Abstract:
We prepared Fe3O4 magnetic nanoparticles with core size of 10nm by water co-precipitation.Then we obtained the Fe3O4/Ag nanoparticles with core-shell structure by reducing Ag[(NH3)2]+ with gallic acid as reducer and surface modifier.On the preparation conditions study,the ratio of materials,pH of the solution,crystallization temperature and the amount of sliver nitrate which contributed to the Fe3O4 nanoparticles have been discussed.
