Abstract
A mesoporous silicate is prepared by a method that includes combining a silicate precursor, a bifunctional catalyst, and a structure-directing surfactant in an aqueous medium having a pH of about 4 to about 10. A mesoporous silicate forms as an aqueous suspension and can then be isolated. The mesoporous silicate can be formed under mild conditions of temperature and pH, and it exhibits a surprisingly high degree of network condensation.
