In this study, an efficient, reusable, and environmental catalytic system consisting of sugarcane bagasse (an agricultural and sugar mill waste material, SCB) and KI was applied to the cydoaddition of carbon dioxide (CO2) to epoxides or aziridines under mild conditions for the first correlated with the large quantities hydroxyl groups in SCB, which had a time. Their catalytic cycloaddition activities were found to be well synergetic effect with the halide anion of KI. The as-prepared catalytic system also exhibited excellent cycloaddition activities for various epoxide or aziridine substrates as well. Moreover, the catalyst could be recovered and reused multiple times without obvious loss in activity. The present method represents an integrated and ideal green process for the utilization of biomass and carbon neutral resources, which has a high potential for large-scale fixation of CO2 into value-added chemicals.
