Composite Fe3O4-SnO2 nanoparticles were synthesized by growing SnO2 nanoparticles on the surface of previously prepared Fe3O4 nanoparticles. First, Fe3O4 nanoparticles were prepared by chemical precipitation of precursors followed by the obtaining of SnO2 nanoparticles by chemical precipitation or sol-gel process. The composite nanoparticle samples were characterized by using X-Ray diffraction (XRD), Transmission Electron Microscopy (TEM) and X-Ray photoelectron Spectroscopy (XPS) techniques.
