Pd/Multi-walled Carbon Nano-tube Composite Used as Anode Materials for Direct Methanol Fuel Cell
The functionalized multi-walled carbon nano-tubes(MWCNTs) were prepared on Pd nano-particles.The eletrocatalyst was characterized by transmission electron microscopy(TEM),X-ray diffraction(XRD).The catalytic activity for methanol oxidation in alkaline media was studied by cyclic voltammograms(CVs) and chronoamperometry.The results show that Pt nano-particles highly disperse on the MWCNTs surface.The Pd/MWCNTs catalyst exhibites high catalytic activity and stability.The Pd/MWCNTs catalyst has a promising application in alkaline direct methanol fuel cells(DMFC).
