Abstract
Abstract Direct seawater electrolysis is key for achieving sustainable green‐hydrogen production and transitioning toward a decarbonized energy system. However, its performance is limited by significant challenges, mainly catalyst instability, which is caused by excessive reconstruction, low catalytic activity, and aggressive chlorine‐corrosion. Herein, high‐electronegativity F is introduced into NiFe layered double‐hydroxide (F‐NiFe‐LDH) through fluorination engineering to induce electron‐deficient regions around Ni, thus creating abundant intrinsic high‐valence Ni sites. Correspondingly, the features of weak reconstruction accompanied by high stability, chlorophobic surface, and high‐activity lattice oxygen…
