The electrocatalytic process of water splitting offers a promising approach to produce sustainable hydrogen. However, the slow kinetics oxygen evolution reaction (OER) presents notable challenge, especially in acidic environment proton exchange membrane (PEM) systems. Despite extensive progress made catalyst development for hydrogen production through electrolysis last century, significant advancements have been accomplished. quest OER catalysts that possess both high activity and stability, while also being affordable, continues be challenging. Currently, Ru/Ir-based electrocatalysts are only practical anode available. Therefore, it is crucial explore feasible strategies enhance performance longevity catalysts. This review comprehensive assessment obstacles prospective Additionally, underscores areas research concentration, providing valuable perspectives future endeavors development.

Abstract The exploitation of highly activity oxygen evolution reaction (OER) electrocatalysts is critical for the application electrocatalytic water splitting. Triggering lattice mechanism (LOM) expected to provide a promising pathway overcome sluggish OER kinetics, however, effectively enhancing involvement remains challenging. In this study, fabrication B, Fe co‐doped CoP (B, Fe─CoP) nanofibers reported, which serve as efficient electrocatalyst through phosphorization and boronation treatment Fe‐doped Co 3 O 4 nanofibers. Experimental results combined with theoretical calculations reveal that simultaneous incorporation both B can more trigger participation in CoFe oxyhydroxides reconstructed from Fe─CoP compared incorporating only or Fe. Therefore, optimized exhibit superb low overpotentials 361 376 mV at 1000 mA cm −2 alkaline freshwater natural seawater, respectively. present work provides significant guidelines innovative design concepts development following LOM pathway.

Abstract Single‐atom catalysts (SACs) are demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs still early stages of conversion, problems like agglomeration low conversion efficiency hampering their practical applications. Substantial research focus on support modifications, which vital SAC stability due intimate relationship between atoms support. In this review, category supports variety surface engineering strategies employed SA systems summarized, including site (heteroatom doping, vacancy introducing, groups grafting, coordination tunning) structure (size/morphology control, cocatalyst deposition, facet engineering, crystallinity control). Also, merits single‐atom systematically introduced. Highlights comprehensive summary discussions utilization surface‐engineered diversified applications photocatalysis, electrocatalysis, thermocatalysis, devices. At end potential obstacles using field discussed. This review aims guide rational design manipulation target‐specific capitalizing characteristic benefits engineering.

Abstract Sustaining the steady state for highly active non‐stoichiometric iridium (Ir)‐based oxide (IrO x ) at low Ir loading remains challenging primarily due to continuous oxidation and sequent dissolution of sites during oxygen evolution reaction (OER). In this context, a new iridium–cerium (Ce) substitution solid solution (SSO) has been developed, featuring uniformly dispersed atoms within Ce dioxide (CeO 2 matrix as electron buffer, which delivers remarkable acidic OER catalytic activity enhanced stability. The electron‐buffering capacity CeO facilitates charge transfer toward atoms, leading abundant low‐valence effectively prevent their dissolution. As result, Ir─Ce SSO demonstrates an overpotential merely 238 mV@10 mA cm −2 . Proton exchange membrane water electrolyzer employing 396 µg operates consistently over 100 h@500 Density functional theory (DFT) calculations corroborate that effect enriches density III substantially increases energy barrier atoms. This study presents viable approach addressing issues instability efficiency in Ir‐based electrocatalysts electrolysis.
