An Ultrahigh Pore Volume Drives Up the Amine Stability and Cyclic CO2 Capacity of a Solid-Amine@Carbon Sorbent

Abstract

Carbon monoliths of ultrahigh pore volume (5.35 cm3 g-1) and high surface area (2700 m2 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.
