Abstract
In the present work, the preparation of nickel ferrite (NiFe2O4) and its surface
modification by biosynthesized Pd nanoparticles (NPs) were carried out. Firstly,
NiFe2O4 NPs were synthesized via a facile combustion approach and then Pd
NPs were biosynthesized on their surface by using an aqueous Marrubium
vulgare L leaf extract. The prepared NiFe2O4 NPs were characterized by FT-IR,
XRD, VSM, FESEM, and EDXA techniques, which confirmed the good dispersion
of spherical Pd NPs on the surface of magnetic NiFe2O4 nanoparticles. The
catalytic activity of Pd/NiFe2O4 nanocomposites were evaluated in the
reduction of Methylene Blue (MB), Methyl Orange (MO) and Congo Red
(CR) azo dyes in the presence of sodium borohydride (NaBH4). Observed
results showed that the reduction/decolorization times in the presence of
magnetically recoverable Pd/NiFe2O4 nanocomposites were very shorter than
that of NiFe2O4 catalyst.
