title: Decoration of multiwalled carbon nanotubes with CoO and NiO nanoparticles and studies of their magnetism properties.
abstract: Multiwalled carbon nanotubes (MWNTs) have been successfully decorated with magnetic CoO and NiO nanoparticles via the interaction of M(NH(3))x(2+) (M = Co,Ni) ions and the carboxyl groups on the surface of acid-treated MWNTs. The obtained composites were characterized by X-ray diffraction, scanning electron and transmission electron microscopies. The soaking time plays an important role in the preparation of the composites. Magnetic measurements indicate that both the CoO/MWNT and NiO/MWNT composites present superparamagnetic behavior which can be attributed to the small size of CoO and NiO nanoparticles.
