"Exfoliation of Inorganic Layered Materials." A starting inorganic material composed of alternating layers of charged material, in the case of protonated titanate the cationic layer is composed of protons while the anionic layer is composed of edge linked TiO6 octahedra. A solvent is chosen such that it has a greater interaction energy with the sheets than they do with each other, and this interaction will replace the bonds holding the sheets together yielding colloidal suspensions of 2D nanosheets.
