Abstract

This work aims to study the electro-oxidation of methanol, in an alkaline solution at a nickelmodified carbon paste electrode Ni -CPE, by cyclic voltammetry, impedance measurements and chronoemperometry. X-ray carried out morphological characterizations by and Microscopy Electronic Transmission (MET). Ni has been found to have a better catalytic activity for methanol oxidation; they are simple, less expensive and stable.
