Effects of Metal Centers on CO2 Cycloaddition in MOFs
The use of simple reactions to immobilise CO2 under relatively mild reaction conditions to form high value-added products is a current scientific and technological challenge of great interest,where the cycloaddition of propylene oxide and CO2 is an ideal way to achieve carbon neutrality and immobilise CO2.The effective activation of CO2 is a prerequisite for this reaction.However,there are still open questions regarding the experimental reaction process and mechanism.Therefore,in this study,we prepare metal-organic frameworks(MOFs)materials with different metal centers for the addition reaction of CO2 with propylene oxide.The experimental results show that UiO-66-NH2 has the best catalytic effect.This study provides some new ideas for the design and application of CO2 cycloaddition reactions with different materials.
