Microporous carbon materials are envisaged as efficient contenders for mitigating CO2 level and global climate change by virtue of their rich surface chemistry, high specific surface area, tunable pore structures, moderate heat of adsorption, and facile regeneration. Current work presents a solvent-free one-step polymerization and activation approach for designing a series of microporous carbons using economically favorable avenue. Synthesized carbon materials possess a high surface area (1360-4288 m2/g), large pore volumes (1.15-3.04 cm3/g), and hierarchical meso-micro and ultramicroporous structures. These outstanding textural features along with the nitrogen-doping present an excellent gas adsorption performance with the uptake of 6.8 mmol/g (301 mg/g) of CO2 at 273 K and 1 bar. The high adsorption capacities with the facile regeneration make these microporous carbons amongst the most promising adsorbents in clean energy and environmental applications. |
