Electrochemical hydrogen production is considered the most reliable approach to transfer renewable energies chemical energy─namely, hydrogen─for storage, and intensive attention has been directed nonprecious catalyst development for water splitting reactions. Among candidates, metal sulfides have extensively explored as an emerging electrocatalyst material oxygen evolution reaction (OER) in reaction, because of their abundant active centers, good electrical conductivity, high intrinsic activity. By optimizing structure states, some advanced catalysts reported recently, which was instructive inspiring novel development. Herein, recent advances electrocatalytic performance optimization strategies transition-metal sulfide OER are reviewed systematically comprehensively. The fundamental catalytic mechanism key parameters first presented then followed by physicochemical properties sulfides, could be helpful understanding correlation between performance. Importantly, activity boosted general strategies, terms defect/vacancy effect, lattice mismatch, phase engineering, heterostructure, doping mainly discussed this work. challenges opportunities related further materials with long-term durability finally proposed. It can concluded that these regulatory largely improve increasing site exposure reducing energy barrier In addition, problems future improving presented, provides beneficial enlightenment guidance efficient low-cost electrocatalysts future. Hopefully, effort would design preparation OER.

Tuning the electroactive surface species of electrocatalysts remains a significant challenge for achieving highly efficient oxygen evolution reactions. Herein, we propose an innovative in situ leaching strategy, modulated by cationic oxidation, to achieve active self-reconstruction these catalysts. Vanadium is introduced as cation into Ni3S2 and oxidized under low oxidative potential, leading subsequent electrolyte triggering self-reconstruction. The structural from V-Ni3S2 Ni(OH)2 subsequently NiOOH identified operando Raman three-step transition. In contrast, V-free unable bypass thermodynamically predicted nickel oxysulfide products transform NiOOH. As result, self-restructured only needs ultralow overpotential 155 mV at 10 mA cm-2, outperforming many other advanced This work provides new guidelines manipulating modulate

In Situ Raman Study of Surface Reconstruction of FeOOH/Ni₃S₂ Oxygen Evolution Reaction Electrocatalysts

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
