Preparation and characterization of nanofibrous metal–organic frameworks as efficient catalysts for the synthesis of cyclic carbonates in solvent-free conditions

Abstract

Environmental concerns particularly global warming represent serious threats to public health globally. Metal−organic frameworks (MOFs) are innovative materials with prominent features such as ultrahigh surface area, high porosity and tunable...

Guanidyl-implanted UiO-66 as an efficient catalyst for the enhanced conversion of carbon dioxide into cyclic carbonates

“…However, the ECH conversion yields decreased with the increasing amount of the catalyst, possibly owing to the limited mass transfer in the porous structure of the catalyst. 37 Moreover, the significantly enhanced CPC yield could be observed with the increasing percentage of TBAB from 0.4 to 0.8 mol% (Fig. 4b), whereas the increasing yield was slowed down (2%) when the content of TBAB was further increased to 1.0 mol%.…”

Integration of polypyridyl-based ionic liquids into MIL-101 for promoting CO2 conversion into cyclic carbonates under cocatalyst-free and solventless conditions

“…3(a)), but with a further increase in the MIL-101-IL(BuBr) catalyst dosage (120 mg), the yield slightly decreased to 89% due to the limited mass transfer in the pores. 40 When the reaction temperature was raised from 80 °C to 110 °C (Fig. 3(b)), greater catalytic performance of MIL-101-IL(BuBr) was observed under 1.0 MPa CO 2 for 6 h. The impact of CO 2 pressure on CO 2 cycloaddition with ECH is also investigated (Fig.…”

Carbonic Anhydrase-Embedded ZIF-8 Electrospun PVA Fibers as an Excellent Biocatalyst Candidate

“…Running as crystal seeds, these nanocomposites (enzyme-embedded MOFs) were in situ grown on the electrospun polyvinyl alcohol fibers. Anchoring of enzyme-embedded MOFs on the surface of the electrospun polyvinyl alcohol fibers increases the enzyme’s stability, prevents its leaching, and guides the scientists to use fibrous composites with simple separation and excellent reusability . Notably, the biocatalytic composites showed an excellent CO 2 capture capacity compared to the conventional BCA@ZIF-8 and free BCA.…”
