Abstract

ZSM-5 mesopori telah berhasil disintesis dari kaolin menggunakan metode kristalisasi dua tahap. ZSM-5 mesopori disintesis dengan rasio molar sebagai berikut : 10Na2O : 100SiO2 : 2Al2O3 : 1800H2O : : 25 CTABr : xTPA, x = 1, 2,5, 5, 10, dan 20. TPAOH berperan sebagai agen pengarah struktur MFI sedangkan CTABr sebagai template pengarah pori meso. Padatan dikarakterisasi dengan XRD, FTIR, dan SEM. Kaolin telah berhasil diubah ke dalam bentuk ZSM-5 berdasarkan hasil karakterisasi menggunakan XRD dan FTIR. Kristalinitas ZSM-5 meningkat seiring dengan meningkatnya jumlah penambahan TPAOH. Hasil karakterisasi sinar-X (XRD) menunjukkan bahwa semakin meningkatnya jumlah penambahan TPAOH maka intensitas puncak karakteristik ZSM-5 juga akan semakin meningkat sehingga diperoleh kristalinitas yang lebih tinggi. Kristalinitas tertinggi telah diamati pada sampel ZSM-5_5TPA sebesar 56,7%. Karakterisasi spektroskopi inframerah (FTIR) menunjukkan bahwa puncak yang terkait dengan kaolinit telah menghilang bersamaan dengan munculnya puncak pada sekitar 1087, 796, dan 459 cm−1 yang merupakan ciri ZSM-5. Hasil analisis menggunakan SEM menunjukkan bahwa material yang telah disintesis memiliki morfologi kubik dengan rentang ukuran partikel 1.15-3.05 µm

Mesoporous ZSM-5 has been successfully synthesized from kaolin using a two-stage crystallization method. Mesoporous ZSM-5 was synthesized with the molar ratio as follows: 10Na2O: 100SiO2: 2Al2O3: 1800H2O : 25CTABr : xTPA, x = 1, 2.5, 5, 10, and 20. TPAOH acts as the MFI structure guiding agent while CTABr acts as the meso pore guiding template. The solid was characterized by XRD, FTIR, and SEM. Kaolin has been successfully converted into ZSM-5 form based on the results of characterization using XRD and FTIR. The crystallinity of ZSM-5 increased with the addition of TPAOH. The results of X-ray characterization (XRD) show that the increasing the number of TPAOH additions, the higher the peak intensity of ZSM-5 will be to obtain a higher crystallinity. Crystallinity was observed in samples ZSM5_5TPA at 56.7%. Infrared spectroscopic characterization (FTIR) showed that the peaks associated with kaolinite had disappeared along with peaks at about 1087, 796, and 459 cm-1 which are characteristic of ZSM-5. Analysis of the results using SEM showed that the material that has been synthesized has cubic morphology with a particle size range of 1.15-3.05 μm.
