Abstract

Abstract : [Fe(qnpy)(H2 O)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)3 Cl2 as photosensitizer and BIH as sacrificial reductant. Abstract : The iron(ii ) complex bearing the 2, 2′:6′, 2′′:6′′, 2′′′:6′′′, 2′′′′-quinquepyridine (qnpy) ligand, [Fe(qnpy)(H2 O)2 ] 2+, is a highly efficient and robust catalyst for photocatalytic reduction of CO2 to 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)3 Cl2 (phen = 1, 10-phenanthroline) as the photosensitizer and BIH (1, 3-dimethyl-2-phenyl-2, 3-dihydro-1 H -benzo[ d ]imidazole) as the sacrificial reductant in a CO2 -saturated MeCN/H2 O (1 : 1, v/v) solution under visible light irradiation. This Fe complex is state-of-the-art for CO2 visible-light-driven catalysis.
