Synthesis and characterization hierarchical HY zeolite using template and non template methods

Abstract

Hierarchical zeolites Y (Y-h) were synthesized using dimethyl dialyl ammonium chloride acrylamide copolymer as a template (Y-hh) and three-stage temperature control strategy without adding any template (Y-hnt) in order to form hierarchical structures. The synthesized zeolites then were characterized by X-Ray Diffraction, Scanning Electron Microscope, and Surface Area Analyzer. Furthermore, Y-h and Y-hnt zeolites were treated with ammonium ion-exchange in order to form HY zeolites. The results showed the XRD pattern of Y-hh and Y-hnt zeolites had specific peaks at position 2θ of 6, 10, and 11°which were characteristics of Y zeolite whereas for Y-hh had slight impurities from NaP. Nitrogen adsorption of Y-hh and Y-hnt zeolites exhibited hysterical loop at P/P°0.7-0.9 indicating the presence of mesoporous in these materials with surface area were 393.496 and 528.82 m2/g, respectively. SEM images of Y-h and Y-hnt zeolites showed cuboid shape which was characteristic of Y zeolite. The HY zeolites were characterized by Fourier Transmitted Infrared and NH3-adsorption to observe its acidity. As comparison, microporous Y zeolite was synthesized. The results indicated that hierarchical zeolites with template and non template methods had higher pore distribution than microporous Y zeolite.
