Hierarchical porous graphene-based carbons prepared by carbon dioxide activation and their gas adsorption properties

Facile one-pot synthesis of magnetic nitrogen-doped porous carbon for high-performance bilirubin removal from BSA-rich solution

“…It is evident that the m-NpC shows a continuous increased N 2 adsorption with a combined feature of type IV and type II isotherms, indicating the co-presence of mesopores and macropores. 36 Moreover, H 2 hysteresis loop at relative pressure (P/P 0 ) above 0.4 is also clearly observed, indicating its cylindrical pores with nonuniform shape.…”

“…2b with respect to the highly transparent texture and crumpled-sheet morphology, which is consistent with the SEM morphology of previously reported graphene material. 36 In general, the carbonization of biomass results in the formation of carbon blocks rather than carbon nanosheets. In this work, the addition of a lot of NaCl might provide sufficient solid surface to direct the formation of chitosan coating, which resulted in the occurrence of a two-dimensional nanostructure aer carbonization.…”

The impact of surface chemistry and texture on the CO2 uptake capacity of graphene oxide

“…Whilst the work on this topic is still limited [20,21], there is a prevalence in the literature of GO powders prepared using the classical Hummer's method. Overall, claims of their CO 2 uptake capacity have been markedly disappointing (<1 mmol g −1 ) [16,[22][23][24]. Possible explanations are the limited accessible surface area (commonly <100 m 2 g −1 , cf.…”

Simple energy barrier for component mixture of natural gases

“…In the paper [6] activated graphene-based carbon showing excellent gas storage properties with an exceptionally high performance is considered. In [7] the experimental data on gas sorption which showed significant opportunities of hierarchical porous graphene-based carbons (HPGCs) for СО2 и Н2 adsorption are given. In order to simulate the movement of molecules in porous space spherical nanoparticles have been converged to the distance of one or several nanometers and the ability of test molecules to get through this gap has been investigated.…”
