Electron transfer at nickel electrode

There is considerable contemporary interest in the electron transfer reaction. at active (transition) metal electrodes. this work reports the electrochemical behavior of potassium ferrocyanide at nickel electrode in aqueous potassium nitrate solution. Potassium ferrocyanide is frequently employed to probe one-electron transfer reactions at solid, electrodes. It was found that the voltammetric oxidation of ferrocyanide at nickel is a simple electron transfer reaction. Normal pulse voltammetry revealed similar behavior. (author)
