Zn(II)-Embedded Nanoporous Covalent Organic Frameworks for Catalytic Conversion of CO₂ under Solvent-Free Conditions

ACS Applied Nano Materials, Год журнала: 2021, Номер 4(8), С. 7663 - 7674

Опубликована: Июль 28, 2021

Covalent organic frameworks (COFs) have been gaining substantial attention over the past decade due to their developing crystalline porous polymeric nature linked by strong covalent bonds and widespread applications in various fields. Currently, three-dimensional COFs (3D COFs) are engaging spotlight distinctive features, greater surface area, exceptional performances comparison with formerly published two-dimensional (2D) AA-stacking layered mode. In this paper, we present, for first time, a nanoporous 3D-COF-based zinc(II) catalyst (Zn@RIO-1), which shows an efficient pathway chemical conversion of carbon dioxide produce α-alkylidene cyclic carbonates oxazolidinones from propargylic alcohols. The microporous material high area (312.61 m2/g) facilitates both types catalytic reactions under atmospheric CO2 pressure. More importantly, easily recyclable reusable catalysts produced moderate yields desired as well oxazolidinone products solvent-free conditions. This study emphasizes capability catalysis field, more specifically field capture fixation fine chemicals. These results pave spectacular into alcohols using 3D-COF potential heterogeneous ligand sustainable conditions (i.e., solvent-free).
