Abstract Construction of heterojunctions is an effective strategy to enhanced electrocatalytic oxygen evolution reaction (OER), but the structural active phases and synergistic mechanism still lack in‐depth understanding. Here, FeOOH/Ni 3 S 2 heterostructure supported on nickel foam (NF) through a two‐step hydrothermal‐chemical etching method reported. In situ Raman spectroscopy study surface reconstruction behaviors /NF indicates that Ni can be rapidly converted NiOOH, accompanied by phase transition from α ‐FeOOH β during OER process. Importantly, deep analysis Ni─O bond reveals FeOOH regulate lattice disorder NiOOH for improved catalytic activity. Density functional theory (DFT) calculations further confirm NiOOH/FeOOH possess strengthened adsorption O‐containing intermediates, as well lower energy barrier toward OER. As result, exhibits promising activity stability in alkaline conditions, requiring overpotential 268 mV @ 100 mA cm −2 long‐term over 200 h at current density . This work provides new perspective understanding heterogeneous electrocatalysts
