Abstract
This disclosure relates to a method that includes (1) contacting a solvent with a porous cyclodextrin-based metal organic framework (CD-MOF) adsorbed with CO2 to release CO2, and (2) collecting the released CO2. The CD-MOF includes at least a metal cation and a plurality of cyclodextrin components.
Claims21
A method, comprising:
- contacting a solvent with a porous cyclodextrin metal organic framework (CD-MOF) adsorbed with CO2 to release CO2;
- and
- collecting the released CO2, wherein the CD-MOF includes metal cations and a cyclodextrin, the cyclodextrin having the formula:
- wherein n is an integer ranging from 0 to 10;
- R is an —OH group, and, the metal cations coordinate to a primary face C6 —OH group and glycosidic ring oxygen atom of glycosidic rings of the cyclodextrin, or, to secondary face C2 and C3 —OH groups of alternating glycosidic rings of the cyclodextrin.

A method, comprising:
- disposing a porous cyclodextrin metal organic framework (CD-MOF) in a gas comprising at least about 0.04% by volume of CO2 to form a CD-MOF adsorbed with CO2;
- and
- contacting a solvent with the CD-MOF adsorbed with CO2 to release CO2, wherein the CD-MOF includes metal cations and a cyclodextrin, the cyclodextrin having the formula:
- wherein n is an integer ranging from 0 to 10;
- R is an —OH group, and, the metal cations coordinate to a primary face C6 —OH group and glycosidic ring oxygen atom of glycosidic rings of the cyclodextrin, or, to secondary face C2 and C3 —OH groups of alternating glycosidic rings of the cyclodextrin.
2 more elements
A method, comprising:
- contacting a solvent with a porous cyclodextrin metal organic framework (CD-MOF) adsorbed with CO2 to release CO2, the CD-MOF adsorbed with CO2 comprises at least about 4% by weight of CO2;
- and
- collecting the released CO2, wherein the CD-MOF includes metal cations and a cyclodextrin, the cyclodextrin having the formula:
- wherein n is an integer ranging from 0 to 10;
- R is an —OH group, and, the metal cations coordinate to a primary face C6 —OH group and glycosidic ring oxygen atom of glycosidic rings of the cyclodextrin, or, to secondary face C2 and C3 —OH groups of alternating glycosidic rings of the cyclodextrin.
