Abstract

The {H3[PMo12O40]/Pt/PAMAM}composite film was prepared on glassy carbon electrode(GCE) by cyclic voltammetry scanning.The film and the electrocatalystic activity toward methanol were characterized by X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM),energy disperse spectroscopy(EDS),atomic force microscopy(AFM) and cyclic voltammetry(CV).The result shows that the Pt nanoparticles are well dispersed on the PAMAM film,and the adding of H3[PMo12O40] on the surface of Pt nanoparticles can improve the electrocatalytic activity toward methanol oxidation.
