Abstract

Abstract:

The polyaniline/polysulfone(PAN/PSF) composite film modified electrodes doped with cerium oxide were prepared by electropolymerization, and then Pt particles were deposited into this composite film to obtain the Pt modified cerium oxide/polyaniline/polysulfone(Pt-CeO2/PAN/PSF) electrodes. Their morphology and chemical component were characterized by field emission scanning electron microscopy(FESEM) and energy dispersive X-ray spectroscopy(EDS), respectively. Cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS) techniques were applied to investigate the electrocatalytic activity of the electrode for methanol oxidation. The results show that the composite film has a bi-layer structure with asymmetrical pores, and platinum and cerium oxide particles are uniformly dispersed in the modified film electrodes. The average size of particles is about 80 nm. The electrode holds higher electrocatalytic activity and better stability for methanol oxidation on the condition of mass ratio between CeO2 and Pt is equal to 7%.

Key words: Pt-CeO2/PAN/PSF electrodes electrode, Catalytic activity, cyclic votammetry, electrochemical impedance spectroscopy
