Abstract
The formation of M@dendrimer composites (M = platinum, iridium) is reported, at room temperature, by mechanical milling of commercially available metallic precursors, sodium borohydride and small generation triazine-based dendrimers. After impurity removal, the composites are characterized by TEM showing spherical, worm-like or agglomerated nanoparticles depending upon the macromolecule stabilizer used. As a test of the surface activity of the metallic nanoparticles, the study of activity of the composites on the catalytic reduction of 4-nitrophenol show differences for each metal employed and suggest that surface of the NPs is not passivated by the presence of the stabilizer dendrimers.
