摘要：
The Fe@gamma-Fe2O3 core-shell nanoparticles were synthesized by an electrochemical anodization method in a potentiostatic way. The core-shell structure was clearly shown by the HRTEM observation; With increasing the anodization potential and time, the thickness of gamma-Fe2O3 shell increased, which was proved by the measurements of XRD and magnetization. Compared with the naked Fe nanoparticles, the anodized Fe@gamma-Fe2O3 core-shell nanoparticles show the better magnetization stability and can be more easily functionalized by TiO2.
