Optimization and kinetics of crown ether-based hydroxyl-rich organic polymers for sustainable CO2 fixation and iodine vapor adsorption

“…17,18 While the high free energy of epoxides can counterbalance the high thermal stability of CO 2 in the atmosphere, certain catalysts make the fixation of CO 2 onto epoxides thermodynamically advantageous. The current state of the art involves the development of a wide range of catalysts such as ionic liquids (ILs), 19–21 metal complexes, 22–27 metal organic frameworks (MOFs), 28–32 supported catalysts, 33–37 covalent organic frameworks (COFs), 38–40 and porous organic polymers (POPs), 41–47 each possessing distinct structures and functions, to efficiently facilitate this reaction. Among these, POPs exhibit unique CO 2 conversion and I 2 capture properties, due to their high intrinsic specific surface area, controllable pore size, synthetic versatility, exceptional physicochemical stability, and facile functionalization for creating metal-active centers.…”
