The Haber Bosch industrial NH3 production process has high energy consumption and severe CO2 emission. Electrochemical N-2 reduction is an attractive method for the synthesis of carbon-neutral NH3. However, since an efficient electrocatalyst is required to perform the N-2 reduction reaction (NRR) at room temperature, N-2 activation is a severe challenge. Herein, we report a CeP nanoparticle-reduced graphene oxide (CeP-rGO) hybrid as an effective electrocatalyst for NH3 synthesis. In 0.1 M HCl, CeP-rGO achieves a large NH3 yield of 28.69 mu g h(-1) mg(cat.)(-1) and a high faradaic efficiency of 9.6% at -0.40 V, and it also shows high electrochemical and structural stability. Density functional theory (DFT) calculations show that CeP can efficiently catalyze the synthesis of NH3.
