| 摘 要： | 以二价铁盐为原料,利用环氧化物的胶凝或沉淀作用,以乙醇或水作为反应介质,在较低的温度下制备Fe3O4纳米粒子.表征结果表明,以H2O为溶剂可得到粒径在25～83 nm之间粒度分布较宽的Fe3O4纳米颗粒,而以乙醇为介质时,可得到粒度分布窄近单分散Fe3O4纳米粒子.由于该路线在制备纳米氧化物方面具有反应条件温和、工艺简单、原料价廉和易于规模化制备等优点,显示出其具有工业化前景.

| Abstract: | Herein,ferrous iron salt is used as precursor to prepare Fe3O4 nanoparticles in aqueous or ethanolic solutions at low temperature through epoxide gelation or precipitation process.Characterization results show that the size of Fe3O4 nanoparticles synthesized in aqueous solution is around 25-83 nm with wide particle size distribution.On the other hand,in ethanolic solution,nearly monodispersed Fe3O4 nanoparticles can be obtained.Due to advantages of mild reaction conditions,facile process,cheap raw materials... |
