In this work, nanocrystals zeolite NaX with crystallite sizes ranging from 40-180 nm and NaY with crystallite sizes ranging from 40-170 nm were synthesized. Nano crystalline NaX and NaY zeolites were prepared using sodium aluminosilicate solution and tetramethylammonium hydroxide organic template. The crystal species were characterized by X-ray diffraction (XRD) patterns and morphology of the zeolites subjected to crystallization was characterized by scanning electron microscopy (SEM). From the results, crystallinity of 60% for NaX zeolite phase and 85% for NaY zeolite phase were obtained.
