Industrial NH(3)synthesis mainly relies on the Haber-Bosch process operated under harsh conditions. Ambient electrochemical N(2)reduction offers an eco-friendly and sustainable pathway for NH(3)synthesis, but its implementation depends on efficient electrocatalysts. Here, we report that a Cu3P nanoparticle-reduced graphene oxide (Cu3P-rGO) hybrid serves as an efficient electrocatalyst toward NH(3)synthesis. Tested in 0.1 M HCl, Cu3P-rGO exhibits a large NH(3)yield of 26.38 mu g h(-1)mg(cat.)(-1)and a high faradaic efficiency of 10.11% at -0.45 Vvs.the reversible hydrogen electrode, with high electrochemical stability. Theoretical calculations reveal that Cu3P can efficiently catalyze NH(3)synthesis.
