In the present study, a series of alkali-activated carbon materials were prepared by a single-pot polymerization-carbonization-activation method using KOH as a dynamic molecular porogen. The fabricated materials possess a tunable porous network with high specific surface area, large micropore volume, and high population of micropores in sub-nanometer range. At 1 bar, activated carbons adsorbed CO2 efficiently, attributed to their large pore volume (＜ 0.73 nm). Moreover, present work demonstrates an insight mechanism for CO2 adsorption by micropore filling and illustrate the high adsorption potential of micropores with the pore size less than 0.73 nm. Consequently, as-prepared activated carbons are proclaimed as efficient contenders for CO2 adsorption, an effort devoted for a green sustainable environment.
