چکیده انگلیسی
PtFe nanotubes are synthesized by galvanic exchange reactions using Co nanowires as template and reducing agent, followed by mixed with graphene to prepare PtFe nanotubes/graphene hybrid catalyst. The morphology and crystal structure of as-made hybrid are characterized by transmission electron microscope and X-ray diffraction. Its electro-catalytic properties toward methanol oxidation are investigated by cyclic voltammetry and chronoamperometry. The average diameter and wall thickness of the PtFe nanotubes supported on graphene are ca. 50Â nm and 10Â nm, respectively. As an electro-catalyst for methanol electro-oxidation, PtFe nanotubes/graphene catalyst displays higher specific activity and stability than commercial PtRu/C catalyst and PtFe nanoparticles/graphene catalyst.
