摘要

•Hierarchically porous carbons were derived from poly (ionic liquids) with Zn(Ac)2.•The hierarchically porous structure appeared when the mass ratio of Zn(Ac)2/PIL-Ac was greater than 1.•This template could provide more ZnO and gases for pore-forming.•Our carbons owned large specific surface areas and high N contents.•PNC-1 exhibited excellent CO2 adsorption capacity, selectivity, stability and reusability.
