Abstract

The organometallic polymer UiO-66 was synthesized and characterized. Samples of the resulting material after drying at two different temperatures (100 and 300°C) were studied using various analytical methods. IR absorption spectra of the synthesized samples were recorded in the range from 500 to 3500 cm–1, and the main absorption bands of the synthesized polymer UiO-66 were confirmed. The crystal lattice parameters of the samples for two temperatures were determined to be 20.10(5) Å at 100°C and 20.52(4) Å at 300°C, with the characteristic sizes of coherent scattering regions (CSR) of X-ray radiation being ~44 Å at 100°C and ~37 Å at 300°C. The specific surface area was calculated using the BET method, and the specific surface area of the sample after drying at 100°C was estimated to be S ~ 363 m2/g, while the characteristic size of microparticles was ~18 μm. As a result of the synthesis, a single-phase material with a type of X-ray diffraction pattern characteristic of UiO-66 was obtained. It has been shown that drying at 300°C structures the resulting material in the [111] direction, while other directions become amorphized.
