Polymeric and Crystalline Materials for Effective and Sustainable CO2 Capture

AppliedChem, Journal Year: 2024, Volume and Issue: 4(3), P. 236 - 269

Published: June 26, 2024

Carbon dioxide (CO2) is recognized as the primary cause of global warming due to its greenhouse potential. It plays a significant role in contributing emissions arising from variety anthropogenic activities, such energy production, transportation, construction industry, and other industrial processes. Capturing utilizing CO2 mitigate impact on environment is, therefore, importance. To do so, strategies net-zero strategies, deploying capture storage technologies, converting into useful products have been proposed. In this review, we focused our attention preparation performance polymeric crystalline materials for efficient capture. More precisely, examined MOFs, petroleum-based polymers (amine-based, ionic liquid, polymer, conjugated macro/micro-cyclic porous organic polymer) well bio-based brief, present work aims guide reader available crafted offering promising avenue towards innovative carbon strategy.

Construction of Polymers with Highly Dispersed Reactive Phases and Open Pores for Catalyzing the Efficient Synthesis of CO₂ to α‐Methylene Cyclic Carbonates

Asian Journal of Organic Chemistry, Journal Year: 2024, Volume and Issue: 13(7)

Abstract Selective capture of carbon dioxide as a C1 feedstock for the preparation high‐value chemicals has been recognised an important way to mitigate crisis. In this work, new heterogeneous catalyst, Cu@CP‐PII, was developed through rational construction open‐pore organic skeleton, which is easy synthesise and highly efficient. With synergistic effect between high CO 2 affinity porous skeleton dispersed Cu(I) sites activated alkynes, it can be used efficient α‐methylene cyclic carbonates at ambient temperature pressure. The structure morphology were exhaustively characterised by Solid State 13 C‐NMR, FT‐IR, XPS, TEM N adsorption‐desorption tests, catalyst possessed surface area 273.7 m ⋅ g −1 uniformly dispersion CuI. To test its catalytic activity, Cu@CP‐PII in amount only 0.4 mol% carboxylative cyclization reaction propargylic alcohols with , resulted substrate conversions up 100 % yields greater than 99 %. addition, controlled experiments mechanistic elucidation confirmed that anhydrous low temperatures are necessary achieve selective control target product carbonates.
