Biowaste-derived 3D honeycomb-like N and S dual-doped hierarchically porous carbons for high-efficient CO₂ capture.

ABSTRACT: Considering the characteristics of abundant narrow micropores of <1 nm, appropriate proportion of mesopores/macropores and suitable surface functionalization for a highly-efficient carbon-based CO₂ adsorbent, we proposed a facile and cost-effective strategy to prepare N and S dual-doped carbons with well-interconnected hierarchical pores. Benefiting from the unique structural features, the resultant optimal material showed a prominent CO₂ uptake of up to 7.76 and 5.19 mmol g^-1 at 273 and 298 K under 1 bar, and importantly, a superb CO₂ uptake of 1.51 mmol g^-1 at 298 K and 0.15 bar was achieved, which was greatly significant for CO₂ capture from the post-combustion flue gases in practical application.
