The carbon dioxide (CO2) capture and utilization strategy has emerged as an innovative multifaceted approach to counteract emissions. In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; H3TATB = 4,4',4″-s-triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites basic nitrogen-rich triazines. BaTATB demonstrated selective CO2 adsorption high heat of adsorption. Its abundance (Ba clusters) (triazine) makes ideal catalyst for the cycloaddition epoxides in two- three-component reactions. Furthermore, is exceptional recyclable aromatic amines, enabling high-yield synthesis cyclic carbonates oxazolidinone at 1 bar under moderate, solvent-free, cocatalyst-free conditions. Additionally, recycled nine seven consecutive cycles carbonate no substantial decrease catalytic activity. Using density functional theory, we rational design metal-organic frameworks that exhibit excellent conversion.

Though polyurethanes (PUs) are widely used in people’s daily lives, traditional PUs generally fabricated from toxic (poly)isocyanates. Furthermore, (poly)isocyanates commonly industrially prepared a seriously and injurious chemical compound named phosgene, which is dangerous gas that can cause lung irritation eventually death. As known to all, the consumption of carbon dioxide (CO2)-based raw materials reactions productions will be conducive reducing greenhouse effect. In this paper, non-isocyanate polyurethane (NIPU) diol was through polyaddition reaction ethylenediamine CO2-based ethylene carbonate, then NIPU-based silicone-containing thiol hyperbranched polymers (NIPU-SiHPs) were synthesized NIPU diol. Finally, UV-curable optical-silicone-modified coatings (UV-NIPUs) NIPU-SiHPs pentaerythritol triacrylate by UV-initiated thiol-ene click without UV initiator. The UV-NIPUs demonstrated high transparency over 90% (400–800 nm), good mechanical performance with tensile strength reaching 3.49 MPa, superior thermal stability an initial decomposition temperature (Td5) range 239.7–265.6 °C, moderate hydrophilicity water contact angle 42.6–62.1°, pencil hardness 5–9H, adhesive grade 0. results indicate it promising green strategy fabricate high-performance materials.

Carbon dioxide (CO 2 ) reduction through chemical fixation has attracted great attention due to its key role in climate change. The conversion of CO the five-membered cyclic carbonates is most practical and invaluable process, particularly when using sustainable green methodologies. Two amine-tethered 4-dimethylamino pyridine ionic organocatalysts were prepared two different solvents a simple cost-effective procedure. mole ratio solvent effect on structure investigated. Then, was investigated by reaction with epoxides presence as-prepared under solvent-free conditions. Moreover, influence organocatalyst structures conditions cycloaddition studied find high efficiency valuable carbonates. optimized 80°C 0.2 MPa give good excellent yields selectivity. Given recyclability organocatalyst, current catalytic can be promising scale-up process.

Polyhydroxyurethanes (PHUs) synthesized from cyclic carbonates are promising alternatives to conventional polyurethanes due their advantageous isocyanate-free synthesis and reprocessability characteristics. While many studies focus on PHUs derived five-membered (5CCs) for more sustainable routes, six-membered (6CCs) exhibit enhanced reactivity towards amines. Their is facilitated by the presence of hydroxyl groups along polymer chain, enabling transcarbamoylation reactions. However, since non-catalyzed typically a sluggish reaction, catalysts often required enhance network reprocessability. This study presents life cycle assessment (LCA) PHU-5CC PHU-6CC syntheses, with catalysts, recycling applications targeting end-of-life scenarios. Environmental impact categories, including climate change, particulate matter, fossil resource depletion, mineral metal use freshwater eutrophication, were evaluated. Sensitivity analyses also conducted assess key variables. Our results indicate that 6CCs show higher environmental footprint solvent-intensive process. Despite increased shorter reaction times associated 6CC monomer, these benefits do not fully offset impacts In conclusion, this highlights potential improvements future PHU synthesis, such as solvent-free processes, metal-free optimized monitoring.
