Manganese dioxide modified reduced graphene oxide supported Pd nanoparticles (Pd/MnO2-RGO) were prepared facilely by a chemical approach. The as-prepared materials were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The electrocatalytic behavior of the Pd/MnO2-RGO for methanol oxidation was studied using cyclic voltammetry and chronoamperometry. The results indicate that the Pd/MnO2-RGO nanocomposites exhibit higher catalytic activity and better stability than Pd/RGO. (C) 2012 Elsevier B.V. All rights reserved.
