Abstract:
The conversion of CO2 to useful chemicals,
especially to atom economical products, is the best approach
to utilize an excess of CO2 present in the atmosphere. In this
study, a metal-organic framework (ZIF-8) is integrated with
nanocrystalline zirconosilicate zeolite to develop an integrated porous catalyst for CO2 insertion reactions. The
catalyst exhibits excellent activity for the CO2 insertion
reaction of epoxide to produce cyclic carbonate in neat
condition without the addition of any co-catalyst. The catalyst
is stable and recyclable during the cyclic carbonate synthesis.
Further, the catalyst also exhibits very good activity in
another CO2 insertion reaction to produce quinazoline-2,4(1H,
3H)-dione.
