Abstract

Iron molybdenum nitride catalyst (Fe3Mo3N) was synthesised via a temperature-programmed reduction (TPR) of the corresponding precursor by flowing pure ammonia gas. The catalyst was characterised by x-ray diffraction (XRD) and scanning electron microscopy (SEM). Ammonia was successfully synthesised for the first time from hydrogen and nitrogen at atmospheric pressure using
Fe3Mo3N-Ag composite as cathode, Ag-Pd alloy as anode and LiAlO2-carbonate composite as solid electrolyte. Ammonia formation was observed at three
different temperatures 400, 425 and 450 ºC and the maximum rate of ammonia production was up to 1.88 × 10-10 mol s-1cm -2 at 425 ºC and 0.8 V. This
experiment indicates that metal nitrides can be used as ammonia synthesis catalysts in theelectrochemical synthesis process.
