FOLETTO, E. L.; KUHNEN, N. C. y JOSE, H. J.. Synthesis of the ZSM-5 zeolite and its structural properties after copper ion-exchange. Cerâmica [online]. 2000, vol.46, n.300, pp. 210-213. ISSN 1678-4553. http://dx.doi.org/10.1590/S0366-69132000000400007.
The ZSM-5 zeolite was synthesized using silica "Aerosil-Degussa ¾ 380 m2/g" as silicon source, in substitution to the sodium trisilicate, which is usually employed in the zeolite synthesis. Subsequently, the copper was incorporated to ZSM-5 by conventional ion-exchange method. X-ray diffraction, scanning electron microscopy, surface area and elemental analysis by atomic absorption have been used to verify ZSM-5 formation and its properties after copper exchange. The results presented ZSM-5 formation in the employed synthesis conditions. The ion-exchanged sample conserved the original ZSM-5 properties.
