Abstract
Pt/Ni heterostructure nanowires were fabricated by electrochemical deposition method with the help of anodic aluminum oxide (AAO) template. The morphology and structure of the nanowires were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Then, the composite of Pt/Ni nanowires and nafion were employed to modify a GC electrode. The activity and stability of this electrode to the methanol oxidation were evaluated by cyclic voltammetry and chronoamperograms methods. The results indicated that Pt/Ni heterostructure nanowires were a promising new class of catalyst for methanol oxidation and for direct methanol fuel cell applications.
