Sustainable Synthesis of Core-Shell Structured ZSM-5@Silicalite-1 Zeolite
文献摘要：
C ore-shell structured ZSM-5@Silicalite-1 zeolite could effectively hinder the deactivation of catalyst surface.Currently,organic structure directing agents(OSDAs) are necessary in the conventional route for the synthesis of this core-shell zeolite under hydrothermal conditions,which is costly and environmental-unfriendly.In this research,a synthesis of the core-shell structured ZSM-5@Silicalite-1 zeolite with a strategy of alcohol filling and zeolite seeding without any organic template or solvent is exhibited.The obtained products are well characterized by X-ray powder diffractometer(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),N2 sorption isotherms,solid magic angle spinning(MAS) NMR,temperature-programmed-desorption of ammonia(NH3-TPD),and X-ray photoelectron spectroscopy(XPS) techniques,in order to confirm the core-shell structure.More importantly,the core-shell structured ZSM-5@Silicalite-1 zeolite exhibits a long lifetime and a high p-xylene selectivity in the alkylation of toluene with methanol,compared with the conventional ZSM-5 catalyst.
