Preparation and Electrocatalysis Properties of Pt/{[PMo_(12)O_(40)]~(3-)/PAMAM}_n Multilayer Films

YU Yan-fan

Abstract

The novel {[PMo12O40]3-/ PAMAM}n multilayer films were prepared on the GC or ITO electrode surface by the electrochemical scan electrodepositing method,and their homogeneous and uniform traits were verified by cyclic voltammetry. {[PMo12O40]3-/PAMAM}n multilayer films were used as a supporter for electro-deposition of Pt nanoparticles in situ. XPS,SEM analysis revealed that Pt nanoparticles had been loaded on the surface of the {[PMo12O40]3-/PAMAM}n multilayer films in the synthesis process. The as-prepared Pt/{[PMo12O40]3-/PAMAM}n composite films were stable and exhibited good catalytic activities for direct methanol oxidation.
