Abstract

Abstract: CuO, Fe3 O4 and CuFe2 O4 /CuO over montmorillonite (MMT) clay were prepared with an eco‐friendly manner utilizing aqueous fruit extracts of the Terminalia chebula ( T. chebula ). FT‐IR and EDS spectra, XRD patterns and FE‐SEM images revealed the growth of nanoparticles on the layers of montmorillonite clay. The catalytic activity of as‐prepared nanocomposites was comparatively evaluated in the synthesis of aminotetrazole derivatives and resulted in the order of CuFe2 O4 /CuO/MMT>CuO/MMT>Fe3 O4 /MMT in their activity for the regioselective synthesis of aminotetrazoles. The combination of the acidic character of MMT clay along with the synergistic electronic effect between nanoparticles result in the superior catalytic activity of CuFe2 O4 /CuO/MMT which showcased the enormous potential of metallic supported nanocomposites in the catalysis field. The magnetic CuFe2 O4 /CuO/MMT nanocomposite was successfully reused and recovered for several times without consequential abate. Abstract : We comparatively investigate the catalytic activity of green synthesized CuO, Fe3 O4, and CuFe2 O4 /CuO over montmorillonite (MMT) in the synthesis of aminotetrazole derivatives. Concisely, we demonstrate the order of CuFe2 O4 /CuO/MMT>CuO/MMT>Fe3 O4 /MMT in their activity for the regioselective synthesis of aminotetrazoles, which can be reasoned by the combination of the acidic character of MMT clay along with the synergistic electronic effect between nanoparticles.
