High-Turnover Photochemical Hydrogen Production Catalyzed by a Model Complex of the [FeFe]-Hydrogenase Active Site

Lifting the diiron curtain: 200 equivalents of H2 per catalyst at a maximum turnover rate of 3.7 H2 per minute can be obtained in a light-driven proton reduction process in near-neutral H2O/DMF (pH 5.5) by using an [FeFe]-hydrogenase active-site model complex as the catalyst (see scheme).
