Dysprosium (III) Supported on CoFe2O4 MNPs as a Heterogeneous Catalyst for the Selective Oxidation of Sulfides and Synthesis of Symmetrical Disulfides

Abstract

A magnetic catalyst based on immobilization of dysprosium ions on the surface of CoFe2O4 nanoparticles has been reported and used as an efficient magnetic nanocatalyst for the selective oxidation of organic sulfides and synthesis of symmetrical disulfides containing aromatic and aliphatic sulfides and thiols. The magnetic solid catalyst has been identified using TGA, FT-IR, VSM, ICP, SEM, and XRD. Moreover, the catalyst can also be separated with an external magnet and recycled several times without any remarkable decrease in its catalyst activity.
