Abstract

Material tembaga-benzentrikarboksilat (Cu-BTC) dan kobalt-tembaga-benzentrikarboksilat (Co-Cu-BTC) telah berhasil disintesis dengan metode solvotermal pada suhu 100 °C selama 10 jam. Sintesis ini dilakukan dengan penambahan variasi mol Co(II) sebesar 2,5%; 5% dan 10% yang diikuti dengan pengurangan mol Cu(II). Cu-BTC dan Co-Cu-BTC hasil sintesis selanjutnya dikarakterisasi menggunakan XRD, FTIR, SEMEDX, TGA dan BET. Difraktogram muncul pada sudut khas HKUST-1 yaitu 2θ = 11,6° ; 9,5° dan 2θ = 13,4°. Penambahan Co2+ mempengaruhi pergeseran puncak difraktogram dan intensitas puncak. Analisa FTIR menunjukkan bahwa penambahan Co2+ tidak mempengaruhi gugus fungsi yang ada pada material Cu-BTC. Penambahan Co2+ mempengaruhi keseragaman dari morfologi HKUST-1 ditunjukkan dengan analisa SEM-EDX. Analisa TGA menunjukkan Co-Cu-BTC memiliki stabilitas termal sebesar 354 °C. Luas permukaan yang dimiliki oleh Cu-BTC dan Co-Cu-BTC 5% masing-masing sebesar 1149 m2/g dan 1033 m2/g. Pada uji reaksi esterifikasi menunjukkan bahwa Co-Cu-BTC 2,5% mampu meningkatkan konversi FFA yaitu sebesar 44,17%. ============================================================ Copper-benzenetricarboxylic (Cu-BTC) and Cobaltcopper- benzenetricarboxylic (Co-Cu-BTC) have been successfully synthesized. The synthesis is carried out with the addition of variations mole Co (II) of 2.5%; 5% and 10%, followed by reduction of the mole Cu (II). This material is synthesized using solvothermal methods on 100 °C for 10 hours. Cu-BTC and Co-Cu-BTC subsequently were characterized using XRD, FTIR, SEM-EDX TGA and adsorption-desorption N2. Diffractogram apper on 2θ = 11,6°; 9,5° and 2θ = 13,4°. The addition of Co2+ affect diffractogram peak shift and peak intensity. FTIR analysis showed that the addition of Co2+ doesn’t affect the functional groups in Cu-BTC. The addition of Co2+ affect the uniformity of the morphology of HKUST-1 was shown by SEM-EDX analysis. TGA analysis showed that Co-Cu-BTC has thermal stability at 354 °C. In esterification reaction showed that Co-Cu-BTC 2,5% capable to convert FFA in amount of 44,17%
