Abstract
Nanocrystalline zeolites with a crystal size smaller than 100 nm are the potential
materials replacing the existing zeolite catalysts due to their larger surface area and less
diffusion limitations. Nanocrystalline zeolite ZSM-5 (MFI), nanocrystalline zeolite Y
(FAU) and nanocrystalline zeolite beta (BEA) were synthesized in the present study
under hydrothermal conditions. The synthesized zeolites were characterized by X-ray
diffraction (XRD), Surface analysis (adsorption-desorption Nitrogen), Scanning
Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and
Temperature-Programmed Desorption (TPD) of ammonia. Nanocrystalline zeolites
show in their XRD results, broadening of the reflections and shorter peak intensity
indicating the presence of small crystals. The zeolite crystal size was in range 50-100
nm as observed from SEM. The nano size of zeolite crystals resulted in large surface
area.
