Abstract

Magnetic Fe3O4/multi-walled carbon nanotubes (MWNTs) nanocomposites have been fabricated by a green and simple hydrothermal method. It has been found that Fe3O4 nanoparticles with diameters in the range of 15-30 nm were firmly decorated on the external surfaces of MWNTs. The Fe3O4/MWNTs nanocomposites exhibited good ferromagnetic behavior with a high saturation magnetization of 55.833 emu/g and a coercivity of 97.062 G. Furthermore, the Fe3O4/MWNTs nanocomposites could be quickly separated or redispersed from aqueous solution with the application of external magnetic field..
