A functionalized carbon dioxide sorbent of a functionalized graphene oxide (fGO) substrate having substitution sites substituted with a functional group. The functional groups can be secondary or tertiary amines, a phosphate, a sulfonate or magnetite. The sorbent can have a binder intermixed with the fGO substrate, in the form of pellets, using a hydroxyethyl cellulose binder. A method using the functionalized sorbent provided captures a CO.sub.2 from a flue gas, by passing the flue gas containing moisture and a concentration of CO.sub.2 across the sorbent packed bed of the functionalized sorbent to adsorb selectively a portion of CO.sub.2 in the flue gas onto the fGO of the sorbent. The captured CO.sub.2 can be desorbed from the sorbent by exposure to a fluid at elevated temperature and/or reduced pressure conditions sufficient to desorb the CO.sub.2, and separating and concentrating the desorbed CO.sub.2 from the fluid. The functional moieties can be at least one of a primary and secondary amine, and a secondary function group of tertiary amines, phosphates, sulfonates and/or magnetite.

A carbon-based porous material microscopically exhibiting a three-dimension 1 cross-linked net-like hierarchical pore structure, a specific surface area of 5002,500 m.sup.2/g and a water contact angle greater than 90. The surface of the carbon-based porous material has a through hierarchical pore structure with mesopores nested in macropores and micropores nested in mesopores, the content of mesopores is high, and there are more adsorption activity sites exposed on the surface of the material, so that the diffusion path for organic gas molecules in the adsorption process is shortened. At the same time, the absorption and desorption rates may also be accelerated and the desorption temperature may be lowered. Furthermore, benefits result for solving the desorption and recovery problems of organic gas molecules. Moreover, the defects of ordinary porous carbon materials being easily hygroscopic, having a weakened capacity to adsorb target gas molecules in a humid environment, etc. are further effectively solved.
