Abstract

Material Metal Organic Framework tipe HKUST-1 dengan rumus molekul [Cu3(BTC)2(H2O)3].xH2O telah disintesis menggunakan prekursor tembaga nitrat trihidrat dan asam 1,3,5 benzenetrikarboksilat melalui metode solvotermal dalam autoklaf dengan variasi volume pelarut etanol dan dimetilformamida pada suhu 100 C selama 10 jam. Setelah padatan hasil reaksi disaring dan dicuci dengan metanol, diperoleh kristal Cu-BTC berbentuk serbuk berwarna biru cerah. Kristal Cu-BTC dikarakterisasi menggunakan teknik difraksi sinar-X, FT-IR, SEM-EDX dan TGA. Semua kristal yang didapat memiliki derajat kristalinitas yang tinggi dan menunjukkan kristal berbentuk oktahedral. Cu- BTC yang dihasilkan stabil dengan pemanasan hingga suhu ~350 C. Keberadaan DMF menyebabkan ukuran kristal Cu-BTC lebih besar sedangkan pengurangan volume pelarut DMF menyebabkan penurunan massa kristal yang terbentuk dan kurang homogen. =============================================================================================== Metal Organic Framework material typed HKUST-1 with the molecular formula of [Cu3(BTC)2(H2O)3].xH2O has been synthesized using copper nitric acid trihydrate and 1,3,5 benzenetrikarboksilat via solvotermal method in an autoclave with volume variation of ethanol and dimethyl-formamide at temperature of 100 °C for 10 hours. After the solid reaction products filtered and washed with methanol, crystals of Cu-BTCshaped bright blue powder is obtained. Cu-BTC crystals were characterized using X-ray diffraction techniques, FT-IR, SEMEDX and TGA. All crystals are obtained having high crystallinity and show octahedral shaped crystals. Cu-BTC generally stable by heating until 350 °C. The existence of DMF in Cu-BTC lead crystal size larger while DMF solvent volume reduction causes a decrease in the mass of crystals formed and less homogeneous
