چکیده
|
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.
