit.
