Abstract

Zirkonium-benzendikarboksilat (Zr-BDC) atau UiO-66, telah disintesis dengan metode solvotermal menggunakan reaktan ZrCl4 dan asam 1,4-benzendikarboksilat dengan pelarut DMF pada suhu 120 ̊ C selama 24 jam. Selain itu UiO-66 juga disintesis dengan pendukung silika mesopori (UiO-66/MCM-41) menggunakan metode yang sama dengan variasi massa silika mesopori 50, 100, dan 200 mg. Padatan yang diperoleh dikarakterisasi dengan XRD, FTIR, SEM-EDX, TGA, dan adsorpsi-desorpsi nitrogen. Semua material yang telah disintesis memiliki puncak difraktogram pada sudut 2θ = 7,4o dan 8,5o dengan intensitas dan pelebaran yang berbeda denganintensitas UiO-66. Material UiO-66 dan UiO-66/MCM-41 memiliki morfologi yang hampir sama, yaitu bulatan kecil-kecil yang bergerombol. Semua material menunjukkan kestabilan termal antara 455-513 ̊ C dengan luas permukaan spesifik UiO-66 (497 m2/g) lebih rendah dibanding UiO-66/MCM-41(50) (614 m2/g) dan UiO- 66/MCM-41(200) 548 m2/g. ===================================================================================================== Zirconium-benzenedicarboxylate or UiO-66, has been synthesized by the method solvothermal using ZrCl 4 reactant and the acid 1,4-benzendikarboksilat with the solvent DMF at 120 ̊ C for 24 hours. In addition UiO-66 is also synthesized by supporters of mesoporous silica (UiO-66/MCM-41) using the same method with mesoporous silica mass variation of 50, 100, and 200 mg. The solids obtained were characterized by XRD, FTIR, SEM-EDX, TGA, and nitrogen adsorption-desorption. All the materials have been synthesized have diffractogram peaks at angles 2θ = 7,4 ̊ and 8,5 ̊with different intensity and widening the intensity UiO-66. Material UiO-66 and UiO- 66/MCM-41 has a similar morphology , namely small dots are clustered. All the material shows thermal stability between 455-513 ̊ C with a specific surface area UiO-66 (497 m2/g) lower than UiO-66/MCM-41(50) (614 m2/g) and UiO- 66/MCM- 41(200) 548 m2/g.
