Electrochemical Synthesis of Ammonia Using Fe3Mo3N Catalyst and Carbonate-Oxide Composite Electrolyte

International Journal of Electrochemical Science, 2015
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
