In this study, the effect of carbon nanotube (CNT) supports on the morphology and structural of copper ferrite nanoparticles has been investigated. The synthesis of CuFe 2 O 4 nanoparticles has been done through direct precipitation in aqueous solution with CNT content. The morphology of the synthesised samples has been studied by the use of scanning electron microscopy; structural properties have been investigated through X-ray diffraction spectrometer. Fourier transform infrared spectroscopy apparatus was used to identify the functional groups on the surface of CNTs. The findings showed that the presence of CNT support in nanocomposite powder, the size of CuFe 2 O 4 significantly decreased and the powder morphology changed from agglomerate state to nanorodes.

In this paper, the effects of carbon nanotubes as a support to the morphology and size of Fe 3 O 4 magnetic nanoparticles have been investigated. The synthesis of Fe 3 O 4 /CNTs nanocomposite powder was performed by the direct precipitation method through ferric chloride (II) and (III) at room temperature. The prepared samples were analyzed by X-ray diffraction spectra, Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. The results demonstrated considerable changes in the Fe 3 O 4 nanoparticle size, also the morphology of Fe 3 O 4 /CNTs nanocomposite powder from agglomerative into rode shape.

In this paper, the effects of carbon nanotubes (CNTs) were studied as supports for the synthesis of MnFe 2 O4 nanocomposite. The synthesis of nanocomposite powder MnFe 2 O 4 /CNTs was performed by direct precipitation method in aqueous solution. The prepared samples were analyzed by X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The results represent the considerable change in the MnFe 2 O 4 nanoparticle size and also the morphology of MnFe 2 O 4 /CNT nanocomposite powder from agglomerative into nanorod in shape.
