Electrooxidation of Methanol on Carbon Supported Gold Nanoparticles

摘要：

　　Activated carbon supported gold nanoparticles (Au/C) were prepared by a chemical reduction process using NaBH4 as a reducing agent.The characterization of transmission electron microscope indicated that the Au nanoparticles (AuNPs) in the Au/C catalyst were highly well dispersed on the carbon support.The catalytic activity of the Au/C catalyst for the methanol electrooxidation (MEO) was investigated by the cyclic voltammetry (CV).The results displayed that the Au/C catalyst exhibited a favorable catalytic activity towards the MEO in alkaline solution.Moreover,the competitive adsorption between OH and CH3OH on the surface of the AuNPs in the Au/C catalyst existed in the course of the MEO.Based on this competitive adsorption,the mechanism of the MEO on the Au/C catalyst was further investigated.
