Platinum overlaid PdCulr/C: an Improved methanol oxidation elextrocatalyst. international journal of electrochemical science, 8: 6085 - 60931452-3981http://hdl.handle.net/10566/2558A platinum overlaid PdCuIr/C (Pt-PdIrCu/C) anodic catalyst for direct methanol fuel cell was prepared by a two-step reduction method. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results show that the metal nano-particles had a large surface area and even distribution. The Pt mass activity of the catalyst was about 6.6 times larger than that of a Pt/C catalyst and 1.2 times larger than that of a Pt-PdCu/C catalyst. The high electrocatalytic activities could be attributed to the synergistic effect between Pt and PdIrCu.enInternational Journal of Electrochemical Science is an international peer-reviewed and open access journal that publishes original research articles, short communications as well as review articles in the field of electrochemistry.
