Synthesis of Fe:Pt Nanoalloy and Application of it in Preparation of Modified Carbon Paste Electrode in Methanol Oxidation

A catalyst for methanol oxidation, PtCo nano alloy, has been synthesized and its electrochemical activity for methanol oxidation has been investigated. X-ray diffraction depicts a good crystallinity of the supported Pt nanoparticles in the composites and reveals the formation of PtCo alloy .Structural characterizations with transmission electron microscopy (TEM) and X-ray powder diffraction (XRD) revealed that PtCo nanoparticles possess an interesting dendritic morphology with excellent structural continuity and integrity. The results show that the PtCo nano alloy modified carbon paste electrode exhibits large electrochemical capacitance for methanol electrooxidation.
