Abstract  Pd/Sn graphite electrode had been synthesized by chemical cobalt-plating. The microstructure and composition of modified graphite electrode were analyzed using scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). Cyclic voltammetry and AC impedance were employed to study the electrocatalytic activity of the catalysts. Results show that Pd/Sn were deposited on graphite matrix as spherical particles and has no agglomerate in it. The relationships between peak current density and the square root of scan rate are linear, and the reaction rates of methanol and COads oxidation increase as the potentials increase.
Key words:  inorganic non-metallic materials      alkaline medium      Pd/Sn      cyclic voltammetry      AC impedance
