Abstract

Katalis TS-1 Mesopori telah disintesis menggunakan metode prekursor nanocluster dengan variasi waktu hidrotermal. Hidrotermal dilakukan pada suhu 80°C selama 0,5; 1; 2 dan 3 hari. Cetiltrimetilamonium bromida digunakan sebagai templat pengarah fasa meso. Padatan hasil sintesis dikarakterisasi menggunakan teknik difraksi sinar-X (XRD), adsorpsi-desorpsi nitrogen, dan spektroskopi Fourier Transform Infrared. Difraktogram XRD menunjukkan bahwa kristalinitas padatan semakin meningkat dengan lama waktu hidrotermal. Analisis adsorpsi-desorpsi nitrogen menunjukkan bahwa sampel mempunyai diameter pori berkisar 3,05-3,80 nm. Uji aktivitas katalitik dilakukan dengan mengaplikasikan sampel pada reaksi hidroksilasi fenol. Kromatrogram hidroksilasi fenol mengindikasikan bahwa sampel katalis TS-1 selektif terhadap pembentukan benzokuinon.

Mesoporous TS-1 catalyst were successfully synthesized using nanocluster method with variation of hydrothermal time. Hydrotermal was carried out at 80°C for 0,5; 1; 2 and 3 days. Cetyltrimethylammonium bromide was used as template for the formation of meso phase. The solid were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, and Fourier Transform Infrared spectroscopy techniques. XRD patterns showed that crystalinity increased as the hydrothermal time increased. Analysis of nitrogen adsorption-desorption showed that samples have pore size between 3,05-3,80 nm. The samples were catalytically tested in the hydroxylation of phenol. Chromatogram of the product indicated that the TS-1 sample were selective in the formation of benzoquinone.
