The Fe3O4 / Fe2O3 heteroplasmon hollow nanorod prepared by the method has the advantages of controllable process and controllable material morphology.

Description

technical field [0001] The invention relates to a magnetic Fe 3 o 4 / Fe 2 o 3 The invention relates to a heterogeneous hollow nanorod material and a preparation method thereof, which belong to the technical field of preparation of inorganic nonmetal nanocomposite materials. Background technique [0002] The development of human society is inseparable from the progress of material science. As people gradually study material science in depth, the demand for new materials is gradually increasing. At present, magnetic nanomaterials with excellent magnetic properties and small size effects have become a research hotspot, and more and more magnetic nanomaterials are widely used in the fields of machinery, electronics, optics, magnetism, chemistry and biology. However, the vast majority of magnetic nanomaterials contain heavy metals. Due to the biological toxicity of heavy metals and their harm to the environment, the application of magnetic nanomaterials in various fields is g...
