Abstract
A method is provided for an electrochemical synthesis of ammonia in alkaline media. The method electrolytically converts Nand Hto NHin an electrochemical cell comprising an anode, a cathode, and an alkaline electrolyte. The method includes exposing an anode to a H-containing fluid, wherein the anode is active toward adsorption and oxidation of H; exposing a cathode to a N-containing fluid, wherein the cathode is active toward adsorption and reduction of Nto form NH; and applying a voltage between the anode and the cathode so as to facilitate adsorption of hydrogen onto the anode and adsorption of nitrogen onto the cathode; wherein the voltage is sufficient to simultaneously oxidize the Hand reduce the N. The electrolytic method is performed with the Hand Npressures from about 10 atmospheres (atm) to about 1 atm; and at temperatures from about 25° C. to about 205° C.
