Abstract

There is provided a crystalline oxide material with a characteristic X-ray diffraction pattern. This material may be a layered material, which is swollen or pillared. Upon calcination of the swollen material, the layers collapse and condense upon one another in a somewhat disordered fashion to form a non-swellable material. However, the swollen layered material may be intercalated with polymeric oxide pillars to maintain layer separation, even after calcination.
