Abstract

HKUST-1 dan komposit ZIF-8/HKUST-1 dengan penambahan massa ZIF-8 terhadap HKUST-1 sebesar 5% berhasil disintesis dengan metode solvotermal dalam campuran pelarut aqua DM:etanol:DMF dengan perbandingan 1:1:1 (v/v) pada suhu 100 ⁰C selama 10 jam. Material komposit GO/ZIF-8/HKUST-1 dengan penambahan variasi massa Grafena Oksida (GO) terhadap HKUST-1 sebesar 5, 10, dan 20% berhasil disintesis dengan metode impregnasi, yang berturut-turut dinotasikan sebagai GO(5)/ZIF-8/HKUST-1, GO(10)/ZIF-8/HKUST-1, dan GO(20)/ZIF-8/HKUST-1. Hasil uji X-Ray Diffraction (XRD) menunjukkan pola difraktogram dengan puncak karakteristik yang sesuai dengan pola HKUST-1 standar. Spektroskopi Fourier Transform Infrared (FTIR) material hasil sintesis memiliki pita serapan pada bilangan gelombang yang sama dengan HKUST-1 yang telah dilaporkan. Uji Scanning electron microscopy (SEM) menunjukkan morfologi HKUST-1 berupa kristal oktahedron yang sesuai dengan yang dilaporkan. Hasil uji adsorpsi pada 50 mg/L congo red (CR) didapatkan bahwa material komposit GO(10)/ZIF-8/HKUST-1 menunjukkan waktu adsorpsi optimum pada 50 menit dengan kapasitas adsorpsi sebesar 83,9211 mg/g. Pada hasil uji fotokatalitik terhadap pengurangan kadar CR menunjukan bahwa material komposit GO(10)/ZIF-8/HKUST-1 memiliki presentase removal tertinggi, yaitu sebesar 88% dengan waktu kontak selama 100 menit dan dosis fotokatalis 10 mg dalam 20 mL larutan CR.

HKUST-1 and ZIF-8/HKUST-1 composite with the addition of 5% mass of ZIF-8 to HKUST-1 were successfully synthesized by the solvothermal method in a mixture of aqua solvent DM:ethanol:DMF with a ratio of 1:1:1 (v/v ) at 100 ⁰C for 10 hours. The GO/ZIF-8/HKUST-1 composite material with the addition of graphene oxide (GO) mass variation to HKUST-1 of 5, 10, and 20% was successfully synthesized by the impregnation method, which were denoted as GO(5)/ZIF, respectively. -8/HKUST-1, GO(10)/ZIF-8/HKUST-1, and GO(20)/ZIF-8/HKUST-1. The results of the X-Ray Diffraction (XRD) test showed a diffractogram pattern with characteristic peaks that matched the standard HKUST-1 pattern. Fourier Transform Infrared (FTIR) spectroscopy of the synthesized material has an absorption band at the same wavenumber as HKUST-1 which has been reported. Scanning electron microscopy (SEM) test showed the morphology of HKUST-1 in the form of octahedral crystals which was in accordance with what was reported. The results of the adsorption test at 50 mg/L congo red (CR) showed that the GO(10)/ZIF-8/HKUST-1 composite material showed the optimum adsorption time at 50 minutes with an adsorption capacity of 83.9211 mg/g. The results of the photocatalytic test for removal CR showed that the GO(10)/ZIF-8/HKUST-1 composite material had the highest removal percentage, which was 88% with a contact time of 100 minutes and a photocatalyst dose of 10 mg in 20 mL of CR solution.
