“…Thus, a range of nucleophilic reagents, including neutral N -heterocyclic carbenes [ 25 , 26 ], are known to react with CO 2 even under mild conditions, and some chemistry at transition metal centers is provided by the possibility of CO 2 insertion into the bond between a metal atom and a suitable anionic ligand, e.g., alkyl, allyl, alkoxide and hydride [ 27 , 28 , 29 , 30 , 31 , 32 ]. In this context, amines are key reactants towards carbon dioxide, and indeed carbon dioxide/amine systems have been intensively investigated in the field of capture/storage [ 33 , 34 , 35 ] and exploited for the incorporation of the CO 2 moiety within organic structures [ 36 , 37 , 38 , 39 ]. Furthermore, CO 2 is also prone to insertion reactions into a variety of metal-amide bonds, generating a carbamato ligand; however, metal complexes containing carbamato ligands are easily available through diverse synthetic routes not requiring the use of pressurized CO 2 .…”

“…The advantage of using alkanolamine solutions is the reversibility of carbon dioxide binding, which makes it possible to regenerate the absorbent at temperatures up to 120-140°C [81]. Despite the development of other approaches to trapping carbon dioxide, the constant development and improvement of amine purification (in terms of the development of new amine absorbents, process parameters, and instrumentation) allows us to expect the demand for this process in industry and power engineering in the coming decades [80][81][82][83][84][85][86][87].…”

The deteriorating environmental situation has stimulated the world community to develop research related to the decarbonization of the economy and hydrogen energy. These two areas are essentially focused on membrane technologies, which play a crucial role in solving key tasks for these areas. This review is devoted to this research. The first part describes various membrane technologies aimed at capturing CO 2 from the most common gas mixtures, primarily containing nitrogen, methane, and hydrogen. In recent years, studies related to the amine purification of CO 2 , including membrane technologies, and the use of porous membranes filled with ionic liquids has also been intensively developed. Electromembrane technologies are also being developed that allow not only capture of CO 2 but also to process it into fuel or valuable chemicals. The course taken by several developed countries, including Russia, for the development of hydrogen energy includes the production, purification of hydrogen, and its conversion into energy. It should be noted that membrane technologies are fundamentally important for the development of each of these areas. Thus, the evolution of hydrogen is possible with the use of polymer membranes, and for deep purification and production of high-purity hydrogen by membrane catalysis; membranes based on palladium alloys are used. Finally, fuel cells are developed to produce energy from hydrogen, the most important part of which are proton or oxygen-conducting membranes.

“…Pre-combustion capture, post-combustion capture, and oxy-fuel combustion are the main technologies to mitigate CO 2 emissions in fossil fuel combustion, and post-combustion capture is widely used owing to no large-scale reconstruction of existing facilities. For post-combustion capture, although chemical absorption by aqueous amine solutions enables fast CO 2 capture kinetics and high adsorption capacities, outstanding issues limit its application. , It is energy-intensive and expensive for use in large-scale CO 2 separation in addition to being corrosive and toxic in nature . Alternatively, adsorption by porous solid adsorbents is considered a sustainable approach for capturing CO 2 from flue gases .…”

Mesoporous MgO is a promising candidate for CO 2 capture. In this study, MgO pellets were activated via hydration and the effects of the process on the texture, structures, and CO 2 adsorption properties of the pelletized MgO adsorbents were systematically studied. Two adsorption kinetics models were used to investigate the CO 2 adsorption kinetics of the pelletized MgO adsorbents. Simultaneously, their kinetic parameters and the influence of adsorption temperatures were determined. It was found that a 3D, flaky, inter-connected network structure appeared after hydration. The hydration process significantly improved the pore structure of the adsorbent and thereby improved the CO 2 adsorption capacity and equilibrium rate constant. The increase in CO 2 adsorption capacity was attributed to the development of their structure rather than the reaction of Mg(OH) 2 with CO 2 . The results of a kinetics study showed that a pseudo-second-order model was suitable for predicting the entire adsorption process. Meanwhile, the equilibrium kinetics rate constant of CO 2 capture increased with adsorption temperature, but the initial adsorption rate was mainly related to the texture and structures of the adsorbents. Consequently, hydration by steam or liquid water was deemed an effective method for improving the adsorption performance of MgO pellets, and the hydrated adsorbents were suitable for use in practical CO 2 capture.
