| 摘 要： | Fe3O4纳米微粒是一种制备磁性液体的重要组成部分。但Fe3O4纳米微粒不稳定,极易氧化成γ-Fe2O3,其磁化强度也会明显降低1-2]。铁氧体还易为酸溶解,化学反应式为:MFe2O4 8H M2 2Fe3 4H2O式中M为Fe、Co、Mn等二价金属。在Massart法制备酸性离子型磁性液体的方法中,采用了Fe(NO

| Abstract: | Fe_3O_4 nanoparticles,prepared by coprecipitation and treated with Fe(NO_3)_3,were analyzed by vibrating sample magnetometer,transmission electron microscope,X-ray diffraction instrument and X-ray photoelectron energy spectrometer.The results showed that a fine N-O-Fe layer was formed on the surface of the treated Fe_3O_4 nanoparticles.The surface layer is non-magnetics,resistant to oxidation and acid.The binding energies are E(Nls)=406.65 eV,E(Ols)=532.93 eV and E(Fe2P_(3/2))=710.09 eV,respectively. |
