Summary: A series of polymers were synthesized by copolymerization of vinyl functionalized polyhedral oligomeric silsesquioxanes (POSS) with vinylimidazole based linker, by adjusting the molar ratio of the two monomers. These POSS-based polymers were found to be efficient catalysts for the cycloaddition reaction of CO2 with various epoxides, producing cyclic carbonates with a high conversion of up to 97.1% under atmospheric pressure without solvent and co-catalyst. Moreover, the synthesized polymers significantly reduced the activation energy of the cycloaddition reaction of CO2 and could be recycled up to 5 times without a decrease in catalytic performance.

Summary: In this study, various layered double hydroxides (LDHs) and layered double oxides (LDOs) were synthesized by the co-precipitation method and evaluated as catalysts for ethylene glycol (EG) synthesis. Zn3Al-LDO exhibited the highest catalytic activity under low H2O/EC ratio and mild conditions, achieving an EG yield of 93%-99% at 100 degrees C for 3-4 h. The superior performance of Zn3Al-LDO is attributed to the absence of the memory effect and the retention of a significant number of base sites in the hydrolysis system. Catalyst recycling experiments showed that Zn3Al-LDO can maintain excellent catalytic activity after at least five cycles of calcination and activation.
