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.
