“…Except of a possible metal lattice extension as a result of anodic treatment, early suggested by the authors for Pt [6], no explanation was given to explain the observed phenomena at that time. A gradual increase in the anodic and cathodic current in the oxygen region of potential on a metallic Ir electrode during repeated potential cycling was also briefly mentioned by Capon and Parsons in 1972 [7].…”

“…The phenomenon of hysteresis has been associated with the question of charge balance by Laitinen and Enke (1) 35) were slow, then during reduction, the oxide may simply remain in the "PtOH" state. However, this is not a theory which gives a truly irreversible effect, since it would be expected that the PtOH would be reduced given sufficient time, as is indeed indicated by Gilman's charge balance result, and the present work.…”

Studies on the electrochemical formation and reduction of surface oxide at platinum electrodes have been carried out with particular reference to polarization and hysteresis effects in these processes. Comparisons between the results of galvanostatic and potential sweep techniques have been made for three types of surfaces of platinum electrodes prepared by: (a) heating in hydrogen; (6) heating in a flame; and (c) electrolytically forming platinum black surfaces. The dependence of the quantity of reducible oxide formed under prior steady-state potentiostatic conditions has been related to potential and time of anodic polarization. Polarization effects in the reduction of the surface oxide have been evaluated in terms of the potential dependence of the pseudocapacitance maximum for the oxide reduction process, and a mechanism for the reduction is suggested. The relative slowness of the reduction process is important in regard to the question of the role of oxide in the kinetics of electrocatalytic oxidations at platinum anodes. Hysteresis effects in anodic formation and cathodic reduction of the oxide are discussed in terms of a totally irreversible phase transition involving the ad-layer.

“…6 shows a typical voltammetric profile of a Pt electrode exposed to O 2 : 10% for various anodic holding potentials. A narrow reduction peak appears on the cyclic voltammograms, rather similar to that obtained at polycrystalline Pt electrode in aqueous electrolyte [24]. This peak was slightly dependent on the oxygen partial pressure.…”
