AB  - Electrochemical nitrogen reduction reaction (NRR) has been considered as a 
      promising alternative to the traditional Haber-Bosch process for the preparation 
      of ammonia (NH(3)) under ambient conditions. The development of cost-effective 
      electrocatalysts with suppressive activity for hydrogen evolution reaction is 
      critical for improving the efficiency of NRR. Herein, oxygen-containing 
      molybdenum carbides (O-MoC) embedded in nitrogen-doped carbon layers (N-doped 
      carbon) can be easily fabricated by pyrolyzing the chelate of dopamine and 
      molybdate. A rate of NH(3) formation of 22.5 mug.h(-1).mg(cat)(-1) is obtained at 
      -0.35 V versus reversible hydrogen electrode with a high faradaic efficiency of 
      25.1% in 0.1 mM HCl + 0.5 M Li(2)SO(4). Notably, the synthesized O-MoC@NC-800 
      also exhibits high selectivity (no formation of hydrazine) and electrochemical 
      stability. The moderate electron structure induced by the interaction between 
      O-MoC and N-doped carbon shells can effectively weaken the activity of hydrogen 
      evolution reaction and increase the faradaic efficiency of NRR. Additionally, by 
      applying the in situ Fourier transform infrared spectroscopy, an associative 
      reaction pathway is proposed on O-MoC@NC-800. This work provides new insights 
      into the rational design of carbon-encapsulated metal nanoparticles as efficient 
      catalysts for NRR at ambient conditions.
