Carbide-derived carbon (CDC) has been examined due to its useful conformal character. However, its variety of chemical composition is limited because functionalized atoms in its carbonaceous structure, especially with nitrogen, are unstable during high-temperature processing. In this paper, we report the enhanced nitrogen stability and an increase in surface area by boron addition. We also synthesized a hollow granule structure of nitrogen/boron co-doped porous carbon (CNB) in high yield by using a nitrogen-rich precursor without any additive template. High CO2 capture (3.7 mmol/g) was measured at ambient temperature and 1bar with an excellent CO2/N2 selectivity.
