A novel Fe3O4@VO (salen) complex was designed as an efficient and
heterogeneous catalyst for selective oxidation of sulfides to sulfoxides using H2O2 at
room temperature. The catalyst was characterized by techniques such as transmission
electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction
(XRD) analysis, Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric
analysis (TGA), vibrating-sample magnetometry (VSM), and inductively coupled
plasma optical emission spectrometry (ICP-OES) analysis. The simple preparation of
the catalyst from commercially available materials, excellent chemoselectivity, easy
separation of products, and straightforward recovery and reusability of the catalyst
with unaltered activity make our procedure a green and practical method.
