| Summary: | A self-supported electrode was designed and prepared for the first time with CeO2 nanoparticles decorated on porous Ni–Fe bimetallic phosphide nanosheets, which were grown on high-conductivity Ni foam. Owing to the strong electronic interactions between the heterostructure interfaces and the introduction of oxygen vacancies, such an electrode displays outstanding oxygen evolution reaction performance with an overpotential of 188 mV at 10 mA cm–2 and the electrolyzer using the electrode as both cathode and anode exhibits a cell voltage of 1.54 V at 10 mA cm–2. |
