BACKGROUND

Metal-organic framework (MOF) materials that exhibit permanent porosity have received extensive interest due to their potential applications for gas storage or capture. However, many of the currently used MOFs have limitations, and thus, other types of MOFs having desired characteristics are needed to be used in certain applications.

SUMMARY

Embodiments of the present disclosure provide for metal-organic materials (MOMs), systems using MOMs to separate components in a gas, methods of separating CO2from a gas, and the like.

An embodiment of the method of capturing CO2in a gas, among others, includes: exposing the gas to a metal-organic material (MOM), wherein the gas includes CO2at a concentration in the gas of about 5% or less; and capturing the CO2in the MOM.

An embodiment of the system for capturing CO2in a gas mixture, among others, includes: a first structure including a metal-organic material (MOM), wherein the gas includes CO2at a concentration in the gas of about 5% or less; and a second structure for introducing the gas to the first structure, wherein CO2is removed from the gas after the exposure to the MOM to form a modified gas (CO2free), wherein the second structure flows the modified gas away from the first structure.

An embodiment of the method of separating components in a gas mixture, among others, includes: exposing a gas including a CO2and a second component to a metal-organic material (MOM), wherein the MOM has a greater relative affinity (kinetic and thermodynamic) for the CO2over a second component, wherein the CO2is at a concentration in the gas of about 5% or less; and capturing the first component in the MOM.

An embodiment of the system for separating components in a gas, among others, includes: a first structure including a metal-organic material (MOM), wherein the gas includes CO2and a second component, wherein the MOM has a greater relative affinity for CO2over the second component, wherein the CO2is at a concentration in the gas of about 5% or less; and a second structure for introducing the gas to the first structure, wherein CO2is removed from the gas after the exposure to the MOM to form a modified gas, wherein the second structure flows the modified gas away from the first structure.

An embodiment of the composition, among others, includes: a MOM comprising [Cu(pyr)2(SiF6)]n, wherein n is 1 to 100,000,000, and wherein the MOM has a pore size of about 3.5 Å.
