Abstract

Abstract: Current study deals with the generation of Sn based nanostructures with inherent magnetic character as efficient catalyst for the reductive transformation of nitroarenes to corresponding amines. In this context, Sn incorporated spinel nanoferrites- CoSnx Fe2−x O4 and NiSnx Fe2−x O4 ; x = 0.1, 0.2, 0.3 and 0.4 have been synthesized via most facile sol-gel methodology. The knowledge of successful incorporation of Sn in to the lattice of spinel nanoferrites (without the formation of any impurity), have been acquired from the shift in the band positions in the FT-IR spectra and shift in the peak positions observed in the powder X-ray diffraction patterns. The saturation magnetization has been found to decrease with successive Sn inclusion which confirmed the octahedral site preference of Sn. With the incorporation of Sn in to the lattice of CoFe2 O4 and NiFe2 O4 drastic improvement in the catalytic performance has been observed in comparison to undoped nanoferrites. Graphical abstract: Sn based nanomaterials have been established as very efficient, versatile, magnetically recoverable, recyclable and leach-proof catalytic systems with enhanced performance. fx1 Highlights: Sn based nanomaterials with inherent magnetic character via sol-gel methodology. Shift in FT-IR bands and XRD peaks confirmed the successful incorporation of Sn. Decrease in saturation magnetization confirmed the octahedral site occupancy of Sn. Drastic improvement in catalytic efficiency with Sn inclusion in to the lattice. Magnetically recyclable and leach-proof catalytic system has been developed.
