　　This paper reports an approach to prepare bimetallic Pt-M (M =Fe,Co,and Ni) nanoalloys as electrocatalysts and examines their electrochemical activities in 1 M sulfuric acid.The approach consists of chemical oxidation of carbon nanotubes (CNTs),two-step refluxing,and subsequent thermal reduction in hydrogen atmosphere.Three bimetallic pairs of Pt-M catalysts are found to well deposit onto CNT surface,forming Pt-M/CNT composites.
