Summary: Reactive carbon capture (RCC) is a promising solution for carbon capture and utilization. A systematic study found that RCC in aqueous environments is less effective and does not directly reduce into carbamate. Instead, the presence of amine solution suppresses the rate of CO formation while increasing that of H2.

Summary: Molten alkali metal borates have shown promise as high-temperature sorbents for CO₂ capture. In this work, we used borates to capture CO₂ and enable its electrolytic conversion into multiwalled carbon nanotubes (CNTs) as a sustainable alternative to conventional CNT synthesis techniques. Sodium lithium borate was found to achieve significantly higher CO₂ uptake capacities than alkali metal carbonate salts for CNT synthesis in the 550-650°C range.

Summary: Development of electrochemical pathways for converting CO2 into valuable products has been rapidly progressing in the past decade. A comparative life cycle assessment was conducted to evaluate one-step and two-step electrochemical conversion of CO2, revealing that the two-step electrosynthesis pathways are more compelling in terms of climate benefits. The carbon intensity of electrosynthesis products is primarily influenced by the significant energy requirements for conversion and product separation phases.

Summary: Carbon capture and utilization aims to mitigate climate change by delaying carbon emissions through temporary storage. A comprehensive Life Cycle Assessment (LCA) study on a novel process generating formate shows significant environmental trade-offs with conventional processes, indicating the need for high recycling rates and potential benefits from future negative CO2 market prices. Although results are conservative due to lab data, carbon utilization systems show promise in outperforming conventional methods in various impact categories.

Summary: To achieve the ambitious goal of carbon neutrality by 2050, it is necessary to significantly reduce carbon dioxide emissions from human activities. Traditional wet scrubbing carbon capture technology requires high energy consumption and extensive use of amine CO2 sorbents. Electrochemical direct carbon capture (EDCC) technology, on the other hand, offers the potential for capturing CO2 from diluted sources and achieving net-zero carbon emissions. Therefore, it is crucial to design cost-effective and energy-efficient CO2 adsorbent molecules for EDCC applications.

Summary: Reducing carbon dioxide emissions is crucial for sustainable development. A study on 12 AAILs revealed the dominant role of anions in CO2 absorption and the synergistic absorption by multiple-sites of amino and carboxyl groups in the anion.

Summary: In this study, a membrane-based system was developed to capture CO2 from dilute mixtures and convert it into value-added products continuously and under mild conditions. The quaternized poly-(4-vinylpyridine) (P4VP) membranes were found to be selective for CO2 separation and catalytically active for cyclic carbonate synthesis. The integration of CO2 capture and conversion in the catalytic membrane provides an energy-efficient alternative to traditional methods of capture, compression, transport, and storage. Furthermore, the membrane can potentially be tuned for the conversion of CO2 into various products, bringing a transformative shift in carbon capture and utilization technology.

Summary: Due to the lack of established procedures, we propose a simple method to estimate the LFL of arbitrary fuel-air mixtures based on a relationship introduced over 80 years ago. This method provides a constant fraction of the stoichiometric concentration of fuel as the LFL, except for halogen compounds. The element count on the fuel structure primarily determines the LFL values, which contrasts with the assumptions of quantitative structure-property relationship (QSPR) and group contribution (GC) approaches.

Summary: A small library of 1H-benzo[4,5]imidazo[1,2-c][1,3]oxazin-1-one derivatives was synthesized in good to excellent yields via a Ag2CO3/TFA-catalyzed intramolecular oxacyclization of N-Boc-2-alkynylbenzimidazole substrates. The regioselectivity of this process was high, as only 6-endo-dig cyclization was observed. The silver catalyzed 6-endo-dig cyclization of N-Boc-2-alkynylbenzimidazoles as substrates showed effectiveness and compatibility, providing a practical regioselective access to diverse 1H-benzo[4,5]imidazo[1,2-c][1,3]oxazin-1-ones in good yields.

Summary: Photocathodes with multiphasic Ag/AgBiW2O8/Bi2WO6 particles were synthesized and evaluated for light-assisted oxygen reduction reaction (ORR). The photocathode showed enhanced cathodic photocurrent and decreased impedance under irradiation. When combined with a photoanode and a solar cell, the photocathode enabled the production of H2O2 from ORR in a sustainable solar-driven photoreactor for water remediation.
