A simple and versatile synthetic route, whereby primary amine surfactants are the template in the assembly of aluminosilicate inorganic species, is used to prepare aluminosilicate mesoporous molecular sieves in which Broensted acidity is generated by simply calcining the as-synthesized material. Al incorporation is accompanied by charge-balancing protonated amine molecules. Si and Al are incorporated into the mesoporous framework to yield materials with textural properties similar to those of MCM-41 but with substantially higher Broensted acidity.
