Microporous carbons with high specific surface area (around 3000 m2 /g) were prepared by a single all-in-one route involving the simultaneous polymerization, carbonization and in situ activation of melamine and isophthalaldehyde mixture. It was revealed that carbon materials prepared at 700 oC, in the presence of KOH, exhibits a narrow pore-size distribution than those prepared in the presence of eutectic mixture. Additionally, MIK-700 possesses high micropore volume and as a result present an excellent CO2 adsorption capacity of 9.7 mmol/g at 273 K and 1 bar. Similarly, the high specific area and pore volume contribute a major role in H2 storage at 77 K, exhibiting 4.0 wt. % up take by MIKN-800 (2984 m2/g and 1.98 cm3/g specific surface area and pore volume, respectively). |
