摘要：
Zeolites (ZSM-5) containing mesopores with a diameter of approximately 20 nm were hydrothermally synthesized using a microwave heating method. Microwave heating promoted the generation of zeolite nanocrystals in the initial stage of the hydrothermal synthesis, and then their self-assembly formed mesopores in the interstices. The formation of mesopores in the zeolites was confirmed by carrying out their surface analysis using scanning electron microscopy, pore size distribution measurements by obtaining N-2 adsorption-desorption isotherms, and dye adsorption experiments.
