The electrooxidation of CO on polycrystalline Pt in 1 M HClO4 at 23°C under potentiodynamic conditions exhibits a double current peak. Whether a single or a double current peak is formed depends to a great extent on the amount of CO surface coverage

The potentiodynamic behaviour of iridium electrodes in NaHSO4 - KHSO4 melts
Autor: Zerbino, Jorge Omar, Tacconi, Norma R. de, Calandra, Alfredo J., Arvia, Alejandro Jorge
Noble metal electrodes in aqueous solutions under a triangular potential sweep display current peaks due to the electrosorption and electrodesorption of hydrogen and oxygen species [1-7]. In molten bisulphate electrolytes these characteristics were p
