Nevertheless, its practical implementation is impeded by severe chloride-induced corrosion and the competing chlorine evolution reaction (CER), both of which predominantly affect the anodic oxygen evolution reaction (OER) and consequently deteriorate the overall efficiency and long-term operational stability of the seawater electrolysis system for sustained hydrogen generation. To address these issues, this study introduces a Ni<sub>3</sub>N selective anion-gating interlayer (SAGI) on a nickel foam substrate. This SAGI increases the electron density at the catalyst surface, effectively repelling Cl<sup>−</sup> ions from the nickel foam skeleton while allowing OH<sup>−</sup> ions to access the NiFeAl-LDH catalytic surface. As a result, the electrolyzer requires only 1.92 and 2.12 V to achieve current densities of 400 and 1000 mA cm<sup>−2</sup>, respectively. Moreover, the electrode demonstrates excellent durability, showing only a 5.8% and 13.6% increase in cell voltage after 500 h of continuous operation at 400 mA cm<sup>−2</sup> in simulated and real alkaline seawater, respectively.
