Abstract:
A process for the preparation of homostructured mixed organic and inorganic cation exchanged layered silicate with galleries between the layers, wherein the galleries between the silicate nanolayers of the said homostructure are co-occupied by protons and onium ions in a molar ratio of protons to onium between about 10 to 90 and 90 to 10, which comprises the steps of:(a) providing an inorganic layered silicate in proton exchanged form; and(b) intercalating an organic onium ion precursor in a solvent into the layered silicate which reacts with the protons in the galleries to form the organic and inorganic cation exchanged layered silicate containing the onium ions and the protons.
