Preparation of magnetic CoFe"2O"4 functionalized graphene sheets via a

Magnetic CoFe2O4-functionalized graphene sheets (CoFe2O4-FGS) nanocomposites have been synthesized by hydrothermal treatment of inorganic salts and thermal exfoliated graphene sheets. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations show that cobalt ferrite
