spectroscopy. The resultant zeolites were mesoporous and showed unique characteristics of a fully crystalline microporous MFI zeolite framework. Mesoporous ZSM-5 synthesized from imidazole based ionic liquids exhibited higher catalytic activity than conventional ZSM-5 in alkylation and cracking reactions. Significantly high catalytic activity of the mesoporous ZSM-5 suggests that large external surface
