Abstract
In this study, carbon nanotubes coated with iron oxide nanoparticles were synthesized by a co-deposited simultaneous method with initial salt ratios of 2 to 1 and 4 to 1. In order to study the structural, surface and magnetic properties, electron microscopy, magnetic residue, infrared Fourier transform, Raman, x-ray diffraction, nitrogen adsorption-desorption, and zero-point calculations were studied. The results obtained from the structural analysis indicate that iron oxide nanoparticles with 12.2 nm and 13.5 nm are in the range of 2 to 1 and 4 to 1 on carbon nanotubes, respectively. Also, for these proportions, the behavior of superparamagnetic with saturated magnetization was 11.48 mg/g and 27.97 emu/g, respectively. The results showed that, by choosing the right method and optimizing the effective parameters in the method of synthesis of magnetic carbon nanotubes, it is possible to directly change their surface properties and, as a result, nanostructures with specific surface properties in the “Wide” range of laboratory conditions.
