摘　　要：Synthesis of cyclic carbonates from carbon dioxide(CO_(2))and epoxides is an effective pathway for the CO_(2) 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 CO_(2) 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 CO_(2) pressure.In addition,Mo@SBA-15 was reused seven times without any significant activity loss.由二氧化碳(CO_(2))和环氧化物合成环状碳酸酯是CO_(2)利用的有效途径.尽管各类金属催化剂相继见诸报道,但依然急需开发一类可回收或再循环的催化剂.该工作将SBA-15负载的N-杂环卡宾-吡啶钼络合物(Mo@SBA-15)作为一类高效和可循环利用的催化剂应用于CO_(2)和环氧化物合成环状碳酸酯.Mo@SBA-15与四丁基溴化铵(TBAB)组成的双组分催化体系在100℃和CO_(2)(1 MPa)压力下合成环状碳酸酯时,显示出了较高的催化活性.此外,Mo@SBA-15重复使用7次未发现明显的活性降低.
