Abstract: The spindle-shaped core-shell Fe2O3@CuO nanoparticles were prepared by one step homogeneous precipitation method using Fe (NO3)3,Cu(NO3)2 and urea as precursor materials.The morphology,elemental composition and phase composition of samples in different synthesis stages and conditions were characterized by transmission electron microscope (TEM),energy dispersive spectroscopy (EDS) and powder X-ray diffraction (XRD).The results indicated that Fe3+ and Cu2+ were firstly precipitated respectively,then Cu deposition were dissolved and transformed into Cu (OH)2 nano sheets,which finally aggregated onto the core α-Fe2O3 particles and formed the spindle-shaped core-shell nanoparticles.
