The cathodic behavior of oxygen-peroxide systems in an alkaline environment pH 14 was determined by the reduction of oxygen to peroxide when the concentration of peroxide is relatively low and by the reduction of peroxide to water when its concentration is relatively large. At low peroxide concentration, Tafel slopes of ca. -2RT3 F were observed. Increase of oxygen pressure translates these Tafel curves without rotation toward increased currents in direct proportion to the pressure. In contrast, peroxide concentration changes do not influence the Tafel slopes in the low concentration range. Tafel slopes at high peroxide concentrations, ca. 200 mv, are, however, translated, without rotation in direct proportion to the concentration of peroxide. Author
