摘　　要：To develop highly efficient electrochemical catalysts for N2 fixation is important to sustainable ambient NH_(3) production through the N_(2) reduction reaction(NRR).Herein,we demonstrate the development of vanadium phosphide nanoparticle on V foil as a high-efficiency and stable catalyst for ambient NH3 production with excellent selectivity.The high Faradaic efficiency of 22%with a large NH3 yield of 8.35×10^(−11) mol·s^(−1)·cm^(−2)was obtained at 0 V vs.the reversible hydrogen electrode in acid solution,superior to all previously studied V-based NRR catalysts.Density functional theory calculations are also utilized to have an insight into the catalytic mechanism.
