CARBON DIOXIDE CAPTURING AGENT, METAL-ORGANIC FRAMEWORK, AND COMPOUND

Title:

CARBON DIOXIDE CAPTURING AGENT, METAL-ORGANIC FRAMEWORK, AND COMPOUND

Document Type and Number:

WIPO Patent Application WO/2023/033035

Kind Code:

A1

Abstract:

[Problem] To provide a novel carbon dioxide capturing agent and the like whereby it is possible to capture carbon dioxide. [Solution] A carbon dioxide capturing agent containing a metal-organic framework, wherein the metal-organic framework is capable of capturing carbon dioxide and of releasing carbon dioxide, an isolated space is formed in the interior of the metal-organic framework by the three-dimensional structure of the metal-organic framework, the isolated space is a space capable of capturing carbon dioxide and does not normally include channels through which carbon dioxide can pass, and although the three-dimensional structure of the metal-organic framework changes in the process of carbon dioxide being captured within the isolated space and in the process of carbon dioxide being released from the isolated space, the three-dimensional structure of the metal-organic framework when carbon dioxide is captured in the isolated space and the three-dimensional structure of the metal-organic framework when carbon dioxide is not captured in the isolated space are the same.
