Fe₃O₄@SiO₂@CSH⁺VO₃^- as a novel recyclable heterogeneous catalyst with core-shell structure for oxidation of sulfides.

ABSTRACT: Iron nanoparticles, with low toxicity and many active sites, are among the materials that not only reduce waste along with green chemistry but also increase the separation power and recover the catalyst from the reaction environment. In this study, first, the surface of iron nanoparticles was silanized, and in the next step, the complex of chitosan HCl.VO₃ was placed on the surface of Fe₃O₄ (Fe₃O₄@SiO₂@CSH⁺VO₃^-). This nanocatalyst is a novel, recoverable, and potent nanocatalyst with high selectivity for the oxidation of sulfides to sulfoxides. Various physicochemical techniques such as IR, XRD, TGA, SEM, EDX, mapping, TEM, and VSM were used to affirm the well synthesis of the catalyst. Oxida
