Resumo: This work aims to investigate the electro oxidation of methanol, in alkaline solution at a copper electrode modified with electrodeposited natural phosphate and nickel (Ni-NP/Cu), by cyclic voltammetry, impedance measurements and square wave voltammetry. Morphological characterizations were performed by SEM and XRD techniques. It was found that Ni dispersed on natural phosphate (NP) shows a catalytic activity towards methanol oxidation better than massive Ni. Ni and NP were fixed on copper electrode by electro deposition using potentiostatic and galvanostatic techniques.
