| Abstract: | Mesoporous carbonaceous materials (Starbons®) derived from low‐value/waste bio‐resources separate CO2 from CO2/N2 mixtures. Compared to Norit activated charcoal (AC), Starbons® have much lower microporosities (8–32 % versus 73 %) yet adsorb up to 65 % more CO2. The presence of interconnected micropores and mesopores is responsible for the enhanced CO2 adsorption. The Starbons® also showed three–four times higher selectivity for CO2 adsorption rather than N2 adsorption compared to AC. |
