Synthesis and Characterization of A Nanocomposite Containing CNT

In this work, a one step and facile approach was used for the synthesis of magnetic multiwalled carbon nanotubes on the surface of diatomite earth as a substrate by chemical vapor deposition (CVD) of methane. The prepared composite was characterized by Fourier-transform infrared spectroscopy (FT–IR), X–ray diffraction (XRD), transmission and scanning electron microscopy (TEM, SEM), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), and Raman spectroscopy analyses. This new material combines the advantages of carbon nanotubes and diatomite in one material. The composite exhibited superparamagnetic properties. The magnetic hysteresis loops of the diatomite–CNTs composite and acid activated particles illustrated that the saturated magnetizations (σs) are 13.79 and 10.78 emu/g, respectively.
