Summary:Ni2P nanoparticles anchored on MOF-derived Co,N-doped porous carbon polyhedrons (Ni2P/CoN–PCP) were successfully prepared. The Ni2P/CoN–PCP catalyst shows excellent trifunctional electrocatalytic performances for the oxygen reduction, oxygen evolution, and hydrogen evolution reactions, attributed to the synergistic effect between active Ni2P nanoparticles and the CoN–PCP support with rich Co–Nx centres, abundant defects and high conductivity. This work demonstrates a superior low-cost electrocatalyst for potential application in fuel cells and water splitting devices.
