Anomalous Behaviour of Plantinum Electrode in Briggs-Rauscher Oscillating Chemical Reaction

Platinum electronic when given anodic or cathodic treatment show attenuation in potential oscillations in the study of Briggs Rauscher oscillating chemical reaction. Moreover, some electrodes did not even indicate oscillations though the solution was oscillating. Further it was observed that keeping an electrode in Hydrogen peroxide for a number of days rejuvenates its capacity to sense oscillations. Mechanism of such behavior is contemplated.
