Summary: Electrochemical CO2 conversion into fuels or chemicals and CO2 capture from point or dilute sources are two important processes to address the gigaton challenges in reducing greenhouse gas emissions. Both processes are energy intensive, but synergistic coupling between them can improve energy efficiency and reduce costs, by eliminating the need for CO2 transport and storage or capture media regeneration.

Summary: In this study, a novel four-component phase change absorbent system was designed, which showed great potential for low energy-consuming CO2 capture. By adding [Bmim][BF4] as a promoter, the absorption/desorption performance and phase separation capability were improved, leading to reduced regeneration energy consumption. The energy consumption of this absorbent could be reduced to 2.06 GJ center dot t(-1) CO2, which was 45.8% less than that of 30 wt% MEA.

Summary: Ionic liquids (ILs) are well-known for their CO2 capture properties. The combination of ILs with various materials reduces the problem of high viscosity of ILs. Encapsulated ionic liquid (ENIL) systems can overcome the low CO2 absorption rate and difficulties in solvent regeneration. This review comprehensively evaluates recent literature on ENILs for CO2 capture, including preparation, characterization, reaction kinetics, solubility, selectivity, and regeneration studies.

Summary: This study presents a new approach for the synthesis of water-dispersible core-shell nanocatalysts using metal-organic frameworks (MOFs). By introducing functionalized nanoclusters during the self-assembly of MOFs, missing-linker deficiencies are induced to fabricate mesoporosity. The resulting nanocatalysts significantly reduce the energy consumption of CO2 capture and achieve a 10-fold improvement in efficiency compared to conventional catalysts.

Summary: In this study, the use of N,N-dimethylcyclohexylamine as a switchable-hydrophilicity solvent for the absorption of toluene showed excellent performance in separation processes. By bubbling CO2 and N-2, efficient desorption and separation were achieved, and the absorption capacity of the solvent remained comparable even after multiple cycles. This innovative and reversible remediation strategy utilizing switchable-hydrophilicity solvents has the potential to be a more environmentally friendly and energy-efficient alternative to traditional absorbents for reducing VOC pollution.

Summary: Carbon dioxide capture through solvent absorption in packed columns has shown potential for mitigating CO2 emissions from coal-fired power plants. Parameters such as packing types, solvent properties, and operating conditions can influence the efficiency of CO2 capture in packed columns. By using a design of experiments method and multiphase computational fluid dynamics, the impact of random packed column parameters on liquid holdup and interfacial area can be efficiently investigated. Sensitivity analysis indicates that the solvent flow rate and contact angle are key factors affecting liquid holdup and interfacial area, while solvent viscosity has minimal impact on interfacial area. The sensitivity scores for each input parameter can guide the selection of dimensionless numbers for developing correlations of liquid holdup and interfacial area.

Summary: Ruthenium nanoparticles immobilized on an amine-functionalized polymer-grafted silica support can selectively catalyze the hydrogenation of bicyclic heteroaromatics. The addition of CO2 to the hydrogen gas phase can effectively shut down the arene hydrogenation reaction while maintaining activity for heteroaromatic hydrogenation. This selectivity switch is achieved through the catalytic generation of ammonium formate species on the material's surface by hydrogenation of CO2. By altering the composition of the feed gas, a variety of benzofuran and quinoline derivatives can be selectively hydrogenated to fully or partially saturated products using a single catalyst.

Summary: PDO can be produced by fermenting glycerol, but separating it from the aqueous medium is difficult. A new method called Solvent-Assisted Switchable Water (SASW) is proposed. In this method, a hydrophilic solvent is used to extract PDO from water, while a CO2-switchable ionogen prevents the solvent from merging with the aqueous phase. The extraction yield was 73%, but the extracted PDO contained water and amine, indicating that further improvement is needed for selective extraction.

Summary: CO2-responsive materials undergo changes in their properties when CO2 is introduced or removed. CO2 is advantageous as a stimulus due to its abundance, benign nature, affordability, and lack of accumulation in a system. Various CO2-responsive materials such as polymers, latexes, surfactants, and catalysts have been explored. CO2-responsive gels, a subset of CO2-responsive polymers, have unique changes such as swelling or transformed morphology. This paper reviews the preparation, properties, and applications of CO2-responsive gels, including nanogels, microgels, aerogels, and macrogels, and also discusses CO2-induced self-assembled gels.

Summary: Switchable materials, especially CO2-switchable materials, are of great interest in environmental research. Replacing non-switchable materials with switchable counterparts has the potential to make processes more environmentally friendly by enhancing reusability and circularity, reducing energy costs and material consumption. This study focuses on the surface and foaming properties of aqueous solutions containing a non-switchable surfactant and a CO2-switchable additive. The results show that the additive can change surface properties, foamability, and foam stability when switched with CO2.

Summary: Volatile organic solvents are widely used in various industries, but their emissions, inhalation risks, and flammability pose significant concerns. Switchable-hydrophilicity solvents (SHS), which can switch between water-miscible and water-immiscible states, offer a solution to these issues. Anionic SHS (ASHS) systems, composed of hydrophobic carboxylic acid and water-soluble base, provide a new variation of SHS. This study reports the development of a low-toxicity SHS without the need for excess water, using branched carboxylic acids and substoichiometric amounts of NaHCO3 or NaOH.
