摘要

运用电化学循环伏安、阶跃电位、以及X-光衍射(XRD)和扫描电镜(SEM)等方法,研究了玻碳表面高分散铂电催化剂在不同条件下的结构与性能.结果指出,玻碳表面沉积的高分散铂黑经高温处理后具有一定的择优取向,晶粒尺寸变大,具有更好的稳定性和对乙二醇的电催化活性.

Abstract

The structures and properties of electrocatalyst of dispersed Plutinum(Pt) on glassy carbon(GC) support under different conditions were studied using cyclic voltammetry,potential step technique,x ray diffraction(XRD) and scanning Electron microscopy(SEM). The results indicated that after having been treated in high temperature,the dispersed Pt on GC support was recrystallised with preferented orientation,and the grain of Pt microcrystal become large and regular.It was illustrated that the dispersed Pt on GC support after high temperature treatment exhibited better stability and high activity for ethylene glycol oxidation.
