“…ZIFs, which has the imidazole as the building unit and M-Im-M as linkages, have been investigated as analogous to MOF due to their identical topology. ZIFs have the advantages of both MOF and zeolites, and have a greater potential than MOFs in CCS as they possess zeolite-like structure, higher thermal and chemical stability, and better water resistance [150,151]. Although the CO2 capacity of MOFs is much higher than ZIFs, the ZIFs have a better CO2 selectivity over water.…”

CCS, Carbon Capture and Storage, is considered a promising technology to abate CO2 emissions from point sources. The present review deals with the principle of postcombustion capture techniques, including thermal or pressure swing principles, adsorption or absorption, and electrical swing or membrane separation processes.Opportunities and challenges are assessed. In the first section of absorption processes, several commercial technologies are compared, and complemented by the aqueous or chilled ammonia (NH3) process, and a dual or strong alkali absorption. The second section deals with adsorption where fixed beds, circulating fluidized beds and countercurrent bed configurations will be discussed, with special focus on the different adsorbents ranging from zeolites or activated carbon, to more complex aminefunctionalized adsorbents, nanotubes or metal organic frameworks (MOFs), and alkali-

“…Though, insufficient but comparatively constant amine graing offers a sterically advanced structure for more amine impregnation to deliver high effective sorbents. 118 For example, Son et al 119 used a sequence of mesoporous silica adsorbents, SBA-16, SBA-15, MCM-41, MCM-48, and KIT-6, and functionalized them with 50 wt% PEI loading in methanol to assess the CO 2 adsorption performance. PEI loaded KIT-6 (6 nm size pores) showed 135 mg g À1 CO 2 adsorption in a stream at 358 K, against a similar amount of PEI loaded MCM-41 (2.8 nm pore size) with 111 mg g À1 , and their adsorptiondesorption kinetics are shown in Fig.…”

Confinement of $$\hbox {CO}_{2}$$ inside carbon nanotubes

We propose a preliminary study based on molecular dynamics calculations to investigate the adsorption of pure $$\hbox {CO}_{2}$$ CO 2 on flexible single-walled carbon nanotubes (SWCNTs) of different sizes. The adsorption capacities of SWCNTs were simulated and the effect of chirality and diameter of SWCNTs was assessed, to check them as sizable carbon structured materials suitable for $$\hbox {CO}_{2}$$ CO 2 confinement and storage. The potential energy surfaces, describing the intermolecular interactions involving $$\hbox {CO}_{2}$$ CO 2 -SWCNT and $$\hbox {CO}_{2}$$ CO 2 -$$\hbox {CO}_2$$ CO 2 pairs, have been described specifically by adopting the improved lennard jones model potential. The intramolecular interactions within the SWCNT were considered explicitly since they are responsible for out-of-plane movements of carbon atoms and the flexibility of nanotubes. These well-formulated potentials are well capable of defining $$\hbox {CO}_{2}$$ CO 2 confinement through physisorption and guarantee a quantitative description and realistic results for the dynamics of the interactions. The flexible SWCNTs can adsorb up to 35 wt% at 273 K, a property that makes them potentially versatile materials competitive with other carbon-derived adsorbents to cope with $$\hbox {CO}_{2}$$ CO 2 gas emission.
