摘要：Potential of porous carbons for practical applications is often limited by their intrinsic fragility and poor processability. Here, a facile approach to fabricate hierarchically macro-/microporous carbon monolith (CM) with high strength and integrated structure is developed, which offers great possibilities for structure-to-functionality applications. Through a fiber-reinforced sol-gel process and an ambient pressure drying approach, aerogel-like CMs can be designed and fabricated in customizable forms. In particular, a novel scroll-type carbon monolith (S-CM) is constructed, which can mimic a roll-to-roll tube reactor and thus avoid the packing problems arising from the granules or powders of conventional activated carbons. The resulting CM exhibits a high CO2 adsorption capacity of 15.9 mmol g(-1) at 25 bar and a breakthrough capacity of 1 mmol g(-1) at 1 bar. Moreover, owing to the integrated structure and good electrical conductivity, the scroll-type S-CM can be easily regenerated by employing a low-energy electrothermal desorption technique. The specialized design of the CMs should fulfill industrial directives and may provide an access route to more efficient porous carbons for structure-oriented and process-intensified applications.
