Abstract:

The preparation of electrocatalysts of high performance and low cost is one of the most important subjects in electrocatalysis. The use of glassy carbon (GC) as substrate has been investigated the most extensively[1]. In the present work, the nanostructured material of PtPbSb alloy supported on glassy carbon (PtPbSb/GC) was prepared by electrochemical co-deposition method. The structure and properties of these electrocatalysts were studied through techniques of cyclic voltammertry, X-ray photoelectron spectroscopy (XPS)pl and scanning tunneling microscopy (STM).
