AN EXPERIMENTAL APPROACH TO THE REVERSIBLE OXYGEN ELECTRODE,
Abstract
Oxygen electrodes on platinum in 1 M KOH are described which exhibit rest potentials from 0.9 to 1.59 = 0.01 V, vs H2 (1 atm) in the same solution. The electrodes will operate reversibly about these rest potentials with respect to small anodic and cathodic loads. The current/potential (I/E) plots at higher loads are similar in slope and position for electrodes of both low and high rest potential. The effects of impurities, pH, and pressure on these potentials and I/E curves are investigated experimentally. The self-sustaining nature of these potentials is demonstrated by potential/time recovery curves on a 1.45 V electrode. The sorption of oxygen on platinum and the nature of the peroxide electrode are reviewed briefly to clarify the results obtained on the high potential electrodes. (Author)
