Abstract

Material UiO-66 dan ZnO/UiO-66 telah berhasil disintesis dengan penambahan ZnO pada variasi massa sebesar 5% terhadap massa total UiO-66, dengan metode solvotermal pada suhu 120°C selama 24 jam. Selanjutnya, komposit GO@ZnO/UiO-66 berhasil disintesis dengan metode impregnasi pada variasi massa penambahan Grafena Oksida (GO) sebesar 5, 10, dan 20% terhadap massa total UiO-66, dan material yang dihasilkan dinotasikan sebagai GO(5)@ZnO/UiO-66, GO(10)@ZnO/UiO-66, serta GO(20)@ZnO/UiO-66. Hasil sintesis dikarakterisasi dengan instrument XRD, FTIR, dan SEM-EDX. Pola difraktogram XRD menunjukkan puncak karakteristik pada 2θ yang sesuai dengan difraktogram UiO-66 standar. Spektra FTIR menunjukkan pita serapan pada bilangan gelombang sesuai dengan UiO-66 standar. Morfologi permukaan material hasil sintesis berupa butiran kristal yang bentuknya mirip dengan morfologi UiO-66. Penambahan ZnO dan GO pada komposit GO@ZnO/UiO-66 memberikan pengaruh terhadap morfologi kristal menjadi teraglomerasi dan semakin tidak beraturan sesuai dengan hasil analisis SEM. Hasil uji adsorpsi terhadap methyl orange dengan konsentrasi 100 mg/L menunjukkan bahwa material GO(10)@ZnO/UiO-66 memiliki kapasitas adsorpsi sebesar 117,36 mg/g pada waktu adsorpsi optimum 50 menit. Hasil uji fotokatalitik terhadap pengurangan kadar methyl orange dengan konsentrasi 100 mg/L menunjukan bahwa material GO(10)@ZnO/UiO-66 memiliki persen penghapusan tertinggi, yaitu sebesar 66,87% dengan waktu kontak selama 120 menit dan dosis fotokatalis 10 mg dalam 20 mL larutan methyl orange.

UiO-66 and ZnO/UiO-66 materials has been successfully synthesized by adding ZnO at a mass variation of 5% to the total mass of UiO-66, using the solvothermal method at 120°C for 24 hours. Futhermore, the GO@ZnO/UiO-66 composite material was successfully synthesized by the impregnation method at a mass variation of 5, 10, and 20% addition of Graphene Oxide (GO) to the total mass of UiO-66, and the resulting material is were denoted as GO(5)@ZnO/UiO-66, GO(10)@ZnO/UiO-66, and GO(20)@ZnO/UiO-66. The results of the synthesis were characterized by XRD, FTIR, and SEM-EDX instruments. The XRD diffractogram pattern shows characteristic peaks at 2θ which corresponds to the standard UiO-66 diffractogram. The FTIR spectra showed the absorption band at the wavenumber according to the standard UiO-66. The surface morphology of the synthesized material was in the form of crystalline grains that was similar in shape to the morphology of UiO-66. The addition of ZnO and GO to the GO@ZnO/UiO-66 composite gave an effect on the crystal morphology to become agglomerated and more irregular according to the results of SEM analysis. The results of the adsorption test on methyl orange with a concentration of 100 mg/L showed that the GO(10)@ZnO/UiO-66 material had an adsorption capacity of 117,36 mg/g at the optimum adsorption time of 50 minutes. The results of the photocatalytic test for removal of methyl orange at a concentration of 100 mg/L showed that the GO(10)@ZnO/UiO-66 material had the highest removal percentage, which was 66.87% at a contact time of 120 minutes and a photocatalyst dose of 10 mg in 20 mL of methyl orange solution.
