Abstract

A new magnetic nanocatalyst has been prepared using immobilization of vanadate onto aminopropyl functionalized SiO₂/Fe₃O₄(VO₃^-/NH₃⁺-SiO₂/Fe₃O₄). The obtained magnetic catalyst was characterized by FT-IR, XRD, VSM and SEM techniques and used for sulfoxidation of sulfide compounds to the correspondingsulfoxides in presence of H₂O₂ as oxidant at room temperature. The optimum of reaction conditions and reusability of catalyst have been investigated.
