Abstract An efficient and cost-effective oxygen evolution reaction (OER) electrocatalyst is key for electrochemical energy generation storage technologies. Here, the rational design in situ formation of an antiperovskite-based hybrid with a porous conductive Cu 1− x NNi 3− y ( represent defect) core amorphous FeNiCu (oxy)hydroxide shell reported as promising water oxidation electrocatalyst, showing outstanding performance. Benefiting from unique advantage core–shell structure, well synergistic effect Fe, Ni, highly hierarchical catalyst exhibits robust OER performance alkaline environments, outperforming benchmark IrO 2 several aspects. Our findings demonstrate application potential materials field electrocatalysis, which may inspire insights into development novel applications.
