| Sumario: | [EN] The present work deals with the use of a carbon fiber fabric for electrochemical purposes. To carry out such investigation, suitable working electrodes of C, Pt/C and Pt/PANI/C were manufactured. Two types of electrodes were made from: Yarns pulled out from the woven textile (CYEs) and strips, 1 cm x 2 cm area, cut from the fabric (CSEs). Cyclic voltammetry (CV) was employed to carry out the electrosynthesis processes. Cyclic and linear voltammetry, electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM) were used to study the electrocatalytic properties of carbon modified electrodes (CMEs). X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to know the chemical composition and to describe the morphology of the Pt/PANI/C and Pt/C modified surfaces. Sulphuric and amaranth solutions were chosen for the electrochemical experiments considering the possible applications of CMEs in the field of electrochemical treatment of industrial wastewater polluted with azo dyes. |
