摘要：
Controlled oxidation of amorphous core-shell Fe-Fe3O4 nanoparticles in a simple solution-phase process affords monodisperse hollow Fe3O4 nanoparticles. Self-assembly of the monodisperse hollow Fe3O4 nanoparticles leads to superlattice arrays (see TEM image). The synthesis offers a general approach to hollow iron oxide and core-shell-void Fe-Fe3O4 nanoparticles that may have potential applications in catalysis and high-frequency electromagnetic devices.
