Electrochemical synthesis of ammonia from water and nitrogen at atmospheric pressure could be an alternative to the current ammonia synthesis process (i.e. Harbor-Bosch) and solve the inherent problems of the process including its high energy consumption and greenhouse gas emission. This study reports electrochemical ammonia synthesis from water and nitrogen in molten salts at atmospheric pressure and temperatures exceeding 623K. Modifications on surface materials of the nitrogen activation electrode were made, tested, and their ammonia synthesis rates were compared.
