Abstract

Pada penelitian ini telah disintesis katalis Al-MCM-41, Fe-Al-MCM-41, dan Fe-MCM-41 dengan metode hidrotermal. Katalis hasil sintesis dikarakterisasi menggunakan XRD dan FTIR, serta diuji keasamannya dengan menggunakan FTIR-piridin. Hasil karakterisasi dengan menggunakan XRD dan FTIR menunjukkan bahwa katalis Al-MCM-41, Fe-Al-MCM-41 dan Fe-MCM-41 mempunyai struktur yang sama dengan material mesopori MCM-41, yang ditandai dengan munculnya puncak-puncak karakteristik difraktogram pada 2θ sekitar 1,5-2,5°; 3,5-4,5°; 4,5-5,0° dan 6,0-6,5°. Sedangkan pada spektra FTIR muncul 5 puncak spesifik dari MCM-41 yaitu puncak pada bilangan gelombang 466-462; 796-802; 960-968; 1080-1091 dan 1226-1238 cm⁻¹. Hasil uji keasaman dengan FTIR-piridin menunjukkan bahwa nilai keasaman Lewis dan keasaman Bronsted dipengaruhi oleh ion Al dan Fe yang ditambahkan. Peningkatan keasaman katalis sesuai dengan meningkatnya kandungan ion logam.

In this study, Al-MCM-41, Fe-Al-MCM-41, and Fe-MCM-41 catalysts have been synthesized by hydrothermal method. The resulting catalysts were characterized using XRD and FTIR, as well as using FTIR-pyridine for their acidity. The results showed that the diffractogram and the FTIR spectra of the all catalysts confirm similar structure to MCM-41 mesoporous material, characterized by the appearance of characteristic diffraction peaks at 2θ of about 1.5-2.2°; 3.5-4.5°; 4.5-5.0 and 6.0-6.5°. While in the FTIR spectra showed five spesific peaks of MCM-41 at wave numbers of 462-466; 796-802; 960-968; 1080-1091 and 1226-1238 cm⁻¹. Acidity test results with FTIR-pyridine showed that the number of Lewis and Bronsted acid sites were affected by the amount Al and Fe ions added. The increasing acidity of the catalysts was in accordance with the increasing content of the metal ions.
