Tóm tắt

Designing active and cost-effective catalysts for acidic oxygen evolution reaction (OER) is critically important for improving proton exchange membrane water electrolyzers (PEMWEs) used in hydrogen production. In this study, we introduce a rapid and straightforward method to synthesize a quinary high-entropy ruthenium-based alloy (RuMnFeMoCo) for acidic OER. This iridium-free catalyst demonstrates a low overpotential of 170 mV and exceptional stability, enduring a 1000-hour durability test at 10 mA cm
