摘要 本文主要分析了超顺磁性Fe3O4@SiO2纳米复合粒子的化学制备方法,并简要分析了其作为催化载体在催化剂分离方面的应用前景。通过各种制备方法的比较,认为经由稳定的磁性Fe3O4液体(或称Fe3O4磁流体)是制备均匀包覆的Fe3O4@SiO2样品的比较理想的路线。 This review focuses on the preparation of superparamagnetic Fe3O4 @ SiO2 nanoparticles and its application in catalyst separation. A desired synthesis route can be summarized by comparing the effect of different preparation methods on the morphology and properties of the formed samples.
