摘要：

Mesoporous carbonaceous materials (Starbons (R)) derived from low-value/waste bio-resources separate CO2 from CO2/N-2 mixtures. Compared to Norit activated charcoal (AC), Starbons (R) 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 (R) also showed three-four times higher selectivity for CO2 adsorption rather than N-2 adsorption compared to AC.
