Synthesis of ZSM ‐5 Zeolite Particles Using Triethanol Amine as Structure‐Directing Agent

The ZSM ‐5 zeolite particles have been prepared using triethanol amine as structure‐directing agent under static hydrothermal condition at 170°C for 7 days. The particles were characterized by X‐ray diffraction ( XRD ), thermogravimetry analysis ( TGA ), differential thermal analysis ( DTA ), Fourier transform infrared ( FTIR ) spectroscopy, N 2 physisorption measurements, and field emission scanning electron microscopy ( FESEM ). The crystalline ZSM ‐5 was found at 170°C/7 days as shown by XRD . The vibration bands at around 549 and 1226 cm −1 in the FTIR spectra indicated the presence of double 5‐ring in ZSM ‐5. The exothermic peak at 395°C in DTA curve indicated the removal of structure‐directing agent. The BET surface area of the particles was 100 m 2 /g. The FESEM images showed coffin‐shaped and broom‐like crystals of ZSM ‐5.
