Importance of Micropore–Mesopore Interfaces in Carbon Dioxide Capture by Carbon‐Based Materials

Abstract Mesoporous carbonaceous materials (Starbons®) derived from low‐value/waste bio‐resources separate CO 2 from CO 2 /N 2 mixtures. Compared to Norit activated charcoal (AC), Starbons® have much lower microporosities (8–32 % versus 73 %) yet adsorb up to 65 % more CO 2 . The presence of interconnected micropores and mesopores is responsible for the enhanced CO 2 adsorption. The Starbons® also showed three–four times higher selectivity for CO 2 adsorption rather than N 2 adsorption compared to AC.
