Title: HYDRATED POROUS MATERIALS FOR SELECTIVE CO2 CAPTURE
Abstract:
The present disclosure pertain to porous materials with a plurality of hydrated pores imbibed with water molecules. The present disclosure also pertains to methods of capturing CO2 from an environment by associating the environment with the porous materials. The association can result in the capture of CO2 from the environment by CO2-hydrate formation within the pores of the porous material. Moreover, the capture of CO2 by the porous materials can occur selectively over hydrocarbons in the environment. The methods can also include steps of releasing the captured CO2 from the porous material, disposing the released CO2, and reusing the porous material for additional CO2 capture. The present disclosure also pertains to methods of forming the porous materials by pre-treating a precursor material, activating the pre-treated precursor material to form a porous material, and hydrating the pores of the porous material.
