Abstract

Abstract

En 中文
• Pt-HEA-6/MWCNTs exhibited high activity, stability, and CO tolerance during MOR. • Reduced Pt-Pt coordination and compressive strain weaken *CO adsorption, promote C-H activation, and enhance MOR performance. • Chemical order engineering optimizes sites, lowers barriers, and curbs metal leaching, enhancing electrocatalytic activity. • Introducing metallic Ru enhances *OH adsorption and accelerates *CO detoxification, thereby freeing more active sites.
