Title: NUCLEOPHILIC POROUS CARBON MATERIALS FOR REVERSIBLE CO2 CAPTURE
Abstract:
In some embodiments, the present disclosure pertains to methods of capturing C02 from an environment by associating the environment (e.g., a pressurized environment) with a porous carbon material that comprises a plurality of pores and a plurality of nucleophilic moieties. In some embodiments, the associating results in sorption of C02 to the porous carbon materials. In some embodiments, the sorption of C02 to the porous carbon materials occurs selectively over hydrocarbons in the environment. In some embodiments, the methods of the present disclosure also include a step of releasing captured C02 from porous carbon materials. In some embodiments, the releasing occurs without any heating steps by decreasing environmental pressure. In some embodiments, the methods of the present disclosure also include a step of disposing released C02 and reusing porous carbon materials. Additional embodiments of the present disclosure pertain to porous carbon materials that are used for C02 capture.
