Abstract: The construction of efficient and cost-effective OER electrocatalysts is important for promoting hydrogen production by electrolysis of water. Nitrogen-doped 3D porous carbon materials are prepared by ammonia annealing. Subsequently, NiFeP nanoparticles are loaded on the nitrogen-doped carbon materials to form NiFeP/NC hybrids. Electrochemical tests in alkaline electrolytes show that the overpotential of NiFeP/NC is 241 mV at 10 mA cm −2 . Experiments illustrate that NiFeP/NC follows the LOM pathway for the oxygen evolution reaction. This work provides new ideas for developing high-performance carbon-based OER catalysts based on the LOM pathway, which has great potential for application in the catalytic field.
