Template synthesis and characterization of mesoporous zeolites

Well-crystalline ZSM-5 and zeolite Y having uniform mesopores were synthesized with template route method using carbon aerogels of different mesoporosities. These mesoporous zeolites were characterized with X-ray diffraction, FT-IR spectroscopy, field emission scanning electron microscopy, and N2 adsorption. ZSM-5 having mesopore volume of 0.2–1 cm3 g−1 was obtained. Mesoporous ZSM-5 synthesized by heating at 423 K for 96 h was well-crystalline, which had mesopores of 11 nm in width. Mesoporous zeolite Y was well-crystalline, of which mesopore volume and width were 1.37 cm3 g−1 and 10 nm, respectively.
