Abstract:
Hollow CoPt chainlike nanomaterials were synthesized by a galvanic displacement reaction. The morphology, structure, and composition of the nanomaterials were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and electron dispersive X-ray (EDX) analysis. It has found that the hollow CoPt chainlike nanoparticles supported on glassy carbon substrate (CoPt/GC) exhibited enhanced electrocatalytic activity toward methanol oxidation in comparison with commercial Pt/C catalyst (Johnson-Matthey, 20 wt% Pt). The studies demonstrated also that the hollow CoPt chainlike nanomaterials possess a superior electrocatalytic property for CO oxidation than that of Pt/C and bulk Pt. The IR properties of the CoPt nanomaterials were investigated by in situ FTIR reflection spectroscopy employing CO adsorption as probe reaction. It has revealed that the hollow CoPt chainlike nanomaterials present abnormal infrared effects (AIREs).
