摘要
Tannic acid （TA）/KI as a cheap,green,highly-efficient,biocompatible,and recyclable catalytic system represents the excellent synergistic effect in the cycloaddition reactions of CO2 and epoxides under solvent-free conditions,which is originated from hydrogen bonding between the hydrogen atoms of phenolic hydroxyl groups within TA and the oxygen atom of the epoxide.Therefore,it is considerable to be a sustainable methodology for the utilization of bio-resources.
