Abstract

CO₂ interactions with nanoporous S- and N-doped polymer-derived carbon and commercial wood-based carbon were investigated in a broad range of conditions. The results showed that during CO₂ adsorption nitrogen and sulfur species as well as water were released from the carbon surface as a result of chemical reactions of the surface groups with CO₂. Inelastic neutron scattering experiments provided the unprecedented ability to characterize very small amounts of CO₂ and H₂O and revealed for the first time their physical/chemical status in the confined space of nanoporous carbons. The results obtained suggest that the reactivity of the carbon surface should be considered when CO₂ storage media are chosen and when CO₂ is used as a probe to determine the microporosity of carbon materials.
