What an active field! Oxygen tolerance of an in silico-designed bioinspired hydrogen-evolving catalyst in water (PNAS) Certain bacterial enzymes, the diiron hydrogenases, have turnover numbers for hydrogen production from water as large as 104/s. Their much smaller common active site, composed of earth-abundant materials, has a structure that is an attractive starting point for the…
