Electrochemical reduction is an eco-friendly alternative for energy-saving artificial N-2 fixation. The development of this process requires efficient N-2 reduction reaction (NRR) electrocatalysts to overcome the challenge with N-2 activation. We show that a Cr2O3 nanoparticle-reduced graphene oxide hybrid (Cr2O3-rGO) is as an outstanding catalyst for electrochemical N-2-to-NH3 conversion under ambient conditions. In 0.1 M HCl, Cr2O3-rGO achieves a high NH3 yield of 33.3 mu g h(-1) mg (-1)(cat). at -0.7 V vs RHE and a high Faradaic efficiency of 7.33% at -0.6 V vs RHE, with excellent selectivity for NH3 synthesis and stability. Density functional theory calculations were executed to gain further insight into the mechanisms.
