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.
