ORGANOMETALLIC FRAMEWORK STRUCTURE OF CERIUM (III) BENZENE TRICARBOXYLATE CE-BTC AND METHOD FOR ITS PRODUCTION Russian patent published in 2023 - IPC B01J20/22 C07F5/00 C01F17/10 C01F17/30 B01J20/28 B01J20/30 C07C51/41 C08G83/00 

FIELD: microporous adsorbents.

SUBSTANCE: invention can be used in green energy processes for storing and transporting gases at elevated pressures, separating gas mixtures, and detecting chemical compounds when used in highly selective adsorption sensors. A metalorganic framework structure (MFS) of cerium benzene tricarboxylate Ce-BTC with the chemical formula CeC₁₂H₁₀NO₇ in the dehydrated state is proposed, characterized by thermal stability of the porous framework at temperatures up to 300°C, containing micropores with a specific surface of 750 to 800 m²/g, an average radius of 0.33-0.50 nm, a micropore volume of 0.30-0.35 cm³/g. A method is proposed for obtaining an organometallic framework structure of Ce-BTC.

EFFECT: inventions make it possible to obtain MFS based on rare-earth elements with a precise porous structure, having a narrow pore size distribution, and to improve the sorption characteristics of MFS.
