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

Developing highly efficient nonnoble bifunctional electrocatalysts for both the H2 evolution reaction (HER) and O2 (OER) is essential but challenging overall water splitting (OWS). Ni based catalysts are proved as promising candidates splitting, which usually undergo surface reconstruction by transforming into nickel oxyhydroxides active sites. Although evidence suggests that originates from exchange of lattice oxygen with OH- in electrolyte under electric field, modulating remains a great challenge. Herein, we propose an edge sites enrichment strategy to promote phase evolution. The one-step synthesized ultrathin Ni3S2/NiO nanomeshes exhibited porous structure contain abundant in-plane interface Owing unique structure, possessed affinity feature proton OH-, resulting faster Ni3S2 Ni(OH)2 than bulk subsequently converted γ-NiOOH lower adsorption barrier H*. Consequently, outstanding OER activity (300 mV at 200 mA cm−2) unexpected HER (73 10 1.0 M KOH. Remarkably, achieved ultralow voltage 1.41 V cm−2 excellent stability prevailed over most reported catalysts. Moreover, performed yield 900 µmol/h solar-assisted system minimum sales price $1.77/kg, much commercial catalyst ($7.18/kg). This work sets new benchmark monometallic industrial provides insights synthesis 2D nanomeshes.
