Summary: Waste-derived activated carbon from tea biomass is found to be an effective sorbent for CO2 capture, exhibiting higher capacity compared to commercial activated carbon. By incorporating SiO2 nanoparticles, the fluidization performance of the sorbent is improved, resulting in better CO2 capture efficiency and multicyclic stability.

Summary: Electrochemical CO2 capture methods have attracted attention for their low energy demands, but combining electrochemical and CO2 mass-transfer reactor units may increase process time. In contrast, optimizing solution chemistry can improve both energy demands and process time simultaneously.

Summary: Tertiary amines are used as alternative absorbents for carbon capture, but their slow absorption rate increases costs and limits large-scale application. Carbonic anhydrase as a homogeneous catalyst can accelerate CO2 absorption in aqueous tertiary amines, significantly improving the reaction rate.

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.

Summary: The CO2 chemical absorption-microalgae conversion (CAMC) system combines the advantages of chemical absorption and biological methods to achieve simultaneous low-energy CO2 capture and green resource application. This study evaluated the effects of adding tertiary amine TEMDA and space hindered amine DACH to the CAMC system and found that the addition of TEMDA increased cell concentration and growth rate, as well as carbon conversion efficiency and sequestration capacity.

Summary: Air quality has a significant impact on people's health, especially in buildings with closed air conditioning systems. A modified carbon dioxide sorbent based on alumina was developed for indoor direct air capture of CO2, demonstrating good adsorption capacity and exhaustion indication. Besides, the exhausted sorbents can be regenerated and reused using a conventional microwave oven.

Summary: Amine functionalized solid sorbents prepared by treating geopolymer with nitric acid showed superior pore structure and surface texture for efficient CO2 capture. The increase in silanol density and amine grafting amount were found to be correlated with the CO2 capture performance of the sorbent.

Summary: The study demonstrates the facile preparation of dry amine CO2 sorbents through a cost-effective and environmentally friendly pathway. Results show that the TEPA/SiO2 sorbents exhibit excellent CO2 capture performance, with the 50TEPA/SiO2 sorbent showing higher CO2 uptake and lower mass transfer resistance. Due to their low cost and ease of preparation, dry amine sorbents may have potential applications for urgent situations such as SO2 or H2S leaks.

Summary: Directly capturing CO2 from the air at ambient conditions is challenging due to the competition of water adsorption and low CO2 pressure. In this study, we developed amine-functionalized quasi-metal-organic frameworks (X-UIO-EDA) with high CO2 capture capacity, and discovered that water-assistance enhances CO2 capture under 400 ppm CO2 and humidity. The results showed that 2-UIO-EDA had a 10-fold higher CO2 capture capacity under humid air conditions compared to dry air conditions, and quasi-UIO-66 had more amine modification sites for higher CO2 capture.

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.
