Abstract
A metal-organic framework (MOF) includes cadmium, magnesium, linking units of 2,5-dihydroxyterephthalic acid complexed with cadmium and magnesium, and units of guanidine in an amount of 1 to 25 percent by weight (wt. %) based on the total weight of the MOF. The units of guanidine are reacted with the linking units of 2,5-dihydroxyterephthalic acid. The MOF is in the shape of spherical particles with a longest dimension of 50 to 250 nanometers (nm).

(canceled)
The method of claim 12, wherein the units of guanidine form amine groups on an outer surface of the MOF.
The method of claim 12, wherein the MOF includes units of guanidine in an amount of 1 to 3 wt. % based on a total weight of the MOF.
The method of claim 12, wherein the MOF includes units of guanidine in an amount of 5 to 7 wt. % based on a total weight of the MOF.
The method of claim 12, wherein the MOF includes units of guanidine in an amount of 8 to 12 wt. % based on a total weight of the MOF.
The method of claim 12, wherein the MOF includes units of guanidine in an amount of 18 to 22 wt. % based on a total weight of the MOF.
(canceled)
A method of CO2 sequestration, including:
- flowing CO2 over a metal-organic framework (MOF) to adsorb the CO2 onto the MOF,
- wherein MOF comprises:
- cadmium;
- magnesium;
- linking units of 2,5-dihydroxyterephthalic acid complexed with cadmium and magnesium;
- and
- units of guanidine in an amount of 1 to 25 percent by weight (wt. %) based on a total weight of the MOF,
- wherein the units of guanidine are reacted with the linking units of 2,5-dihydroxyterephthalic acid,
- wherein the MOF is in the shape of spherical particles with a longest dimension of 50 to 250 nanometers (nm).
