Abstract Electrochemical seawater splitting faces competing chlorine evolution reactions and corrosion, proposing significant obstacles to commercial applications. In this work, a feasible strategy is developed for the simultaneous oxidation of SO 4 2− CoFe LDH form an intercalation /CoFe LDH, which achieves excellent OER performance (265.2 mV@100 mA cm −2 ) satisfactory stability (1000 h@500 ). The presence found enhance intrinsic activity reduce corrosion tendency LDH. situ Raman selected area electron diffraction results demonstrated that are simultaneously generated inserted into interlayer. DFT calculations further confirmed insertion reduced Cl − adsorption, improved selectivity. Finally, in flow AEM electrolyzer, Pt/C system exhibited voltage only 2.264 V at 500 achieved stable operation natural 150 h. working efficiency as high 55.0% with price per GGE H 2 low $1.211, promising wide range

Abstract The seawater splitting for green hydrogen production is emerging as a key research focus sustainable energy. Nevertheless, the inherent complexity of seawater, with its diverse ion composition – especially chloride ions, calcium and magnesium ions poses significant challenges in catalyst design. Designing highly active electrocatalysts that can resist corrosion during still challenge. This article presents an overview fundamental mechanisms explores issues encountered at both cathode anode electrode. then shifts to chlorine anode, examining recent advances preventing strategies. Notably, these design strategies, such anionic passivation layers, corrosion‐resistant metal doping, physical barrier situ phase transition‐driven desalination, decoupled splitting, are comprehensively investigated, all which aim enhance catalytic stability splitting. review concludes outlook on practical applications producing through

Abstract The main challenge in developing Schottky‐contact OER catalytic devices based on layered double hydroxides (LDHs) is to achieve metal–semiconductor junctions with low contact resistance and high charge transfer capacity. However, due the presence of potential barriers Fermi pinning, conventional Schottky contacts are usually unsatisfactory, resulting poor‐working electrode performance energy consumption. In this study, a new concept “hindrance factor” introduced quantify difficulty electron transfer, low‐hindrance factor formed by strong coupling semiconductor LDH NiMo alloy clusters designed. This interface guides redistribution, optimizes bonding orbital states adsorption sites, enhances targeted OH intermediates. results show that configured NiMo@NiFeCe‐LDH working only needs 1.445 V (vs RHE) drive reaction shows excellent durability 400 h testing. At same time, strategy for screening high‐performance developed. provides bridge studying properties, hybridization, reveals mechanism reducing resistance, has important guiding significance electrocatalysts stability.
