Graphical Abstract

Light, polymer, action: A set of water-soluble poly(acrylic acid) catalysts PAA-g-Fe2S2 containing {Fe2S2}, an [FeFe]-hydrogenase active-site mimic, is synthesized. This system, combined with CdSe quantum dots and ascorbic acid, has an exceptional turnover number and initial turnover frequency (27 135 and 3.6 s−1) for the photocatalytic production of H2 in water, which is the highest efficiency to date for [FeFe]-hydrogenase mimics.
