Controlling Yield of NaY Zeolite Synthesis by Hydrothermal Method

NaY Zeolite was hydrothermally synthesized by seeding crystals into gel mixture without the presence of organic templates, structure-directing agent, and additives. An alternative condition for the production of NaY Zeolite was developed by modified the pH in gel formation. The effect of pH and crystallization time in yield NaY Zeolite crystal was investigated with reducing the pH value. The as-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray Fluorescence (XRF), Brunauer-Emmett-Teller (BET), and Fourier-Transformation Infrared (FT-IR) spectroscopy and Raman spectroscopy. As results, we verify that NaY Zeolite obtained from hydrothermal condition, present a good degree of crystallinity and then can be suitable for using in adsorption and catalysis experiments.
