So, it is necessary to develop a more feasible CCS technology. The application of porous materials in the capture and storage RAD001 of CO2 has a big potential and wide prospect. There are many kinds of porous materials that can be used as CO2 adsorbents, such as molecular sieves,

porous silica, metal organic frameworks (MOFs), and porous carbons [8–18] due to their attractive properties such as high specific surface area and highly developed pore structure. Among these porous materials, porous carbons are especially attractive because they are inexpensive, easy to regenerate, and not sensitive to moisture which may compete with CO2 when adsorption happens [19–21]. However, it is hard

for pristine porous carbon materials without any modification to reach high CO2 uptake values [22]. As a result, researchers modified Quisinostat cost the surface of porous carbon with nitrogen-containing functional A-1155463 price groups [23], which enhanced the CO2 adsorption capacity of these porous carbon materials. For example, Chandra et al. synthesized a kind of N-doped carbon by chemical activation of polypyrrole functionalized graphene sheets. This kind of carbon material showed a CO2 uptake of 4.3 mmol g−1 with high selectivity at 298 K under 1 atm [24]. Zhou et al. prepared a series of N-doped microporous carbons using zeolite NaY as a hard template and furfuryl alcohol/acetonitrile as carbon precursors. The CO2 adsorption capacity of as-prepared

N-doped carbons was much higher than that of the template carbons without N-doping [25]. Nandi et al. prepared a series of highly porous N-doped activated carbon monoliths by physical activation. The monoliths exhibit an Vasopressin Receptor excellent CO2 uptake of up to 5.14 mmol g−1 at ambient temperature and 11.51 mmol g−1 at 273 K under atmospheric pressure [26]. Wu et al. synthesized a series of nitrogen-enriched ordered mesoporous carbons via soft-template method. The CO2 adsorption capacity of nitrogen-enriched carbon is higher than that of pristine material due to the presence of nitrogen-containing functionalities [27]. Sevilla et al. prepared a series of N-doped porous carbons using KOH as activation agent and polypyrrole as carbon precursor. The excellent CO2 uptakes of these carbons were ascribed to the abundant micropores with the pore size around 1 nm and the presence of basic N-containing groups [19]. Hao et al. synthesized a kind of nitrogen-containing carbon monolith through a self-assembled polymerization of resol and benzoxazine followed by carbonization. The high CO2 adsorption capacity was attributed to the N-containing groups of the resulting carbons [21].
