“…[10] The other advantage of the HS-liquid for gas separation comes from the presence of the empty cavities ( Figure 5 a), which essentially provide very high fractional free volume to enhance gas diffusivity through the porous liquid. [11] The introduction of hollow structures into a dense polymeric matrix can increase gas diffusivity because the empty cavities essentially provide free space for gas transport, reducing the gas diffusion pathway in the liquid state. To examine this effect, the HS-liquid was supported in a polymeric membrane and the gas separation performance was measured for the separation of CO 2 and N 2 ( Figure 5).…”

A porous liquid containing empty cavities has been successfully fabricated by surface engineering of hollow structures with suitable corona and canopy species. By taking advantage of the liquid-like polymeric matrices as a separation medium and the empty cavities as gas transport pathway, this unique porous liquid can function as a promising candidate for gas separation. Moreover, such a facile synthetic strategy can be further extended to the fabrication of other types of nanostructure-based porous liquid, opening up new opportunities for preparation of porous liquids with attractive properties for specific tasks.

“…Furthermore, the ether groups contained in the canopy chains, in principle, can enhance the gas solubility and selectivity towards CO 2 via Lewis acid/base interactions, making the HS‐liquid a suitable candidate for CO 2 capture 10. The other advantage of the HS‐liquid for gas separation comes from the presence of the empty cavities (Figure 5 a), which essentially provide very high fractional free volume to enhance gas diffusivity through the porous liquid 11. The introduction of hollow structures into a dense polymeric matrix can increase gas diffusivity because the empty cavities essentially provide free space for gas transport, reducing the gas diffusion pathway in the liquid state.…”

“…The viscosity was decreased down to about 8,000 and 500 cP for 15 and 70 wt% water contents, respectively. It was also found that water, while decreasing the CO2 capture capacity, significantly helped reducing the viscosity of the NOHMs, thereby enhancing CO2 diffusion (Petit et al, 2013a).…”

CO2 capture by amine scrubbing, which has a high CO2 capture capacity and a rapid reaction rate, is the most employed and investigated approach to date. There are a number of recent large-scale demonstrations including the Boundary Dam Carbon Capture Project by SaskPower in Canada that have reported successful implementations of aqueous amine solvent in CO2 capture from flue gases. The findings from these demonstrations will significantly advance the field of CO2 capture in the coming years. While the latest efforts in aqueous amine solvents are exciting and promising, there are still several drawbacks to amine-based CO2 capture solvents including high volatility and corrosiveness of the amine solutions as well as the high parasitic energy penalty during the solvent regeneration step. Thus, in a parallel effort, alternative CO2 capture solvents, which are often anhydrous, have been developed as the third-generation CO2 capture solvents. These novel classes of liquid materials include ionic liquids, CO2triggered switchable solvents (i.e., CO2-binding organic liquids, reversible ionic liquids), and nanoparticle organic hybrid materials. This paper provides a review of these various anhydrous solvents and their potential for CO2 capture. Particular attention is given to the mechanisms of CO2 absorption in these solvents, their regeneration and their processability-especially taking into account their viscosity. While not intended to provide a complete coverage of the existing literature, this review aims at pointing the major findings reported for these new classes of CO2 capture media.
