Platinum Immobilization on Iron Oxide Nanoparticles Surface under Sonication

摘要：

A facile and environment-friendly sonochemical route to fabricate well-defined Fe3O4/Pt and y-Fe2O3/Pt composite microspheres under mild conditions has been reported. The structure and morphology of the synthetic spherical-shaped Fe3(VPt and Y-Fe2O3/Pt products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) with selected area electron diffraction (SAED). The results revealed that the composites were spherical with diameter in the range of 50-80 nm and had an ordered face-centered cubic (fee) structure of platinum. These nanocomposites with platinum-coated iron oxide can be applied in a variety of areas,including medicine,photonics,new functional device assemblies and catalysis especially for fabricating some magnetic-responsive catalyst.
