Faraday Discuss. 2019 Jul 04;215:216-226. doi: 10.1039/c8fd00173a.

The efficient reduction of protons by non-noble metals under mild conditions is a challenge for our modern society. Nature utilises hydrogenases, enzymatic machineries that comprise iron- and nickel- containing active sites, to perform the conversion of protons to hydrogen....
