Cations insertion in molybdenum cluster compounds: electronic structure and electrochemical study using cavity microelectrode
Résumé
Owing to the high lability of cations in the three-dimensional framework of K1+x Mo12S14 (0 ≤ x ≤ 1.6), first-principles calculations and electrochemical methods have been carried out to study the insertion of cations in the empty channels of this compound. The cavity microelectrode that is a suitable electrode for powder material analysis has been used in voltammetric experiments. Results obtained for Li+, Na+, Rb+, K+, Cs+ and NH4 + cations are presented and discussed.
