Gd (III) and Tb (III) immobilized tryptophan functionalized magnetic nanoparticles for eco-friendly oxidation rections

In this study, Gd (III) and Td (III) immobilized magnetic nanocatalysts were prepared following a simple procedure using available materials. These nanoparticles were characterized by FT-IR, XRD, TGA, EDX, and ICP-OES studies and utilized in the S-oxidation reactions. It was observed that the rate of oxidation with Tb magnetic nanocatalyst was higher than that of Gd. Significant advantages of this environmental friendly process include short reaction times, high efficiency, and convenient recovery and reusability of the catalyst for several times without any significant loss of activity.
