采用离子液体碳化法制备了高氮含量的氮掺杂多孔炭。通过在130 ℃下在流动蒸汽、纯CO2、干燥空气和干燥SO2中处理来研究N-碳的水热和化学稳定性。处理前后的CO2吸附测量结果表明，即使在如此苛刻的条件下，与典型的吸附-解吸循环相比，发现N-碳是一种非常稳定的CO2捕获材料。
Nitrogen-doped porous carbon (N-carbon) with high nitrogen content was synthesized by carbonization of an ionic liquid. The hydrothermal and chemical stability of N-carbon was investigated by treatment in flowing steam, pure CO2, dry air, and dry SO2 at 130 degrees C. CO2 adsorption measurements before and after the treatments showed that, even under such severe conditions, in comparison to typical adsorption-desorption cycling, N-carbon was found to be a remarkably stable material for CO2 capture.
