摘要

Cobalt molybdenum nitride (Co3Mo3N) catalyst was synthesised through ammonolysis of the corresponding precursors by flowing pure ammonia gas. The catalyst was characterised by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Ammonia was successfully synthesised from wet hydrogen and dry nitrogen at atmospheric pressure using Co3Mo3N-Ag composite as cathode, Ag-Pd alloy as anode and LiAlO2-(Li/Na/K)(2)CO3 composite as an electrolyte. Ammonia formation was investigated at 400, 425 and 450 degrees C, and the maximum observed ammonia formation rate was 3.27 x 10(-10) mol s(-1) cm(-2) at 450 degrees C when applied at 0.8 V. The catalytic activity of Co3Mo3N for electrochemical ammonia synthesis is lower than that of Pd. The successful synthesis of ammonia demonstrates that LiAlO2-(Li/Na/K)(2)CO3 composite exhibits protonic or/and oxygen ion conduction.
