Synthesis and Characterization of UiO-66 Metal Organic Framework Nanostructure

The purpose of the present work is to synthesize and characterize of the nanostructure of the metal organic framework of UiO-66. Synthesis was performed using zirconium tetrachloride, terephthalic acid, N, N-dimethylformamide and chloroform. The synthesized UiO-66 was characterized by XRD, FT-IR, FESEM and BET analysis. In the XRD curve, characteristic peaks were observed at 2θ angles of 7.4°, 8.5° and 25.8°, which confirm the successful synthesis of UiO-66 crystalline nanoparticles. The FT-IR analysis showed the formation of functional groups of OH at 3428 cm-1, O-C-O asymmetric stretch at 1566 cm-1, O-C-O symmetric stretch at 1399 cm-1 and Zr-O bond stretching vibration of the framework at 1082 cm-1 in UiO-66 structure. The results of FESEM analysis showed the formation of single cubic crystals of UiO-66 with octagonal morphology and nanoparticles were observed in the range of 30 to 60 nm. Nitrogen adsorption-desorption curve of UiO-66 was from type I and the specific surface area of ​​BET, total pore volume and average pore diameter were 1130.9 m2/g, 1.1429 cm3/g and 4.425 nm, respectively, which confirm the large surface area and high pore volume of UiO-66.
