Synthesis of cyclic carbonates from carbon dioxide (CO2) and epoxides is an effective pathway for the CO2 utilization. Although various metal catalysts have been reported, it is highly desirable to develop a method for the reuse or recycling of catalysts. Herein, an N-heterocyclic carbene-pyridine molybdenum complex supported over SBA-15 (Mo@SBA- 15) was used as an efficient and recyclable catalyst for converting CO2 and epoxides into cyclic carbonates. Mo@SBA-15 in combination with tetra-butylammonium bromide (TBAB) shows high catalytic activity in the synthesis of cyclic carbonates under 100 ℃ and 1 MPa CO2 pressure. In addition, Mo@SBA-15 was reused seven times without any significant activity loss.
