| Abstract: | The Fe3O4 magnetite nano-particles with average particle size of about 6.0 nm were prepared with polyol reduction method.Then the magnetite nanoparticles were acidized with hydrochloric acid solution(1 mol/L).Finally,Fe3O4@SiO2 composite nanoparticles were synthesized in OP-10/n-butanol/cyclohexane/ammonia reverse micro-emulsion system.The composite nanoparticles were characterized with X-ray powder diffraction(XRD),transmission electron microscopy(TEM),Fourier transform infrared spectroscopy(FT-IR),and vib... |
