The transformation of carbon dioxide (CO2) into functional materials has garnered considerable worldwide interest. Metal–organic frameworks (MOFs), as a distinctive class materials, have made great contributions to CO2 capture and conversion. However, facile conversion stable porous MOFs for utilization remains unexplored. Herein, we present methodology using synthesize zirconium-based MOFs. Two CO2–Zr-DEP CO2–Zr-DEDP with face-centered cubic topology were obtained via sequential desilylation–carboxylation–coordination reaction. exhibit excellent crystallinity, verified through powder X-ray diffraction high-resolution transmission electron microscopy analyses. They also notable porosity high surface area (SBET up 3688 m2 g–1) good adsorption capacity (up 12.5 wt %). resulting abundant alkyne moieties, confirmed 13C cross-polarization/magic angle spinning nuclear magnetic resonance Fourier transform infrared spectra. Leveraging the catalytic prowess Ag(I) in diverse CO2-involved reactions, incorporated MOFs, capitalizing on their interactions carbon–carbon π-bonds alkynes, thereby forming heterogeneous catalyst. This catalyst demonstrates outstanding efficiency catalyzing propargylic alcohols cyclic carbonates, achieving >99% yield at room temperature atmospheric pressure conditions. Thus, this work provides dual strategy, encompassing synthesis CO2-based (20–24 % from CO2) subsequent application processes. approach significantly enhances overall utilization.

To address the CO2 accumulation in atmosphere, various initiatives have been proposed, among which capture and utilization (CCU) is regarded as an appealing strategy to reconcile carbon emission resource utilization. Especially, integrated (ICCU), i.e. performing in-situ conversion can circumvent energy-intensive desorption step thus facilitate establishing step- energy-efficient process, rendering at mild conditions particularly low pressure due substantial activation upon uptake. However, not simple add-up of these two processes. Its successful implementation relies on harmonization reagents, substrates corresponding catalysts. By far, tremendous efforts made this field a plethora reagents including inorganic bases, organic ionic liquids carbonaceous materials utilized protocols such hydrogenation, cycloaddition, carboxylative cyclization etc. explored for captured CO2. As result, valuable products containing methanol, methane, carbonates, carbamates, oxazolidinones, ureas, quinazolinone obtained from more importantly, chemistry theory also enriched via investigating structure reactivity reactions. In review, we summarize progress based reaction types absorbents. It's hoped that review shed light design inspire further development field.

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.
