Abstract
Abstract Seawater electrolysis is an appealing route toward sustainable hydrogen production, yet its practical deployment is hindered by severe chloride-induced corrosion and parasitic chlorine oxidation. Here, we report noble metal-doped NiV layered double hydroxides (LDHs) that integrate electronic modulation with a dual chloride confinement mechanism. Ir incorporation simultaneously establishes strong Ir-Cl coordination and dynamically regenerated VO 4 3− layers, producing an adaptive electrostatic shield that effectively suppresses chloride penetration. As a result, Ir-NiV LDH delivers nearly 100% oxygen evolution reaction selectivity and outstanding stability over 2750 h at 500 mA cm −2 . Meanwhile, Ru…
