Graphene and its tailoring as emerging 2D nanomaterials in efficient CO2 absorption: A state-of-the-art interpretative review

Separation of CO2/CH4 gas mixtures using nanoporous graphdiyne and boron-graphdiyne membranes: influence of the pore size

“…with a similar equation for CH 4 . The main difference between the BGY and BGDY substrates is that it becomes difficult to place a second molecule on top of the same hole of GDY, because the hole is small.…”

“…The purification of natural gas and landfill gas, and the biogas upgrading 2 through the separation of CO 2 from the CO 2 /CH 4 mixtures, a process that improves their energy content, have acquired great relevance in the last years. A large variety of technologies and sorbents are being actively investigated 3,4 to improve the efficiency of more conventional sorbents based on zeolites and activated carbons. Among them, membrane-based technologies [5][6][7] offer many advantages, since they are easy to implement, scalable and energy efficient.…”

“…13 In this context, nanomaterials show attractive characteristics. 4 Mazri et al have reviewed the application of graphene and graphene-based nanofluids for CO 2 absorption 4 Gas separation is the central process on all these technologies. Therefore, abundant, cheap, recyclable filtering materials provide the key for the widespread use of these technologies.…”
