This paper aims to investigate the electro catalytic activities of poly (methylene blue) composite film. Modified graphite electrodes (Ni-Cu / poly methylene blue / graphite electrode) were examined for electro catalytic activities towards the oxidation of methanol in alkaline solutions. Poly methylene blue prepared electrochemically on the graphite electrode. Nickel and Copper ions are then scattered into the polymer film by immersion of the polymeric modified electrode in a stirred solution containing 0.7M NiSO4.6H2O and 0.05M CuSO4.5H2O. The morphologies and elemental ingredients of the film have inspected by scanning electron microscopy. The presence of Nickel and Copper in the composite film was then confirmed by x-ray diffraction Analysis. In cyclic voltammetry studies, in the presence of methanol Ni-Cu / poly methylene blue modified electrode shows a significantly higher response for methanol oxidation. The reaction followed a Cottrellian behavior under the chronoamperometry regime and the diffusion coefficient of methanol was obtained.
