Abstract

CuPt nanodendrites have special electrocatalytic performance due to their unique morphologies and structures. In this work, we report a facile and one-pot synthesis of highly branched and dispersed CuPt nanodendrites with a size of about 22 nm and Pt/Cu ratio of 2 : 1. X-ray photoelectron spectra indicate a Pt-rich surface of the prepared CuPt nanodendrites. The combination of a highly branched structure with a Pt-rich shell would be very beneficial for catalytic properties, which was confirmed by electrochemical tests towards MOR. A systematic study on morphology evolution of the products and understanding of their growth mechanism was carried out using the effects of reaction time and reducing agents.

摘要

由于其独特的形貌和结构，铜铂纳米枝晶具有特殊的电催化性能。在本工作中，我们报道了一种简便的一锅法合成高度分支且分散的铜铂纳米枝晶，其尺寸约为22纳米，铂/铜比例为2∶1。X射线光电子能谱表明所制备的铜铂纳米枝晶表面富含铂。高度分支结构与富铂壳层的结合对催化性能非常有利，这通过对甲醇氧化反应的电化学测试得到了证实。利用反应时间和还原剂的影响，对产物的形貌演变及其生长机理进行了系统研究。
