Homogeneous photocatalytic production of hydrogen from water by a bioinspired [Fe₂S₂] catalyst with high turnover numbers

Abstract

A three-component homogeneous catalyst system, composed of a cyclometalated iridium(III) photosensitizer, a bioinspired diiron complex, and TEA in aqueous acetone, proved to be catalytically active for photoinduced H2 production, with up to 660 turnovers over 8 h of irradiation.
