Imine-Linked Polymer Based Nitrogen-Doped Porous Activated Carbon for Efficient and Selective CO₂ Capture.

ABSTRACT: The preparation of nitrogen-doped activated carbon (NACs) has received significant attention because of their applications in CO₂ capture and sequestration (CCS) owing to abundant nitrogen atoms on their surface and controllable pore structures by carefully controlled carbonization. We report high-surface-area porous N-doped activated carbons (NAC) by using soft-template-assisted self-assembly followed by thermal decomposition and KOH activation. The activation process was carried out under different temperature conditions (600-800 °C) using polyimine as precursor. The NAC-800 was found to have a high specific surface area (1900 m² g^-1), a desirable micropore size below 1 nm and, more importantly, a large micropore volume (0.98 cm³ g^-1
