Mordenite is generally referred to be a one-dimensional micropore zeolite. The major drawback of this pore structure is severe diffusion limitations, especially for the reactions involving bulky molecules. Herein, hierarchical mordenites were successfully prepared through a soft-templating method using a diquaternary ammonium surfactant [C18H37N+(CH3)2C6H12N+(CH3)2C6H13(Br-)2, C18-6-6Br2 for short] as mesoporogen. The obtained samples were characterized by XRD, FT-IR, SEM, TEM, TG-DTG, N2 physical adsorptio...
