Abstract Acidic seawater electrolysis offers significant advantages in high efficiency and sustainable hydrogen production. However, situ of acidic remains a challenge. Herein, stable efficient catalyst (SPTTPAB/IrO 2 ) is developed by coating iridium oxide (IrO with microporous conjugated organic framework functionalized sulfonate groups (‐SO 3 H) to tackle these challenges. The SPTTPAB/IrO presents ‐SO H concentration 5.62 × 10 −4 mol g −1 micropore below nm numbering 1.026 16 . Molecular dynamics simulations demonstrate that the blocked 98.62% Cl − from reaching catalyst. This structure combines electron conductivity proton H, weakens adsorption, suppresses metal‐chlorine coupling, thus enhancing catalytic activity selectivity. As result, overpotential for oxygen evolution reaction (OER) only 283 mV@10 mA cm −2 , Tafel slope 16.33 mV dec which reduces 13.8% 37.8% compared commercial IrO respectively. Impressively, exhibits outstanding performance, 35.3% improvement over 69 @1.9 V, while degradation rate (0.018 h 24.6% study an innovative solution designing high‐performance electrocatalysts.
