Abstract
Material HKUST-1 dengan rumus molekul
[Cu3(BTC)2(H2O)3].xH2O berhasil disintesis dengan prekursor
tembaga nitrat dan trimesic acid menggunakan metode
solvotermal dalam pelarut etanol:DMF dan penambahan
modulator asam asetat. Sintesis dilakukan dalam autoklaf
berlapis teflon pada suhu 100 °C selama 10 jam. Campuran
kemudian disaring dan padatan yang diperoleh dicuci dengan
metanol sehingga didapatkan serbuk biru. Serbuk biru
HKUST-1 dikarakterisasi dengan XRD, FTIR, TGA, SEMEDX,
dan absorbsi-desorbsi Nitrogen. Masing-masing padatan
menghasilkan puncak karakteristik HKUST-1 dengan
kristanilitas yang tinggi pada penambahan asam asetat dengan
jumlah tertentu dan menunjukkan ukuran partikel yang
berbeda. Penambahan ekuivalen modulator asam asetat dalam
kondisi optimum menyebabkan ukuran kristal HKUST-1 yang
semakin kecil sedangkan penambahan volume modulator asam
asetat secara berlebih menyebabkan ukuran kristal yang
semakin besar dan tidak beraturan.
=========================================================================================================
Metal Organic Framework typed HKUST-1 with
molecular formula of [Cu3(BTC)2(H2O)3].xH2O have been
synthesized using copper nitrate and trimesic acid as precursor
using solvothermal method in etanol:DMF as a solvent with
addition of acetic acid as a modulator. The synthesis was
performed using teflon-lined autoclave at 100 °C for 10 hours.
The reaction mixture was filtered and the solid was washed
with methanol to obtain the blue powder. The blue powder of
HKUST-1 were characterized with XRD, FTIR, TGA, SEMEDX,
and Nitrogen adsorbtion-desorbtion measurements. Each
of powder are obtained having high crystanillity with a number
of specific acetic acid addition and showing a difference
particle size of crystal. The addition of acetic acid modulator in
optimum condition can lead crystal size smaller while an
excess addition of acetic acid modulator can lead to a bigger
particle size and bulk crystal.
