Features

We found an effective catalyst system composed of CeO2 and 2-cyanopyridine for direct and catalytic polycarbonate formation reaction from CO2 and diols. CeO2 acted as an activator for CO2 and diols, and 2-cyanopyridine shifted the equilibrium in favor of the product side by hydration of 2-cyanopyridine, promoting the reaction. Green polycarbonates can be synthesized by combination of the catalyst system with a technique of diol syntheses from biomass.

Targeted Application(s)/Industry

This catalyst system is effective for direct transformation of CO2, contributing to the effective utilization and emission reduction of CO2. Combination of the catalyst system with a concentration technique of CO2 will bring about much advantage.
