Abstract:
A lamellar pillared mesoporous metal silicate composition containing a template, wherein the metal is present in place of some of the silicon in the silicate and capable of undergoing a change of oxidation number in an oxidation or reduction reaction, directly prepared by a neutral self-assembly method which comprises reacting a neutral bipolar diamine as the template and neutral inorganic oxide precursors in the presence of a solvent which is a hydrolyzing agent to form a reaction product, aging of the reaction mixture to form the crystalline pillared lamellar metal silicate without removal of the template and the aqueous solution, wherein the molar ratio of neutral template to total inorganic oxide precursor in the composition is between 0.05 and 3 to 1.
