Abstract

ZSM-5 mesopori dengan variasi waktu aging 24, 12, dan 6 jam telah berhasil disintesis. Fase mesopori dibuat dengan menggunakan templat cetiltrimetilamonium bromida (CTABr). Sintesis ini dilakukan dengan menggunakan metode hidrotermal dengan suhu aging dan kristalisasi 60°C dan 150°C. Pimcak difraksi karakteristik ZSM-5 muncul pada 2θ = 7–9° dan 2θ = 23,02°. Kristalinitas akan meningkat seiring dengan penambahan waktu aging. Hasil analisa adsorpsi-desorpsi nitrogen menunjukkan bahwa semua sampel memiliki ukuran pori sekitar 3,8 nm. Selain itu pengurangan waktu aging akan menyebabkan penurunan porositas. ZSM-5 yang disintesis dengan waktu aging 6 jam memiliki porositas yang paling besar. Waktu aging juga berpengaruh pada ukuran partikel, semakin lama waktu aging menyebabkan ukuran partikel yang semakin kecil.

Mesoporous ZSM-5 with variation of aging time i.e. 24, 12, and 6 h have been successfully synthesized. Mesoporous phase of ZSM-5 was synthesized using template cetyltrimethylammonium bromide (CTABr). Synthesis was carried out using hydrothermal method with aging and crystallization temperature at 60°C and 150°C, respectively. Characteristic diffraction peaks of ZSM-5 appeared at 2θ = 7–9° and 2θ = 23.02°. Crystallinity increased as aging time increased. The result of nitrogen sorption analysis showed that all samples have pore size about 3,8 nm. The porosity of ZSM-5 decreased with shorter of aging time. Synthesized ZSM-5 with 6 h aging time has the highest porosity. Aging time had also affects the particle size, whereas the particle size will become smaller along with the longer of aging time.
