In this study, the synthesis of ammonia (NH3) at ambient pressure using H-2 and N-2 is electrochemically achieved. The conducting and reaction media with molten salt consist of molten hydroxide as NaOH and KOH whereas the reaction temperature is varied in the range of 200 degrees C to 255 degrees C to investigate the impact of temperature on the ammonia production rate and hence performance. The porous nickel mesh electrodes having an area of 100 cm(2) are used as cathode and anode where the supplied electricity is controlled using potentiostat/galvanostat. The maximum faradaic efficiency for ammonia synthesis is found to be 9.3% at 210 degrees C corresponding to 6.53 x 10(-10) mol/s cm(2) ammonia evolution rate at 2 mA/cm(2) current density with nano-Fe3O4 as the catalyst. Furthermore, the applied voltages and applied currents are varied to find the optimum experimental conditions for molten salt electrolyte based electrochemical ammonia synthesis.
