| 英文摘要 | 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 has received growing interest. However, the majority of current studies are conducted on acidic or alkaline electrolytes, and research on 2e(-) ORR in neutral NaCl solutions remains rare. Here, a bimetallic Zn-Cd zeolitic imidazolate framework (ZnCd-ZIF) is rationally designed to achieve chloride-resistant 2e(-) ORR catalysis under simulated seawater conditions (pH 7.5, 3.5% Cl-). Experimental results demonstrate that the ZnCd-ZIF catalyst exhibits an exceptional H2O2 selectivity of 70% at 0.3 V-RHE, surpassing monometallic Zn-ZIF (60%) and Cd-ZIF (50%). Notably, H2O2 production reaches 120 mmol g(-1) in a Cl--containing neutral electrolyte, exhibiting strong resistance to structural corrosion and Cl- poisoning. This work not only pioneers an effective strategy for designing ORR catalysts adapted to marine environments but also advances the practical implementation of seawater-based electrochemical H2O2 synthesis. |
