(Digital Presentation) Charge Transfer Kinetics of the Ti(IV)/Ti(III) Redox Couple in the Cesium Chloride-Cesium Fluoride Melt with Addition of Alkaline Earth Metal Cations

Abstract

The electrochemical behavior of the Ti(IV)/Ti(III) redox couple in the CsCl-CsF(10 wt.%)-K2TiF6 melt was studied. The standard rate constants of charge transfer for the Ti(IV)/Ti(III) redox couple in CsCl-CsF(10 wt.%)-K2TiF6-based melts with additions of alkaline earth metal cations (Mg2+, Ca2+, Sr2+ and Ba2+) were determined by cyclic voltammetry method. The activation energies of charge transfer process were calculated. The linear dependence of charge transfer rate constants on the ionic potential of alkaline earth metal cations was found.
