The potentiodynamic behaviour of iridium electrodes in NaHSO<sub>4</sub> - KHSO<sub>4</sub> melts

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 previously observed for platinum [8-11] and are als...

description 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 previously observed for platinum [8-11] and are also common for iridium. The electrochemical behaviour of iridium (1 mm diameter wire, Johnson Matthey, 1.0 cm<sup>2</sup> apparent area) was studied in the NaHSO<sub>4</sub>-KHSO<sub>4</sub> melts at 180-300°C using a conventional three compartment electrolysis cell. Its potential was referred to a Pt/H<sub>2</sub>(1 atm)/KHSO<sub>4</sub>(melt) electrode.
