ELECTROCHEMICAL BEHAVIOUR OF OXYGEN AND HYDROGEN PEROXIDE ON MAGNETITE ELECTRODES

Abstract

The electrochemical behaviour of O and H2O2 on magnetite electrodes was studied by means of both polarization curves and tension build-up and decay curves. In alkaline solutions, the O was reduced at a tension near to that corresponding to the process O2 + 2H2O + 2e = H2O2 + 2OH(-); H2O2 in concentrated solutions (0.01M) was reduced at the same tension. The electrochemical process apparently involves the O arising from the H2O2 decomposition. Anodic and cathodic processes for H2O2 were symmetric. In neutral solutions, the processes concerning O and H2O2 occurred with the intervention of the redox systems of Fe(OH)3, Fe(OH)2 and Fe3O4. The surface modifications of the electrode produced during cathodic or anodic polarization were evidenced by means of electron diffraction.
