Potentiodynamic E/I profiles of Pt electrodes in molten KHSO4 in the hydrogen electrode region

Autor: Urtizberea, H., Calandra, Alfredo J., Arvia, Alejandro Jorge

The cathodic evolution of hydrogen and its electrooxidation on platinum molten KHSO4 have been studied over a wide range of temperature. The former reaction was mechanistically interpreted in a simple way by assuming that on platinum black the hydrog

The electrochemical reduction of a platinum oxide monolayer anodically formed in NaHSO4−KHSO4 and KHSO4 melts is investigated under equivalent ageing conditions from 185 to 315°C with application of the linear potential sweep technique. The experi

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

When KSCN is added to molten NaNO3 -KNO3 eutectic within the range of 230-316°C, a complex and a relatively violent chemical reaction takes place until a KSCN concentration of ca. 1 mequiv KSCN/100 g eutectic has been added; further addition produce
