摘要

Abstract

Recently

cyclic (alkyl)(amino)carbenes (CAACs) have been widely used as ligands to enhance the catalytic reactivity of center metal

but the problem of recycling this expensive ligand remains to be solved. In this work

the heterogeneous SBA-15-CAAC-Ir catalyst was prepared by a covalent attachment method

and using SBA-15 as the carrier. It shows high reactivity for the hydrogenation of CO

to formate. After immobilization

the ordered mesoporous structure and the overall rod-like morphology of the original SBA-15 have been preserved very well. Using SBA-15-CAAC-Ir as catalyst

up to 21050 TON can be obtained at 60 ℃. In addition

the catalyst can be separated easily by centrifugation

and the catalytic activity of SBA-15-CAAC-Ir can still remain very high after multiple cycles.
