Abstract
Official abstract text for this publication.
According to one embodiment, a carbon dioxide adsorbent is provided. The carbon dioxide adsorbent is capable of adsorbing and desorbing carbon dioxide and has a fused heteroaromatic ring structure that includes one or more quinone structures.
First claim
Opening claim text (preview).
What is claimed is: 1 . A carbon dioxide adsorbent which is capable of adsorbing and desorbing carbon dioxide, and comprises a fused heteroaromatic ring structure that includes one or more quinone structures. 2 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent can adsorb carbon dioxide to the quinone structure in reduction state, and the carbon dioxide adsorbent can desorb carbon dioxide from the quinone structure in oxidation state. 3 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent is able to perform oxidation-reduction reaction by electrical response. 4 . The carbon dioxide adsorbent according to claim 3 , wherein the fused heteroaromatic ring structure has one or more selected from the group consisting of a benzene-based heteroaromatic ring structure, a naphthalene-based heteroaromatic ring structure, an anthracene-based heteroaromatic ring structure, and a phenanthrene-based heteroaromatic ring structure. 5 . The carbon dioxide adsorbent according to claim 3 , wherein the fused heteroaromatic ring structure contains one or more selected from the group consisting of nitrogen, oxygen, and sulfur. 6 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent is a porous metal-organic framework. 7 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent is a porous covalent-organic framework. 8 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent is an oligomer or a polymer including molecules containing the fused heteroaromatic ring structure as a unit structure. 9 . The carbon dioxide adsorbent according to claim 1 , wherein the carbon dioxide adsorbent exhibits a higher oxidation-reduction potential than that of oxygen. 10 . A carbon dioxide adsorption-desorption device comprising the carbon dioxide adsorbent according to claim 1 .
