Abstract
In this paper the Pt/Polypphenylenediamine Pt/PpPD nanocomposite was synthesized via hydrothermal condition with H2PtCl6 as oxidant The H2PtCl6 is an oxidant in formation process of PpPD and also played a role as the platinum source The synthesis technique of this material is simple and the carrier material is lowcost The spherical Pt nanoparticles which the diameter is about 50 nm are symmetrical dispersed on elliptical PpPD nanoparticles The structure and morphologies of the composite were characterized with IR Raman spectroscopy XRD and scanning electron microscope Electrocatalytic activity measurements shows the Pt/PpPD nanocomposite have good electrochemical performance for methanol fuel cells The origin of good electrochemical performance for methanol of Pt/PpPD colloids is studied The possible formation mechanism involved is also discussed
