Preparation and characterization of ZSM-5 zeolites with various templates

ZSM-5 zeolite with similar Si/Al ratio were synthesized successfully using various templates ( nbutylamine (BTA), Tetrapropyl ammonium hydroxide (TPAOH), Tetrapropyl ammonium bromide (TPABr), Ethylenediamine (EDA), isopropylamine (IPA) and no template (NT)) under hydrothermal conditions. The samples were characterized by XRD, SEM, FT-IR, in order to understand the template effect and the difference of ZSM-5 samples. The syntheses of ZSM-5 with organic templates were relatively easier than without template. SEM result revealed that ZSM-5 with different templates had different morphology and particle size.
