METAL-ORGANIC FRAMEWORK STRUCTURES OF YTTRIUM (III) BENZENE TRICARBOXYLATE Y-BTC FOR HYDROGEN STORAGE AND METHOD FOR ITS PRODUCTION Russian patent published in 2023 - IPC C07F5/00 B01J20/22 B01J20/28 B01J20/30 

FIELD: metal-organic framework structures.

SUBSTANCE: invention relates to a technology for the preparation of microporous adsorbents with a precision porous structure and a narrow pore size distribution, namely, to the metal-organic framework structure (MOF) Y-BTC, chemical formula in the dehydrated state YC₁₂H₁₀NO₇, containing micropores with a specific surface area of 500 up to 850 m²/g, with an average radius of 0.36…0.43 nm, micropore volume of 0.35…0.40 cm³/g. Also proposed is a method for obtaining an organometallic framework structure of Y-BTC.

EFFECT: increase in the adsorption characteristics of MOF for hydrogen, as well as a reduction in the number of types of substances used in the synthesis process, which reduces the cost of production of MOF.
