Electrooxidation for Methanol on Pd Nanoparticles Modified Electrodes in Alkaline Medium

Abstract:

In this paper, Palladium nanoparticles were electrodeposited on the surface of glassy carbon electrodes by more circles cyclic voltammetry method and Palladium nanoparticles modified electrode (Pd/GCE) was obtained. Morphology and crystal structure of nanoparticles were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The performance and electrochemical process of catalytic oxidation methanol were measured and analyzed by cyclic voltammetry (CV), chronoamperometric curves (i-t) and alternating current impedance spectra (AC impedance) in KOH solution. The results showed that catalytic activity of Pd nanoparticles modified electrode for methanol was over 30 times higher than that of the plate Pd electrode, and catalytic performance was good. In addition, the catalytic oxidation was mainly diffusion-controlled process.
