Nanocomposite Graphene-Based Material for Fuel Cell Applications

Abstract

Cobalt and nickel oxides-graphene nanocomposites have been prepared by a simple chemical route. The structure, morphology and properties were characterized using X-ray diffraction (XRD) and Transmission Electron Microscope (TEM). The electrocatalytic activity for the methanol oxidation reaction in acidic medium of these nanocomposites compared to platinum has been confirmed using cyclic voltammetry technique.
