The new representative of solid acid conductors: the influence of the hydrogen subsystem on physical properties
This project aims to study novel crystals of the family of MmHn(AO4)(m+n)/2 (М = K, Rb, Cs, NH4; AO4 = SO4, SeO4, HPO4, HAsO4), which are actively investigated to elucidate the influence of the hydrogen subsystem on the physicochemical properties of materials, stabilization of phases with high proton conductivity, and with a view to designing new functional materials, including for fuel cells. The current proposal aims to study of new Cs6H(HSO4)3(H2PO4)4 crystals. We expect to obtain precise structural data on an atomic structure of this compound at different temperatures, including information on hydrogen bonded network. Combined with our X-ray data, this information will allow us to establish a relationship between crystal structure and protonic conductivity, that is important both for the characterization of this compound and understanding of the common features in the MmHn(AO4)(m+n)/2 crystal family.
