Summary: For the first time, amino acid groups were added to Fe3O4 nanoparticles to enhance CO2 absorption and desorption. The modified nanoparticles showed higher stability and presence of amino groups, resulting in increased CO2 absorption capacity. Moreover, Fe3O4@arginine, Fe3O4@histidine, and Fe3O4@glycine nanofluids significantly improved CO2 desorption enhancement.

Summary: We developed a thermochemical model to evaluate the CO2 regeneration energies in aqueous solutions of MEA, DEA, AMP, and IPAE. The regeneration heat includes reaction heat, sensible heat, and vaporization heat. We calculated the reaction heat using our model and determined the concentrations of all chemical species in the CO2 absorption and release states. The contribution of protonation reaction is significant in sterically hindered amines AMP and IPAE, while both protonation and carbamate hydrolysis play important roles in MEA and DEA. Sensible heat dominates the regeneration heat compared to reaction and vaporization heats.

Summary: Increase in CO2 concentration in the atmosphere is a major concern for researchers. Chemical absorption, particularly using amines, has been found to be an effective method for CO2 capture. The absorption capacity of amines depends on various factors including reaction conditions and amine structure. This report reviews the structural dependence of amines on their absorption capacity and compares the effects of different structural changes.

Summary: This study provides a model for an LBM production plant that includes biogas upgrading and liquefaction, and investigates the optimization based on different objective function formulations. The results show that optimizing based on exergy and total annualized cost leads to similar solutions, as higher operating pressure is required to meet CO2 limitations. Additionally, the choice of refrigeration cycle has a greater impact on the overall performance of the LBM plant than the objective function formulation.

Summary: By harnessing the power of CaO- and SIL-engineered sorbents, high-performance and tunable sorbents in DAC of CO2 were developed. These sorbents exhibited high CO2 uptake capacity, rapid interaction kinetics, facile CO2 releasing, and stable sorption/desorption cycles. Operando DRIFTS analysis and solid-state NMR analysis demonstrated the critical roles of SIL species in low-concentration CO2 capture.

Summary: Several phase splitting systems have shown potential in reducing regeneration energy consumption for large-scale CO2 capture. This study investigated the phase splitting rules of primary/secondary amine-tertiary amine anhydrous systems and primary/secondary amine-tertiary amine-water systems, and identified factors that affect the phase splitting behavior.

Summary: The study compared the CO2 absorption capacity of three hybrid solvents based on [Bmim][OAc] and different cosolvents, with [Bmim][OAc]-DEPG250 showing the highest absorption capacity. The addition of DEPG250 significantly reduced the viscosity while maintaining comparable absorption capacity. Additionally, using [Bmim][OAc]-DEPG250 as a solvent resulted in a lower CO2 capture cost compared to aqueous amine solutions due to reduced utility costs.

Summary: The study developed hydrogel materials suitable for DAC applications, with high gas permeability, fast uptake kinetics, and minimal performance degradation after recycling. Introduction of high-boiling-point/nonaqueous solvent systems significantly improved recyclability of the materials. Incorporating different amines/solvents into hydrogel platforms allowed for controlled and significantly improved uptake kinetics.

Summary: The study determined the equilibrium constant K-ch values of carbamate hydrolysis reactions for both hindered amines and normal amines using a combination of C-13 NMR spectroscopy and chemical equilibrium analysis. The differences in properties between hindered amines and normal amines were revealed, with hindered amines showing negative Gibbs energy changes and normal amines showing positive changes. The obtained equilibrium constants and standard enthalpies will be useful for evaluating the performance of amine CO2 absorbents.

Summary: The study found that with a TEPA loading of 40wt% and a flow rate of 200mL.min(-1), the CO2 adsorption capacity reached optimal value. ADS-17-40%TEPA exhibited good reversibility, with the CO2 adsorption capacity remaining nearly stable after two adsorption-desorption cycles.

Summary: This study presents an electrochemical direct air capture (DAC) method using air-stable redox couple of neutral red, which requires a minimum energy requirement of 65 kJ(e)/mol(CO2). Direct air capture of carbon dioxide is a viable option for mitigating CO2 emissions and their impact on global climate change.

Summary: This study investigates the effect of using water as a low-viscosity component in ternary amine-based deep eutectic solvents (DESs) on their physicochemical properties, thermal stability, and CO2 absorption capacity. The results show that adding small amounts of water can significantly decrease the viscosity of DESs while maintaining high CO2 absorption capacity and thermal stability.

Summary: The study found that amine-infused hydrogel (AIH) particles can efficiently capture CO2 and have a higher CO2 uptake capacity compared to traditional MEA solution. The kinetic performance for CO2 absorption was investigated under different conditions, showing that temperature, mixing, and additives affect the CO2 absorption performance of AIH particles. AIH particles tend to agglomerate without mixing, leading to decreased CO2 absorption capacity, but remain separated and show increased CO2 uptake when mixed with the gas mixture. Additional decane and dodecyltrimethylammonium bromide (DTAB) can alleviate particle coagulation and enhance both CO2 absorption rate and capacity.
