Oxygen tolerance of a H2-evolving catalyst [Chemistry]

Oxygen tolerance of a H2-evolving catalyst [Chemistry]: 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 design of a practical catalyst for electrocatalytic or solar photocatalytic hydrogen...
