摘要：The porous carbons have attracted much attention for efficient CO2 capture because of their high specific surface area and large pore volume. However, it remains a challenge to develop porous carbons with high CO2 capture and CO2/N2 selectivity. In this study, the N, S, O co-doped porous carbons (NSOPCs) were prepared through carbonization and activation of a bio-based polybenzoxazine, which was synthesized from renewable furfurylamine, 4,4 '-thiobisphenol, and paraformaldehyde. NSOPCs with different porous structures and heteroatom contents were obtained by adjusting the amount of KOH activator. NSOPCs exhibited great CO2 capture performance with the CO2 uptake of 7.04 mmol g-1 and CO2/N2 selectivity of 27 at 273 K due to their suitable heteroatom doping and pore size distributions.
