Synthesis and catalytic activity of mesoporous Al-MCM-41/UiO-66 for esterification of oleic acid

UiO-66 and Al-MCM-41/UiO-66 with mass variation of Al-MCM-41 to UiO-66 at 10.78; 21.56; 43.12 and 86.24% had been synthesized by solvothermal method using N,N-dimethylformamide (DMF) as solvent at 120 °C for 24 hours. XRD pattern of UiO-66 and Al-MCM-41/UiO-66 had similar characteristic peaks at 2θ of 7.4 and 8.5°. FTIR spectra of materials showed characteristics peaks of UiO-66 at wavenumbers of 1649-1656; 1506-1582; 1400 and 663-665 cm-1. The result of N2 adsorption desorption showed that specific surface area of Al-MCM-41/UiO-66 (2) (413.106 m2/g) was lower than that of 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%).
