A new microporous carbon material synthesized via thermolysis of a porous aromatic framework embedded with an extra carbon source for low-pressure CO2 uptake.

Pre-introducing an extra carbon source into the porous aromatic framework of PAF-1 followed by thermolysis affords a new microporous carbon material, which demonstrates a CO₂ uptake capacity of 93 cm³ g⁻¹ (equivalent to 4.1 mmol g⁻¹ or 18.2 wt%) at 295 K and 1 bar. [ABSTRACT FROM AUTHOR]
