CO2 sorption on surface-modified carbonaceous support: Probing the influence of the carbon black microporosity and surface polarity

- CO2-sorbent materials preparation by surface modification of CB.
- CB functionalization (amino-groups), CB coating (Fe3O4), CB impregnation (ionic liquid).
- Sorbents bearing basic functionalities exhibit the higher CO2 sorption capacity.
- Microporous supporting material limits the CO2 accessibility toward the adsorbing material.
