Abstract
Hierarchical zeolite possessing MFI framework type was hydrothermally prepared usingC22H45− N+(CH3)2− C6H12− N+(CH3)2− C6H13as a structure-directing agent in a seed-assisted synthesismethod. The nanosponge-like morphology was composed of a three-dimensional disordered network ofMFI layers with 2.5 nm thickness supporting each other. Catalytic performance of the MFI nanospongewas investigated in glycerol etherification with tert-butyl alcohol in liquid phase and compared toconventional microporous MFI zeolite and MFI unilamelar nanosheet. The hierarchical zeolites weremuch more active, which can be attributed to the acid sites located on the external surfaces accessiblefor the reaction of bulky reactants. © 2016 Elsevier B.V.
