摘要:
The cycloaddition of CO2 with epoxides to cyclic organic carbonates using metal-free heterogeneous catalysts is considered as a 100% atom-economic and environmental-friendly route for CO2 utilization. Herein, we developed a metal-free microporous polymeric spheres catalyst (p-TBIB) by a simple Friedel-Crafts alkylation and applied in the cycloaddition of CO2 to cyclic organic carbonates. The catalyst shows high CO2 uptake (62.7 cm(3) g(-1), at 298 K and 1 bar), high selectivity over N-2 (46 at 298 K) and perfect cycloaddition activities (66-97%) and selectivities (over 99%) and reusability (at least ten cycles) at ambient conditions (at 298 K and 1 bar).
