摘要：
A facile and environment-friendly sonochemical route to fabricate well-defined Fe(3)O(4)/Pt and gamma-Fe(2)O(3)/Pt composite microspheres under mild conditions has been reported. The structure and morphology of the synthetic spherical-shaped Fe(3)O(4)/Pt and gamma-Fe(2)O(3)/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 (fcc) 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.
