Direct air capture (DAC) is an emerging negative CO2 emission technology that aims to introduce a feasible method for CO2 capture from the atmosphere. Unlike carbon capture from point sources, which deals with flue gas at high CO2 concentrations, carbon capture directly from the atmosphere has proved difficult due to the low CO2 concentration in ambient air. Current DAC technologies mainly consider sorbent-based systems; however, membrane technology can be considered a promising DAC approach since it provides several advantages, e.g., lower energy and operational costs, less environmental footprint, and more potential for small-scale ubiquitous installations. Several recent advancements in validating the feasibility of highly permeable gas separation membrane fabrication and system design show that membrane-based direct air capture (m-DAC) could be a complementary approach to sorbent-based DAC, e.g., as part of a hybrid system design that incorporates other DAC technologies (e.g., solvent or sorbent-based DAC). In this article, the ongoing research and DAC application attempts via membrane separation have been reviewed. The reported membrane materials that could potentially be used for m-DAC are summarized. In addition, the future direction of m-DAC development is discussed, which could provide perspective and encourage new researchers’ further work in the field of m-DAC.

“…Recently, it has been demonstrated that (NHC)Pd-based systems cat-alyze vinyl-addition polymerization of various functionalized norbornenes [14][15][16][17][18][19][20][21]. For instance, these systems showed good catalytic activity in polymerization of norbornenes with hydroxy [20,22], ether [21], ester [14,15,[18][19][20]23,24], imide [14,16,17], silyl [14,19,20,24], and alkyl/alkenyl [19,20,22,24,25] functionality. At the same time, to the best of our knowledge, the polymerization of norbornene-type monomers with reactive halogen-containing groups over (NHC)Pd-catalysts has not yet been reported.…”

Vinyl-addition polynorbornenes are of great interest as versatile templates for the targeted design of polymer materials with desired properties. These polymers possess rigid and saturated backbones, which provide them with high thermal and chemical stability as well as high glass transition temperatures. Vinyl-addition polymers from norbornenes with bromoalkyl groups are widely used as precursors of anion exchange membranes; however, high-molecular-weight homopolymers from such monomers are often difficult to prepare. Herein, we report the systematic study of vinyl-addition polymerization of norbornenes with various bromoalkyl groups on Pd-catalysts bearing N-heterocyclic carbene ligands ((NHC)Pd-systems). Norbornenes with different lengths of hydrocarbon linker (one, two, and four CH2 groups) between the bicyclic norbornene moiety and the bromine atom were used as model monomers, while single- and three-component (NHC)Pd-systems were applied as catalysts. In vinyl-addition polymerization, the reactivity of the investigated monomers varied substantially. The relative reactivity of these monomers was assessed in copolymerization experiments, which showed that the closer the bromine is to the norbornene double-bond, the lower the monomer’s reactivity. The most reactive monomer was the norbornene derivative with the largest substituent (with the longest linker). Tuning the catalyst’s nature and the conditions of polymerization, we succeeded in synthesizing high-molecular-weight homopolymers from norbornenes with bromoalkyl groups (Mn up to 1.4 × 106). The basic physico-chemical properties of the prepared polymers were studied and considered together with the results of vinyl-addition polymerization.

The development of polymers with high separation characteristics for the efficient removal of carbon dioxide from bio‐/natural gases is the key to reducing the environmental impact of CO2. In this work, preparation and gas‐separation properties of novel vinyl‐addition polynorbornenes containing oxirane‐moieties at spiro centers, which combine high CO2‐permeability with remarkable selectivities for separation of CO2 from its mixtures with nitrogen and methane are published. Gas permeability data of the epoxidized polymer based on 5‐ethylidene‐2‐norbornene exceed the Robeson upper bound of 2019 for the CO2/N2 system (CO2 permeability is 1000 Barrer, α(CO2/N2) = 67)). Separation experiments with mixtures of gases confirm the high separation performance of this polymer. In particular, the data for CO2/CH4 separation are above or close to the upper bound of 2018 for mixed gases. A similar effect of introducing oxirane moieties into spiro centers is also shown for another vinyl‐addition polymer derived from 5‐isopropylidene‐2‐norbornene and is not observed for a related polymer bearing oxirane moieties at the ends of side chains. A simple synthesis of the epoxidized polymer from available 5‐ethylidene‐2‐norbornene, combined with high CO2‐permeability and selectivities, may open a window for industrial applications of this polymer in important membrane processes, in particular, for natural/biogas upgrading.
