The objective of this work is to give a comparative characterization of the three-dimensional (3D) MSU-2 and unidimensional (1D) MCM-41-like aluminosilicates, in particular with respect to acidity and catalytic properties in 1,3,5-triisopropylbenzene cracking. Mesoporous AlMSU-2 with wormhole but uniform pores and large surface area, previously obtainable only from silicon alkoxides, has been successfully...
Nanometer-sized (below 100°nm) bimodal mesoporous aluminosilicate molecular sieves (NBMAS) are obtained by using sol–gel method and cetyltrimethylammonium bromide (CTAB) as the structure-directing agent. Ordering-packed framework mesopore is created within the colloidal particles by the templating function of surfactant CTAB and disordered textual pore is formed by the aggregation of colloidal particles...
