A facile template-engaged strategy is developed to synthesize hollow NiFe mixed metal oxyphosphide spheres using different Fe ions (Fe2+ and Fe3+) as modulators. Benefiting from the optimized compositional and structural features, the as-obtained hollow spheres show excellent performance for the oxygen evolution reaction.
