Patent number: 11980875Abstract: A method for making a magnetic-nanoparticle-supported catalyst includes reacting a ferrocenyl phosphine compound with an amino alcohol compound to form a ligand having a phosphine group, an amine group and at least one hydroxyl group; anchoring the ligand to a surface of magnetic nanoparticles via an oxygen atom of the hydroxyl group to form a ligand complex; combining the ligand complex with a metal precursor comprising Rh to bind the metal precursor with the ligand complex and form the magnetic-particle-supported catalyst. The magnetic-particle-supported catalyst is a Rh complex of magnetic-Fe3O4-nanoparticle-supported ferrocenyl phosphine catalyst.Type: GrantFiled: August 23, 2022Date of Patent: May 14, 2024Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: M.
