Description
Summary:In this study, the effects of several synthesis parameters including aging time, micropore-structure-directing agents, and hydrothermal treatment temperature profile were systematically examined with respect to their impact on the crystallinity of macroscopic zeolite Y spheres formed in the presence of organic anion-exchange resin templates. Spherical resins were utilized as hard templates to shape the zeolite Y particles. Zeolite Y precursors were initially deposited into the pores of the resin template and subsequently crystallized over time through precise control over these synthesis parameters. The resulting zeolite Y spheres were characterized using an array of characterization techniques, including XRD, SEM, TEM, BET, FTIR, and XRF. We identify the optimal conditions for maximizing the crystallinity of the macroscopic zeolite Y particles using resin templates as macroscopic shaping agents. This functional material has the potential to be used as both catalyst and adsorbent in several applications.
