“…The substitution of linkers or metal ligands as well as synthesis techniques have all been explored as potential modifications to MOFs. , Pore size/volume and surface dependence govern CO 2 absorption through MOFs. A 2-D square grid MOF (SIFSIX-3-Cu) with a silicon hexafluoride anions-connected pyrazine/copper(II) was built to improve CO 2 absorption and selectivity at a very low partial pressure pertinent to DAC. , When SIFSIX-3-Cu (1.24 mmol/g) is used, a significant CO 2 absorption is seen at 298 K adsorption temperature and 0.4 mbar partial pressure . The ability of this substance to physically collect CO 2 from sources with extremely low CO 2 concentrations, like air, is made possible by fine-tuning the pore size and interaction energy.…”

Climate change has been linked to industrial and commercial activities caused by exploitation of fossil fuels for energy needs for over a century now. A significant rise in greenhouse gas (GHG) emissions, majorly CO 2 , has been reported in the last few decades. Global climate change necessitates mitigation of atmospheric CO 2 levels to suitable margins using CO 2 capture mechanisms. Direct air capture (DAC) technology is the most efficient way to mitigate or reduce greenhouse emissions by capturing carbon dioxide directly from the atmospheric air. It is imperative that DAC technology be ramped up quickly in order to meet the climate goal to reduce global temperature rise below 2 °C in the next 30 years. This review focuses on the specifics of various techniques, pilot projects, and commercial facilities for DAC technology deployment. DAC has seen substantial technical improvement in recent years, with commercial firms already functioning in the industry with significant upmarket potential. There are about 19 DAC plants in operation across the world, absorbing around 0.01 Mt CO 2 /year. This review article discusses the various DAC technologies used by the companies, future potential, life cycle assessment, as well as the economic viability of worldwide installation of these facilities. The paper provides details on the application of various sorbents including nanomaterials for current advances in DAC. Lastly, the outlook and perspectives are also presented with the concluding remarks.

“…2,5,6 Generally, direct air capture and conversion (DACC) processes are limited to thermodynamic stability of CO 2 , which puts up a major synthetic challenge for its conversion under mild conditions. 7,8 The production of cyclic carbonates from CO 2 is very interesting from a sustainability point of view due to the high atom economy of the reaction, since it presents complete atomic efficiency. Cyclic carbonates are important industrial products that have been widely applied as polar aprotic solvents, organic synthesis intermediates, electrolytes in lithium-ion batteries, cosmetic formulations, and monomers, contributing in over 90 billion to the EU economy within these sectors.…”

“…Thus, chemisorbent materials (e.g., amines or hydroxides) have proven to be much more effective for the DAC processes . This renders thermodynamically stable adducts (e.g., carbamates and carbonates), which require large amounts of energy to recover the CO 2 or low added-value products (e.g., CaCO 3 ). − A finely balanced interaction between the CO 2 and the sorbents is required to enable its capture and, subsequently, transformation into added-value products. ,, Generally, direct air capture and conversion (DACC) processes are limited to thermodynamic stability of CO 2 , which puts up a major synthetic challenge for its conversion under mild conditions. , …”

Direct air capture and integrated conversion is a very attractive strategy to reduce CO2 concentration in the atmosphere. However, the existing capturing processes are technologically challenging due to the costs of the processes and the low concentration of CO2. The efficient valorization of the CO2 captured could help overcome many techno-economic limitations. Here, we present a novel economical methodology for direct air capture and conversion that is able to efficiently convert CO2 from the air into cyclic carbonates. The new approach employs commercially available basic ionic liquids, works without the need for sophisticated and expensive co-catalysts or sorbents and under mild reaction conditions. The CO2 from atmospheric air was efficiently captured by IL solution (0.98 molCO2/molIL) and, subsequently, completely converted into cyclic carbonates using epoxides or halohydrins potentially derived from biomass as substrates. A mechanism of conversion was evaluated, which helped to identify relevant reaction intermediates based on halohydrins, and consequently, a 100% selectivity was obtained using the new methodology.

“…5 As a result, the DAC technology plays a crucial role in mitigating emissions from difficult-to-decarbonize sectors such as aviation, shipping, and remote industries. 6 However, the efficiency and costeffectiveness of DAC are impeded by the low atmospheric CO 2 concentration (approximately 440 ppm), 7 which is significantly less than the concentrations (10−20 vol %) 8 emitted from stationary sources. As a result of the masstransfer bottleneck caused by low atmospheric CO 2 concentrations, present DAC procedures consume a lot of energy.…”

Direct air capture (DAC) represents a promising technology for mitigating climate change by extracting CO 2 from the atmosphere. This study introduces a novel application for effective CO 2 capture from dispersed emission sources, integrated with a liquid electrolysis system to improve capture cycle efficiency. By focusing on distributed sources, the DAC application overcomes the constraints of traditional stationary CO 2 capture methods. It employs a thin-layer moving bed spray and air convection to capture CO 2 in lean liquid, which converts into rich trap liquid when the carbonate concentration exceeds a certain threshold. Electrolysis is then used to recover the lean liquid. This design allows for quick, energy-efficient CO 2 absorption even under low partial pressure conditions (462 ppm). The technology is designed to facilitate significant CO 2 capture while concurrently generating high-purity hydrogen and collecting carbon dioxide. By reusing the capture liquid, an integrated capture and desorption process is realized. In a test with 1 M KOH as a lean trap solution and a wind speed of 9 m/s, a rich trap solution was obtained after 13 h, lowering the CO 2 concentration at the outlet by 97 ppm compared to the input air, demonstrating the device's effectiveness.
