摘 要: | 通过一步吸附法直接将烯烃复分解反应第二代Hoveyda-Grubbs催化剂固载到磁性多孔复合材料(Fe3O4@mSiO2)上,制备出可磁性分离的固体催化剂。该催化剂在烯烃复分解反应中表现出较高的活性和循环性能,催化循环使用5次后,仍能保持新鲜催化剂的活性。该催化剂不仅制备方法简单,且可通过外加磁场的方法实现快速、高效分离回收。 |
关 键 词: | 物理化学;磁性;多孔;烯烃复分解反应;固体催化剂;循环 |

Abstract: | A new solid catalyst for olefin metathesis was developed through direct adsorption of the second generation Hoveyda-Grubbs catalyst on the magnetic porous composite (Fe3O4@mSiO2). The solid catalyst showed a high activity and excellent recyclability in olefin metathesis. After 5 recycles, this catalyst still maintained the activity of fresh catalyst. Impressively, the preparation of this catalyst was simple, and it could be effectively separated and recovered through a magnetic field. |
