Rational design of efficient Pd-based electrocatalysts is significant for the improvement of their performances for ethanol oxidation reaction (EOR). In this study, core-shell Au@Pd nanodendrites (Au@Pd NDs) were fabricated by a facile and efficient seed-media growth approach at room temperature. The core-shell Au@Pd NDs exhibited better electrocatalytic activity toward EOR in alkaline media, which was 2.34 times higher than that of the commercial Pd/C. The improvement of activity was attributed to the bimetallic synergistic effect and interaction between Pd shell and Au core nanostructure.

Au @ Pd核壳纳米树突对高效乙醇电氧化的催化活性分析

合理设计有效的Pd基电催化剂对于改善乙醇氧化反应（EOR）的性能具有重要意义。在这项研究中，核壳Au @ Pd纳米枝晶（Au @ Pd NDs）是通过在室温下简便而有效的种子培养基生长方法制备的。核-壳型Au @ Pd NDs在碱性介质中对EOR表现出更好的电催化活性，是市售Pd / C的2.34倍。活性的提高归因于双金属的协同作用以及钯壳与金核纳米结构之间的相互作用。
