Applicant has synthesized a family of novel non-pillared metal oxide compositions which have a triple layered perovskite structure and a surface area of at least 30 m2/g. These compositions are described by the empirical formulaAB2M3O10-xwhere A is a monovalent exchangeable cation such as cesium, B is a divalent or trivalent cation such as strontium or lanthanum and M is a +2, +3, +4 or a +5 valent metal such as niobium, titanium, aluminum or copper.
