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.

电镀置换介导的形态调整提高了纳米粒子在电催化酒精氧化中的性能。

PdPtCo核壳纳米结构是在室温下通过电替换将Pd快速加入PtCo纳米合金中制备的，具有优异的醇氧化（AOR）性能。协同效应降低了Pt电子密度，促进了C-C的解理，而Co覆盖率的增加降低了COads的吸附，增强了Co的耐受性。这项工作为高性能AOR催化剂提供了一种新的策略。
