Galvanic replacement mediated morphological adjustments boost nanoparticle performance in electrocatalytic alcohol oxidation

Abstract

The PdPtCo core–shell nanostructure, fabricated via galvanic replacement by rapidly incorporating Pd into PtCo nanoalloys at room temperature, excels in alcohol oxidation (AOR). Synergistic effects lower Pt electron density, promoting C–C cleavage, while increased Co coverage reduces CO_ads adsorption, enhancing CO tolerance. This work offers a novel strategy for high-performance AOR catalysts.
