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, N2 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 m2/g. The FESEM images showed coffin-shaped and broom-like crystals of ZSM-5.
