A new concept of tethered ligand-modified Rh/SiO2 catalyst for hydroformylation with high stability

---

Abstract
A tethered ligand-modified Rh/SiO2 catalyst was developed for hydroformylation with high stability. The
catalyst was prepared by fastening both organic ligand and metal directly on the surface of support to
avoid leaching, while at the same time the active species were formed in situ by coordination of the
flexible ligand to the metal on the surface of SiO2. The immobilization of ligand on SiO2 and the
interaction between ligand and metal were investigated by means of TG, solid-state NMR and FTIR.
Hydroformylation of ethylene was selected as a probe reaction to evaluate the immobilization and
coordination of ligand to the nano-metal particles. High activity and excellent stability were observed
during a 1000-h run.

Keywords: Tethered ligand, Rh/SiO2 catalyst, Hydroformylation
