Robust Anionic Framework Based on Sodium–Cerium Terephthalate
Synthesis of anionic metal-organic framework Na[Ce(BDC)<sub>2</sub>(DMF)<sub>2</sub>] based on cerium (III)-sodium terephthalate was performed. The crystal structure, studied by the Rietveld method, consists of anionic [Ce(BDC)<sub>2</sub>]<sup>-</sup> layers, connected by interlayer sodium cations in a 3D network. Variable-temperature PXRD, total X-ray scattering with pair distribution function analysis, and DFT calculations revealed framework structure stability upon DMF elimination and thermal treatment up to 300 °C. Modification with copper cations was performed using wetness impregnation with a Cu(NO<sub>3</sub>)<sub>2</sub> methanol solution to obtain a catalyst for carbon monoxide oxidation. Cu<sup>2+</sup>@Na[Ce(BDC)<sub>2</sub>(DMF)<sub>2</sub>] in situ decomposition leads to the catalytic activity of the resulting CuO/CeO<sub>2</sub> composite during CO gas oxidation by air.
