| Popis: | This work aims to study the electrolytic oxidation of ethanol in alkaline solution by a carbon paste electrode modified with natural phosphate and cobalt (Co-NP/CPE). The electrodes were obtained by depositing the cobalt on carbon-NP substrates by electrodeposition, using potentiostatic and galvanostatic techniques. Morphological characterisation by optical microscopy techniques shows that the Co is well dispersed with the presence of NP particles on the surface of the electrode. The study of the electrode behaviour by voltammetric techniques exhibits a catalytic effect leading to a better result regarding the oxidation of ethanol. Compared to CPE-NP, the cobalt-modified CPE-NP electrode exhibits high electrolytic activity for ethanol oxidation. |
