Lignin‐Based Green Catalyst for the Chemical Fixation of Carbon Dioxide with Epoxides To Form Cyclic Carbonates under Solvent‐Free Conditions

Abstract

Fixated on CO2: Lignin, the second most-abundant biorenewable polymer on our planet, was successfully used as a catalyst in the presence of KI in the cycloaddition of CO2 with a series of epoxides. This method represents an integrated and ideal green process for the utilization of “carbon-neutral” resources.
