The nitrogen reduction reaction (NRR) is a key step in electrochemical nitrogen fixation and exploring high-performance electrocatalysts is of paramount significance for achieving the desired NRR efficiency. Herein, we demonstrate that bimetallic MnMoO(4)can be a highly active and durable NRR catalyst. The developed MnMoO(4)nanorods-reduced graphene oxide presented a favorable combination of both high NH(3)yield (60.3 mu g h(-1)mg(-1)) and high faradaic efficiency (14.7%), surpassing nearly all of the previously reported Mn and Mo-based NRR catalysts. Theoretical calculations revealed that the surface-terminated Mn and Mo atoms functioned as dual-active-centers to synergistically boost the NRR and suppress the adverse hydrogen evolution.
