Abstract:

Using TiO2 nanowires and Fe(NO3)3·9H2O as raw materials, Fe3O4 nanoparticles/TiO2 nanowires hybrid nanostructure was fabricated in a system with diethylene glycol as the solvent. High-resolution transmission electron microscopy(HRTEM) observation demonstrates that the Fe3O4 nanoparticles are addressed on the TiO2 nanowires. Effective connection forms between the Fe3O4 nanoparticles and TiO2 nanowires. Magnetic study shows that the hybrid nanostructure’s blocking temperature is significantly lower than that of pure Fe3O4 nanoparticles with the same diameters.

Key words: Nanomaterial, Hybrid nanostructure, Magnetic property, Blocking temperature
