Abstract New method of direct synthesis of Fe-ZSM-5 zeolite using tetrapropyl ammonium bromide (TPABr) as the template is reported in this study. The synthesis was based on one step procedure and did not involve the usual ion-exchange step to effect incorporation of the metal ion. The zeolite sample was characterized by XRD, FT-IR, TGA, SEM with EDX, and BET adsorption techniques. The average diameter of the porous particle of zeolite was about 10 µm and it was a spherical cluster of crystals… Expand
