Roles of local deviations and fluctuations of the helmholtz-layer potential in transitions from stationary to oscillatory currents in an "H (sub 2) O (sub 2)- acid-Pt" electrochemical system
Article Abstract:
The mechanism of transitions from stationary to oscillatory currents is studied for hydrogen oxide reduction at platinum electrodes in acidic solutions. The transitions were observed in current versus time curves after the electrode potential is stepped from the rest potential to a potential where an oscillation appeared.

Catalytic effect of adsorbed iodine atoms on hydrogen peroxide reduction at single-crystal Pt electrodes, causing enhanced current oscillations
Article Abstract:
The oscillation E is enhanced much by the presence of adsorbed iodine atoms. The adsorbed iodine atoms have catalytic effect on the dissociative adsorption of H2O2, which leads to the enhancement of oscillation E.
