In nature, nitrogen is reduced by nitrogenase enzymes, which contain large metalloproteins and promote a sequence of proton-coupled electron-transfer reactions to accomplish the reduction.

Electrocatalytic nitric oxide reduction reaction (NORR) offers a promising route for sustainable ammonia (NH 3) synthesis and ...

In addition, any unreacted nitrogen and hydrogen are recycled. The reaction is reversible. In a chemical equation, the symbol ⇌ is used instead of an ordinary arrow if the reaction is reversible ...
