Abstract Developing overall water splitting non‐noble metal electrocatalysts achieving long‐term stability with high activity at industrial‐grade current density remains challenging. Herein, a self‐reconstruction strategy of Co 9 S 8 ‐Ni 3 2 /NCF is employed to fabricate Ni x 3‐x O 4 ‐Ov‐ in which partial replaced by the structure. The reconstructed ‐Ov can enhance adsorbing ability leached from initial phase compared spinel, exceeding 1000‐h oxygen evolution reaction (OER) and 600‐h 1000 mA cm −2 excellent activity. In situ Raman X‐ray photoelectron spectroscopy (XPS) results indicate that substitution for atoms enhances adsorption capacity on ‐Ov, facilitating formation high‐density 3+ active sites (400) expedited interfacial electron transfer densities. Density functional theory (DFT) calculations reveal stabilizes surface vacancies optimizes energy intermediates, thereby improving both catalytic performance. findings provide new insights into overcoming activity‐stability trade‐off contribute design
