Advance in preparation of Fe3O4 nanoparticles by solvothermal method
摘要
Abstract
Fe3 O4 is an excellent functional material widely applied to water purification,magnetic fluid,targeted drugs,etc. due to excellent magnetic property and high chemical stability. The main synthetic methods include coprecipitation, thermal decomposition, micro-emulsion and solvothermal method. The solvothermal method,benefiting from diverse products varying in shapes and appearances,high regularity and simple procedures,gains the most popularity. The solvent,mineralizer and surfactant applied in this method have relatively great impact on the shape,appearance and performance of Fe3 O4 nano particle. In such context,in the paper,the preparation procedures of Fe3 O4 nano particle by use of the solvothermal method has been described,based on which the mechanism for synthesis of hollow Fe3 O4 nano particle by the solvothermal method has also been expounded. In conclusion,the solvent serves as the reductive agent while providing necessary liquid-phase environment for the synthesis;the mineralizer facilitates the dissolution of iron precursor thus ensuring the smooth proceeding of the synthetic reaction;the shapes and appearances of Fe3 O4 nano particle vary with the types,concentrations of the surfactants,and acting Fe3 O4 crystal faces. In the end,the author has looked to the development trend of the synthesis of Fe3 O4 nano particle by use of the solvothermal method. On the basis of hollow Fe3 O4 ,the researcher's focus is on how to synthesize multilayered crustiform Fe3 O4 nano particle by use of high-viscosity solvent and surfactant.关键词
