Defined Intercalation Stages from Cathodic Reduction of MoS2 in Organic Electrolytes

Abstract

Cathodic reduction of MoS₂ in DMSO electrolytes containing alkali cations A⁺ results in the formation of defined ternary phases A+^0.125 (DMSO)_y[MoS₂]^0.125- with highly mobile solvated interlayer cations. Reduction of MoS₂ in DME electrolytes yields similar products. Basal spacings are dependant on solvent type and on ionic radius of A⁺. Further reduction of these compounds is associated with irreversible processes.
