摘要	Electrochemical N-2 reduction to NH3 has been considered as a promising sustainable and clean process to replace the conventional Haber-Bosch process. However, the development of efficient and stable electrocatalysts with superior activity for the electrochemical N-2 reduction reaction (NRR) remains a great challenge. In this work, a composite of MoS2 nanodots highly dispersed on reduced graphene oxide (MoS2 NDs/RGO) is prepared as an effective catalyst for electrochemical N-2 fixation. Benefiting from the homogeneous dispersion of the MoS2 NDs on RGO and the strong C-S-C bridging bonds between them, this composite can provide abundant active sites and boost the electron transfer in the reaction. As a result, the MoS2 NDs/RGO hybrid achieves a remarkable faradaic efficiency of 27.93% and NH3 yield rate of 16.41 mu g h(-1) mg(cat.)(-1) at ambient conditions, which is much better than the NRR performance achieved by MoS2 nanosheets on reduced graphene oxide (MoS2 NS/RGO). Additionally, the catalyst shows high electrochemical selectivity and stability.
