Abstract

Salah satu jenis Metal Organik Framework (MOF) yaitu HKUST-1 dengan rumus molekul [Cu3(BTC)2(H2O)3].3H2O telah berhasil disintesis dengan menggunakan metode solvotermal pada suhu 100 oC selama 10 jam. Prekusor yang digunakan meliputi tembaga nitrat dan asam 1,3,5-benzena trikarboksilat (H3BTC) dalam pelarut etanol:DMF:air serta penambahan polietilen glikol (PEG). Padatan yang diperoleh berupa serbuk berwarna biru dan dikarakterisasi menggunakan XRD, FTIR, SEM-EDX, TGA serta adsopsi-desorpsi nitrogen. Hasil karakterisasi dengan XRD menunjukkan bahwa penambahan PEG sebagai pelarut dapat menghasilkan HKUST-1 dengan kristalinitas yang tinggi. Pada penambahan 6 ml PEG dari 51 ml total volume pelarut diperoleh massa yang paling besar yaitu 2,5753 gram. Penambahan PEG dapat mempengaruhi struktur kristal, semakin banyak PEG yang ditambahkan menyebabkan ukuran kristal menjadi lebih kecil. Stabilitas termal HKUST-1 yang diperoleh sebesar 377 oC. Hasil analisis adsorpsi-desorbsi nitrogen menunjukkan bahwa luas permukaan HKUST-1 murni sebesar 1149,225 m2/g, HKUST-1 dengan PEG 6 ml sebesar 871,399 m2/g dan HKUST-1 dengan PEG 9 ml sebesar 733,197 m2/g. ======================================================== Metal Organic Framework typed HKUST-1 with molecular formula has been synthesized by using Solvothermal at a temperature 100 oC for 10 hours. Siynthesis is performed using copper nitrate and trimesic acid as precursor with ethanol:DMF:aquades and polyethilene glycol (PEG) as a solvent. The blue powder of HKUST-1 is obtained. The HKUST-1 were characterized with XRD, FTIR, SEM-EDX, TGA, and adsorption-desorption nitrogen measurements. The characterization results obtained showed that the addition of PEG as a solvent may produce HKUST-1 with high cristallinity. On the addition of 6 ml PEG from 51 ml total volume of solvent obtained the greatest mass is 2,5753 gram. The stability thermal of HKUST-1 is 377 oC. PEG can influence the crystal structure, the more PEG is added lead crystal size becomes smaller. The result of adsorption-desorbtion nitrogen analysis showed that the surface area of pure HKUST-1 is 1149,225 m2/g, HKUST-1 with PEG 6 ml is 871,399 m2/g and HKUST-1 with PEG 9 ml is 733,197 m2/g.
