“…In 2022, Cheng's team [50] prepared six vinyl imidazole ion liquids with different functional groups and then copolymerized them with methyl methacrylate and ethylene glycol dimethyl acrylate to obtain imidazole‐based PILs named polymer ionic liquid materials (PILMs). CO 2 was converted into cyclic carbonate through gas‐liquid reaction and gas‐phase conversion process catalyzed by PILMs.…”

The reaction of carbon dioxide (CO2) with epoxide to generate cyclic carbonates is one of the most effective chemical fixation methods. The catalytic system significantly affects the carbon fixation efficiency of the reaction. Among the reported catalytic systems, porous materials as heterogeneous catalysts have attracted significant attention. This study aimed to summarize porous materials that catalyzed the conversion of CO2 into cyclic carbonates, including metal organic frameworks, covalent organic frameworks, poly(ionic) liquids, hyper crosslinked polymers, conjugated porous polymers and others. The study analyzed the catalytic properties of these materials and outlined future research directions.

“…To further study the physical cyclic reprocessing performance of ECMP, the ECMP-1.0 sample was pulverized and hot-pressed under 1 MPa at 160 °C for 80 min to obtain uniform and consistent films (Figure 5h). In addition, the FTIR (Figure S10) and 1 NMR (Figure S11) spectra of the recycled sample exhibit similar spectra to those of the original material, which verified that the structure of the material does not change after the physical cycle. After three cycles, the tensile strength of the material still recovers to 66% of its original strength (Figure 5i).…”

“…Over the past few decades, exponentially increased CO 2 in the atmosphere has become the main culprit for global warming and climate change. , As a sustainable resource of C1, CO 2 can be permanently stored as high value-added chemicals through biological, physical, and chemical conversion, , which can mitigate environmental issues and bring economic benefits simultaneously . The coupling reaction of CO 2 and epoxides to synthesize cyclic carbonates is one of the effective methods to achieve carbon sequestration.…”

Non-isocyanate polyurethanes (NIPUs) from renewable resources have attracted wide attention because of their remarkable benefits to sustainable development and green production. In this work, a strong, self-healing, and catalyst-free NIPU (ECMP) was prepared based on the hyperbranched biobased cyclic carbonate (Ec-MTDA) synthesized through catalytic carbonization of 1,8-menthane diamine (MTDA) and CO 2 . The hyperbranched and rigid structures of ECMP enable improved mechanical properties that a high tensile strength of up to 34.9 MPa can be achieved. Benefiting from the dynamic transesterification reaction between the carbamate and hydroxyl groups, ECMP presents favorable self-healing, reprocessing properties, and shape memory. Notably, 91% of the original tensile strength can be recovered after self-healing behavior. In addition, abundant polar groups provide excellent adhesion properties for ECMP with a high shear strength of 7.09 MPa. This study provides a promising strategy for the design of bio-based NIPUs, which broadens their applications in printing, furniture, packaging, and other industries.

“…In light of this, various metal-based ionic liquids (ILs) have been recently introduced in the literature, [ 50 , 51 , 52 , 53 ] showing good to excellent yields and selectivity, typically by the application of high CO 2 pressures (up to 50 bar). Additionally, ILs based on quaternary ammonium, imidazolium, and pyridinium salts, eventually immobilized on inorganic [ 54 ] and polymeric [ 55 ] solid supports, or prepared as hybrid materials, [ 56 ] have received considerable attention, showing advantageous features such as uninflammability, low volatility, thermal stability, and flexible structure-tailorability [ 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ]. In particular, it has been demonstrated that the presence of hydroxyl groups on the IL moiety significantly increases the catalyst activity as a result of the synergistic effect of hydrogen bonding with the oxygen atom of epoxides, which effectively contributes to the ring-opening process promoted by the halide nucleophilic attack ( Figure 1 ) [ 65 , 66 , 67 , 68 , 69 , 70 , 71 ].…”

Efficiency in Carbon Dioxide Fixation into Cyclic Carbonates: Operating Bifunctional Polyhydroxylated Pyridinium Organocatalysts in Segmented Flow Conditions

et al. 2023

Novel polyhydroxylated ammonium, imidazolium, and pyridinium salt organocatalysts were prepared through N-alkylation sequences using glycidol as the key precursor. The most active pyridinium iodide catalyst effectively promoted the carbonation of a set of terminal epoxides (80 to >95% yields) at a low catalyst loading (5 mol%), ambient pressure of CO2, and moderate temperature (75 °C) in batch operations, also demonstrating high recyclability and simple downstream separation from the reaction mixture. Moving from batch to segmented flow conditions with the operation of thermostated (75 °C) and pressurized (8.5 atm) home-made reactors significantly reduced the process time (from hours to seconds), increasing the process productivity up to 20.1 mmol(product) h−1 mmol(cat)−1, a value ~17 times higher than that in batch mode.
