1. A composition comprising a cationically stabilized vanadate hydrate having the chemical formula MxV2O5·nH2O, wherein M is a cation and having a structure defined by layers of vanadium oxide separated by the cation and water, which provide spacing and stabilization between the layers, wherein the cationically stabilized vanadate hydrate has a greater interplanar spacing when compared to a vanadate hydrate formed by the same method but without the cation, and wherein the interplanar spacing is about 12.9 Å.
