Abstract

UiO-66 dan Al-MCM-41/UiO-66 dengan variasi massa Al-MCM-41 terhadap UiO-66 sebesar 10,78; 21,56; 43,12 dan 86,24% telah berhasil disintesis dengan metode solvotermal dalam pelarut DMF pada suhu 120 °C selama 24 jam. Difraktogram UiO-66 dan Al-MCM-41/UiO-66 menunjukkan puncak karakteristik pada 2θ sekitar 7,4 dan 8,5°, yang sama dengan difraktogram UiO-66 standar. Spektra FTIR material hasil sintesis menunjukkan puncak serapan spesifik dari UiO-66 yaitu pada bilangan gelombang 1649-1656; 1506-1582; 1400; dan 660-665 cm-1. Hasil adsorpsi desorpsi N2 menunjukkan bahwa luas permukaan spesifik Al-MCM-41/UiO-66 (2) (413,106 m2/g) lebih rendah dibandingkan UiO-66 (466,997 m2/g). Hasil katalisis antara asam oleat dengan metanol menunjukkan bahwa yield metil oleat dengan katalis Al-MCM-41/UiO-66 (2) (28,83%) lebih besar dibandingkan dengan katalis UiO-66 (8,82%). ============================================================================================= UiO-66 dan Al-MCM-41/UiO-66 with mass variation of Al-MCM-41 to UiO-66 at 10,78 ; 21,56 ; 43,12 dan 86,24% had been synthesized by solvothermal method using DMF as solvent at 120 °C for 24 hours. XRD pattern of UiO-66 and Al-MCM-41/UiO-66 had similar peaks at 2θ = 7,4 and 8,5°. FTIR spectra of materials showed characteristics peaks of UiO-66 at wavenumbers 1649-1656; 1506-1582; 1400; and 663-665 cm-1. The result of N2 adsorption desorption showed that specific surface area Al-MCM-41/UiO-66 (2) (413,106 m2/g) was lower than UiO-66 (466,997 m2/g). Esterification of oleic acid with methanol showed that yield methyl oleate by using Al-MCM-41/UiO-66 (2) (28,83%) was higher than using UiO-66 (8,82%).
