Hydrogen evolution reaction
Hydrogen evolution reaction (HER) is a chemical reaction that yields H2.[1] The conversion of protons to H2 requires reducing equivalents and usually a catalyst. In nature, HER is catalyzed by hydrogenase enzymes. Commercial electrolyzers typically employ platinum metal as the catalyst. HER is useful for producing hydrogen gas, providing a clean-burning fuel.[2] HER, however, can also be an unwelcome side reaction that competes with other reductions such as nitrogen fixation and electrochemical reduction of carbon dioxide.[3]
