Abstract

A novel strategy for obtaining a high dispersion of Pt₃Sn nanoparticles (NPs) on graphene is demonstrated by exploiting the intermediate phase of Sn/graphene nanocomposite as template. The results show that the Pt₃Sn NPs with sizes of approximate 3–4 nm uniformly disperse on graphene surface. Electrochemical studies reveal that the Pt₃Sn/graphene (50%) nanocomposites show excellent electrocatalytic activity toward methanol oxidation compared with commercial Pt/C catalysts.
