A process for synthesizing a family of non-pillared metal oxide triple layered perovskite has been developed. The perovskite has a surface area of at least 30 m2/g and an empirical formula ofwhere 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. The process involves forming a reaction mixture containing reactive sources of A, B and M at a pH greater than seven and a temperature and time sufficient to form the perovskite. A process for removing contaminants from effluent streams using the above perovskites is also disclosed.
