Herein, a surface\u2010engineered electrocatalyst comprising osmium nanoparticles (Os NPs) anchored onto CoFe layered double hydroxide (Os\/CoFe LDH) was prepared. X\u2010ray photoelectron spectroscopy revealed that the incorporated Os NPs stabilized high\u2010valence Co\/Fe species, which preferentially promote OH\n                    <jats:sup>\u2212<\/jats:sup>\n                    adsorption over Cl\n                    <jats:sup>\u2212<\/jats:sup>\n                    and function as the genuine active centers for OER. Furthermore, in situ Raman spectroscopy demonstrates that Os NPs\u00a0anchoring modulates the interfacial water structure, thereby enhancing water adsorption and facilitating seawater OER kinetics. The optimized Os\/CoFe LDH\u201040 achieves an overpotential of only 244\u00a0mV at 10\u00a0mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    in simulated alkaline seawater and operates stably for over 300\u00a0h in an anion exchange membrane electrolyzer at 300\u00a0mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    .
