In this work, nitrogen-containing porous carbons were produced by replication from an MCM-48 template using sucrose and pyrrole. A pyrrole influenced infiltration of the carbon precursors into the mesoporous silica during the carbonization process using sulfuric acid. This nitrogen-containing porous carbons exhibited the highest CO2 adsorption capacity (2.67 wt% at 60oC with 15% of CO2 in the stream gas), resulting from the higher specific surface area (1326 m2/g), as well as the nitrogen groups doped into the pores of the resultant carbon materials. CO2 cycling regeneration experiments demonstrated that these materials can be used as a potential adsorbent to capture CO2 from the flue gas of thermal power plants with good regeneration capacity. |
