A range of nanoporous aluminosilicates varying in their aluminium content were synthesised using all evaporation-induced self-assembly (EISA) approach under acidic conditions. The nanoporous materials produced display narrow pore size distributions and the expected large BET sui face areas The activity and selectivity of these materials to function as Lewis acid catalysts for the addition of alcohols to styrene oxide and cyclohexene oxide were assessed and found to be optimum using high aluminium containing materials.
