Ammonia is widely used for the preparation of chemical fertilizers, pharmaceuticals, and synthetic fibers. The main industrial synthesis method to produce ammonia is the Harber-Bosch process, which requires high temperatures (500-600℃) and high pressures to split the inherently strong triple bond of N2. Electrochemical reduction of nitrogen to ammonia provides an alternative strategy to replace the Haber-Bosch process for easy and environment friendliness production of NH3. In this study, we report molybdenum nitride/carbide catalysis for ammonia synthesis using urea-metal chloride in ethanol. Using urea-metal chloride synthesis method provided easy and efficiency catalyst synthesis for nitrogen reduction reaction (NRR). It has proven to be a robust electrochemical catalyst for NRR and achieves an NH3 production rate of 4.824 μmol cm-1h-1 at -0.1 V (vs. RHE). This performance is superior to the electrochemical performance previously reported molybdenum transition metal catalyst for NRR. [1-2] References 1. D.-K. Lee and U. Sim, J. Kor. Electrochem.
