“…It is of note that the N content decreased with the raised pyrolysis temperature, which is due to the instability of active N in the carbon framework. As for C 1s ( Figure 3 b,e and Figure S4e–h ), four peaks at around 284.5, 285.2, 286.3, and 288.4 eV are observed indicating the C-C/C=C, C-N/C-O, C=O, and O=C-O, respectively [ 31 ]. Figure 3 c,f and Figure S4i–l compare the N 1s core-level XPS spectra of all samples.…”

Designing of porous carbon system for CO2 uptake has attracted a plenty of interest due to the ever-increasing concerns about climate change and global warming. Herein, a novel N rich porous carbon is prepared by in-situ chemical oxidation polyaniline (PANI) on a surface of multi-walled carbon nanotubes (MWCNTs), and then activated with KOH. The porosity of such carbon materials can be tuned by rational introduction of MWCNTs, adjusting the amount of KOH, and controlling the pyrolysis temperature. The obtained M/P-0.1-600-2 adsorbent possesses a high surface area of 1017 m2 g−1 and a high N content of 3.11 at%. Such M/P-0.1-600-2 adsorbent delivers an enhanced CO2 capture capability of 2.63 mmol g−1 at 298.15 K and five bars, which is 14 times higher than that of pristine MWCNTs (0.18 mmol g−1). In addition, such M/P-0.1-600-2 adsorbent performs with a good stability, with almost no decay in a successive five adsorption-desorption cycles.

“…[13] Among them, the use of N-containing polymers as a precursor has been commonly employed for the preparation of NPCs, mainly due to their industrial feasibility and easy synthesis. [14] Kuo and co-workers fabricated NPCs with a spherical morphology via pyrolysis and activation of covalent benzoxazine framework, which delivers a high surface area of 1469 m 2 g À 1 and 6.8 wt % N content. [14b] Li et al prepared polypyrrole-based NPC with a high N content of 9.6 wt %, which exhibited an excellent CO 2 adsorption capacity.…”

It is highly desirable to design advanced heteroatomic doped porous carbon for wide application. Herein, Ndoped porous carbon (NPC) was developed via the fabrication of high nitrogen cross-linked triazine polymers followed by pyrolysis and activation with controllable porous structure. The as-synthesized NPC at the pyrolysis temperature of 700°C possessed rich nitrogen content (up to 11.51 %) and high specific surface area (1353 m 2 g À 1 ), which led to a high CO 2 adsorption capability at 5.67 mmol g À 1 at 298.15 K and 5 bar pressure and excellent stability. When the activation temperature was at 600°C, such NPC exhibited a superior electrochemical performance as anode for supercapacitors with a specific capacitance of 158.8 and 113 F g À 1 in 6 M KOH at a current density of 1 and 10 A g À 1 , respectively. Notably, it delivered an excellent stability with capacity retention of 97.4 % at 20 A g À 1 after 6000 cycles.
