Abstract Oxygen evolution reaction (OER) is the anodic half‐reaction for crucial energy devices, such as water electrolysis, metal–air battery, and electrochemical CO 2 reduction. Fe‐based materials are recognized one of most promising electrocatalysts OER because its extremely low price high activity. In particular, iron oxyhydroxide (FeOOH) not only highly active toward OER, but also widely accepted true species plenty converted into FeOOH during test. Herein, recent advances FeOOH‐based nano‐structure application in reviewed. The relationship between structure catalytic performance, followed by introduction current strategies enhancing activity (i.e., crystalline phase engineering, element doping, construction hybrid materials) mainly focused. Finally, a summary perspective about remaining challenges future opportunities this area further design provided.

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 .
