Sulphite Electrooxidation in Alkaline Media on Skeletal Nickel Based 6 Layers Platinum Nanoparticles Electrode

Abstract:

In this paper, anodic oxidation of sulphite ions on skeletal nickel based platinum nanoparticles electrode (6 layers) in aqueous alkaline solution was investigated in order to find the relationship between kinetic parameters and sulphite concentration. The purpose of this research is both to understand the oxidation mechanism and determine optimal parameters for oxidation process. Electrochemical behavior of sulphite ions has been studied by cyclic voltammetry and linear polarization. Tafel method was used in order to determine kinetic parameters and electrochemical impedance spectroscopy studies were performed to confirm the oxidation mechanism. For a complete characterization of sulphite electrooxidation process chrono-electrochemical methods (chronoamperometry, chronopotentiometry, chronocoulometry) were used.
