Title:
SUPER-MICROPOROUS ZIRCONIUM-BASED METAL-ORGANIC FRAMEWORK MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/143112
Kind Code:
A1
Abstract:
Provided are a super-microporous zirconium-based metal-organic framework material, a preparation method therefor, and the use thereof. The method involves: (1) dissolving zirconium chloride and alkaline N-pyrazine into DMF, and performing ultrasonic dissolution to obtain a mixed solution; (2) subjecting the mixed solution to a microwave reaction; (3) adding DMF, acetic acid and terephthalic acid to same, and stirring same to obtain a mixed solution; (4) transferring the mixed solution to a reaction kettle for a reaction; and (5) subjecting same to washing, centrifugation and drying treatments. The zirconium-based MOF material constructed using a microwave-assisted strategy has a higher specific surface area and a smaller pore size distribution, while acidic sites of MOF metal sites are weakened. This synergistic effect significantly improves the adsorption capacity thereof for CO2.
