Nanozeolite Na-Y was synthesized hydrothermally and without aging process. Nanocrystalline zeolite Y was extensively characterized by powder X-ray diffraction . Spectroscopic characterization of the this zeolite by FT-IR provided detailed structural information . This study was indicated that colloidal zeolite Y with an average particle size of 45 nm and with high crystallinity was obtained .
