Ammonia production method

Abstract

The present invention discloses a green electrochemical ammonia production method, comprising a reduction cell and an oxidation cell separated by a proton-conductive / exchange membrane. The method employs an electrolyte containing lithium salts, aromatic mediators, and organic solvents to achieve an efficient conversion of nitrogen to ammonia under ambient temperature and pressure. At the cathode, lithium deposition and nitrogen activation occur, generating lithium nitride via the aromatic mediator, which is subsequently protonated to release ammonia. At the anode, a hydrogen oxidation reaction provides a continuous and stable proton source. The invention offers high selectivity, energy efficiency, and modular scalability, serving as a sustainable alternative to the conventional energy-intensive Haber–Bosch process, and is applicable to green processes for ammonia fuels, fertilizers, and hydrogen storage carriers.
