Abstract
Systems and methods for electrochemical ammonia synthesis comprise electrolytes which have greater efficiency than water, thus leading to cost reductions; and/or cathode catalysts which have lower costs and higher efficiencies in comparison to the iron/nickel catalysts noted above. The electrolyte may be composed primarily of a combination of non-aqueous hydrogen bond donors and acceptors, with high nitrogen solubility and high conductivity. The cathode catalyst may be composed of either a manganese-doped oxide or carbonate material or a two-dimensional carbide or nitride material.
