| titleOfInvention | Amorphous core-shell structure nanoparticle and preparation method thereof |
| abstract | The invention discloses an amorphous core-shell structure nanomaterial and a preparation method thereof. The amorphous core-shell structure nanomaterial takes magnetic metal nanoparticles as a core, and takes a metal oxide as a shell. The preparation method, i.e., a chemical reduction method, comprises the following steps of: 1. preparing a salt-containing aqueous solution in which a polymer dispersant agent is dispersed; 2. preparing a reducing agent solution; 3. placing the prepared reaction solution in a microfluid reaction system to react and collecting a product; and 4: washing and separating to obtain the amorphous core-shell structure nanoparticles. The amorphous core-shell structure nanoparticles with uniform and dense shell layers can be obtained by one step by the preparation method provided by the invention, the further oxidation of the core can be effectively prevented by the shell layers, the stability of the material is improved, and the preparation method is simple. |
