Background Electrocatalytic nitrogen fixation could enhance the sustainability of global ammonia production. However, overcoming the high energy barrier to break the triple bond of dinitrogen (N2) has proved to be a challenge. Electrochemical reduction of nitrate (ERN) is an alternative solution, but ERN currently relies on platinum group metals (PGMs)...

Background Reducing nitrate from water streams is an untapped source of nitrogen that could be used for decentralized ammonia production at ambient conditions for agricultural use with a significantly lower cost. Decentralized production of ammonia in rural areas can minimize environmental impacts of the Haber-Bosch process (including produced ammonia...
