Trinuclear Re(i)-rings were applied as redox photosensitizers in visible light-driven CO2 reduction in tandem with various catalysts, i.e., Re(i)-, Ru(ii)- and Mn(i)-diimine metal complex. The quantum yields for the Ru(ii) and Mn(i) catalysts were the among highest reported.
A hybrid photocatalytic system consisting of a Ru(ii) binuclear complex and Ag-loaded TaON can reduce CO2 to HCOOH by visible light irradiation even in aqueous solution (TONHCOOH = 750, ΦHCOOH = 0.48%).
A visible-light-driven earth-abundant photocatalytic system for CO2 reduction using an iron catalyst and a copper photosensitizer produces CO as a main product (TONCO = 565) with a high selectivity over H2 production (SelCO2 = 84%).
[Fe(qnpy)(H2O)2]2+ is a highly efficient and robust catalyst for visible-light-driven reduction of CO2 to CO, with a TON for CO of up to 14 095 and selectivity of 98% using Ru(phen)3Cl2 as photosensitizer and BIH as sacrificial reductant.
Even in an aqueous solution, a Ru(ii)–Re(i) supramolecular photocatalyst worked well for CO2 reduction. A water-soluble reductant BI(CO2−)H should be useful for evaluation of the real abilities of various photocatalytic systems.
A discrete metallo–supramolecular assembly composed of six iron(II) cations and twelve redox–active terpyridine fragments has been developed for highly efficient visible–light–driven reduction of CO2 to CO with a TON of...
