Study of alkaline earth metals cations influence on the electrochemical behaviour of the Ti (IV) / Ti (III) redox couple in the CsCl — CsF melt

The influence of the alkaline earth metal cations (Mg2+, Ca2+, Sr2+ и Ва2+) on the charge transfer kinetics of the Ti (IV) / Ti (III) redox couple in melts of alkali metal halides was studied by cyclic voltammetry method. Standard rate constants of charge transfer have been determined by the Nicholson method. The activation energies of the charge transfer process in the CsCl — CsF (10 wt. %) — K2TiF6 melt with the addition of alkaline earth metal cations were calculated.
