Abstract

The iron(II) complex bearing the 2,2′:6′,2′′:6′′,2′′′:6′′′,2′′′′-quinquepyridine (qnpy) ligand, [Fe(qnpy)(H2O)2]2+, is a highly efficient and robust catalyst for photocatalytic reduction of CO2to CO in aqueous acetonitrile solution. A turnover number (TON) for CO of up to 14 095 with 98% selectivity can be achieved using Ru(phen)3Cl2(phen = 1,10-phenanthroline) as the photosensitizer and BIH (1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole) as the sacrificial reductant in a CO2-saturated MeCN/H2O (1 : 1, v/v) solution under visible light irradiation. This Fe complex is state-of-the-art for COvisible-light-driven catalysis.
