摘要：Hierarchical nitrogen-enriched porous carbon containing micropores, mesopores, and macropores were prepared by a nanocasting pathway using a Schiff base precursor and SBA-15 as the hard template. The specific surface area and pore volume of the obtained porous carbon are 752 m(2).g(-1) and 0.79 cm(3).g(-1), respectively. The nitrogen content is as high as 7.85% (w). The porous carbon shows a CO2 capacity of 97 cm(3).g(-1) at ambient pressure and 273 K. The CO2/N-2 and CO2/CH4 separation ratios (molar ratios) are accordingly 7.0 and 3.2, and the Henry's low pressure selectivities are 23.3 and 4.2, respectively. CO2 adsorption tests confirmed that the micropores play a dominant role and nitrogen-containing functional groups play a synergistic role. The predicted ideal adsorbed solution theory (IAST) selectivities of the two-component mixed stream are 40 (CO2/N-2) and 18 (CO2/CH4) by Toth mode simulation.
