This new finding challenges the long-held viewpoint that acid–base interactions between N-containing basic functional groups and acidic CO₂ gas are responsible for the enhanced CO₂ capture capacity of N-doped carbons.enSuperior CO₂ uptake of N-doped activated carbon through hydrogen-bonding interactionSuperior CO(2) uptake of N-doped activated carbon through hydrogen-bonding interactionJournal article002011936210.1039/C2EE21653A0003043549000062-s2.0-8486382050024411Qiao, S.
