       We report the development of MOF-derived nitrogen-doped carbon/ Co3O4 nanocomposites (Co3O4@NCs) with core?shell structures as an efficient electrocatalyst for the artificial nitrogen fixation at room temperature and atmospheric pressure in 0.05 M H2SO4. It exhibits a high NH3 yield of 42.58 μg h?1 mgcat. ?1 and a faradaic efficiency of 8.5% at ?0.2 V versus reversible hydrogen electrode. Experimental results show that the great N2 reduction reaction performance of  Co3O4@NCs originates from the synergistic effects of N-doped carbon and Co3O4 with significant oxygen vacancy. In addition, we speculate that the core?shell structure can further enhance the electrochemical activity for producing NH3.
