Abstract:
1. A method for forming a lamellar mesoporous silica composition which comprises: (a) reacting in a reaction mixture a lower alkyl tetraorthosilicate with an amine surfactant, wherein the surfactant is of the formula: wherein y is 1 to 4, R is an alkyl moiety containing 10 to 20 carbon atoms and R 1 is selected from the group consisting of hydrogen, methyl, ethyl and (CH 2 ) m NH 2 wherein m is 1, 2, 3 or 4, to form the lamellar mesoporous silica composition; and (b) separating the composition from the reaction mixture; (c) removing the surfactant from (b) to provide the lamellar mesoporous silica composition, wherein cross-linking of SiO
