Abstract
A composition includes a MXene and a compound sorbed to the MXene. The MXene includes Tx. Tx is a surface termination comprising NH2, R1NH2, or a combination thereof, wherein R1 is a C1-5 alkyl group. The compound sorbed to the MXene includes CO2, H2S, SOy, or a combination of any two or more thereof, wherein y is 1 to 4.
Claims20
A composition comprising:
- a MXene comprising Tx, wherein Tx is a surface termination, the surface termination comprising NH2, R1NH2, or a combination thereof, wherein R1 is a C1-5 alkyl group;
- and
- a compound sorbed to the MXene, the compound comprising CO2, H2S, SOy, or a combination of any two or more thereof, wherein y is 1 to 4.
A method comprising:
- contacting a MXene with a compound while the MXene is at a first temperature of about −78° C. to about 40° C., thereby sorbing the compound to the MXene;
- wherein the MXene comprises Tx, Tx is a surface termination, and the surface termination comprises NH2, R1NH2, or a combination thereof, wherein R1 is a C1-5 alkyl group;
- and
- wherein the compound comprises CO2, H2S, SOy, or a combination of any two or more thereof, wherein y is 1 to 4.
1 more element
A system comprising:
- a plurality of MXene particles comprising Tx, wherein Tx is a surface termination, the surface termination comprising NH2, R1NH2, or a combination thereof, wherein R1 is a C1-5 alkyl group;
- a vessel configured to contain the plurality of MXene particles, the vessel comprising at least one port for influx of a compound;
- and
- a cooling device configured to cool the plurality of MXene particles at a first temperature of about −78° C. to about 40° C.;
- wherein the compound comprises CO2, H2S, SOy, or a combination of any two or more thereof, wherein y is 1 to 4.
