摘要 Development of efficient, green and recyclable?heterogeneous catalysts?for the chemical conversion of CO2?into cyclic carbonates with excellent yields under atmospheric pressure condition is still a very challenging task. Herein, a class of biomass-derived hyper-cross-linked porous heterogeneous catalysts MPAc-Br and MPAc-OH-Br, based on easily available and sustainable rosin, was synthesized by Friedel–Crafts polymerization and the further?N-alkylation of?triazole?groups. Compared with MPAc-Br, the?bifunctional catalyst?MPAc-OH-Br (bearing triazole?IL?groups and -OH groups) exhibited higher catalytic activity for direct chemical conversion of CO2?into cyclic carbonates (up to 99% yields) under metal-, solvent-free and atmospheric pressure conditions. The rosin-based porous molecular structure and bifunctional groups on the surface of MPAc-OH-Br played a very important role in the promoting the?cycloaddition?of CO2?with?epoxides?under the optimal conditions. Furthermore, MPAc-OH-Br exhibited good stability and reusability (96% yield after 10 recycles).
