Rice husk ash as a renewable source for the production of zeolite NaY and its characterization

Zeolite Y in sodium form (NaY) was synthesized using silica source from rice husk. The as-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence (XRF), BET. As results, we verify that NaY zeolite obtained from the two-step route, presents a good degree of crystallinity and then can be suitable for using in various applications.
