Abstract
Carbon monoliths of ultrahigh pore volume (5.35 cm(3) g(-1) ) and high surface area (2700 m(2) g(-1) ) accommodate a record high level of amine(tetraethylenepentamine), up to 5 g g(-1) within its hierarchically networked micro-/mesopores over a wide range. Thus, this solid-amine@carbon shows exceptional CO2 sorption and stable cyclic capacities at simulated flue-gas conditions.
摘要
具有超高孔体积（5.35 cm³ g⁻¹）和高比表面积（2700 m² g⁻¹）的碳整体式材料可容纳创纪录高水平的胺（四乙烯五胺），在很宽的范围内，其分级网络的微孔/介孔中可达 5 gg⁻¹。因此，这种固胺@碳在模拟烟道气条件下表现出优异的 CO2 吸附和稳定的循环容量。
