Effects of Cl and F Adsorption on Methanol Oxidation on Polycrystalline Platinum Electrode

    Abstract:

    The adsorption of anions on platinum electrode was determined by electrochemical impedance spectroscopy in H2SO4 solution. The results indicate that addition of Cl may increase adsorption capacitance largely, while F has little influence on adsorption capacitance. The results of cyclic voltammetry (CV) show that the methanol oxidation peak current decreases slowly with increase the concentration of F, but drastically with the increase of Cl concentration.
