Marine biofouling causes significant economic losses, and conventional antifouling methods are often associated with environmental pollution. Hydrogen peroxide (H2O2), as a clean energy source, has gained increasing attention in recent years. Meanwhile, electrocatalytic 2e− oxygen reduction reaction (ORR) for H2O2 production received growing interest. However, the majority of current studies conducted on acidic or alkaline electrolytes, research ORR neutral NaCl solutions remains rare. Here, bimetallic Zn-Cd zeolitic imidazolate framework (ZnCd-ZIF) is rationally designed to achieve chloride-resistant catalysis under simulated seawater conditions (pH 7.5, 3.5% Cl−). Experimental results demonstrate that ZnCd-ZIF catalyst exhibits an exceptional selectivity 70% at 0.3 VRHE, surpassing monometallic Zn-ZIF (60%) Cd-ZIF (50%). Notably, reaches 120 mmol g−1 Cl−-containing electrolyte, exhibiting strong resistance structural corrosion Cl− poisoning. This work not only pioneers effective strategy designing catalysts adapted marine environments but also advances practical implementation seawater-based electrochemical synthesis.

A 2,3‐diaminonaphthalene (DAN) 1,3,5‐triformylphloroglucinol (TP) β‐ketoenamine‐linked covalent organic polymer with naphthalene‐quinone electron donor (D)–acceptor (A) structure (DAN‐TP‐CKP) was synthesized using a one‐pot method. It exhibited high H 2 O production rate of 1120 μmol g cat −1 h in ‐saturated water under visible light, together better durability. The efficiency is attributed to its crystalline framework, large specific surface area (212 m ), strong visible‐light absorption, and efficient charge separation properties arising from dense D–A structures. two‐step single‐electron oxygen reduction reaction pathway probable four‐step mechanism further elucidates generation process. This work highlights D–A‐type naphthalene–quinone metal‐free photocatalysts durable photosynthesis performance.
