Abstract

Reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. Then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. The Physical morphology of the platinum on reduced graphene oxide film was evaluated by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). The results showed that, Platinum particles were deposited on reduced graphene oxide film. The performance of Pt on reduced graphene oxide for oxygen reduction reaction was considered with linear sweep voltammetry and electrochemical impedance spectroscopy of catalyst in an acidic solution via three electrode configuration cell. The results showed the proper performance of this green synthesized catalyst for oxygen reduction reaction. so this method for catalyst fabrication is a good candidate for the cathode of proton exchange membrane fuel cells.
