摘要：

Fe2O3@SiO2@Ag composites were synthesized, using the coprecipitation method to obtain maghemite nanoparticles coated with SiO2 using the Stober method to avoid the oxidation, and finally silver nanoparticles were incorporated by a chemical method. The samples were characterized by X-ray diffraction, transmission electron microscopy, IR spectroscopy and vibrating sample magnetometry.
