| Abstract: | A magnetic multi-walled carbon nanotubes-based (MWCNTs-based) composite, MWCNTs/Ni0.5Zn0.5Fe2O4, was synthesized via a facile solvothermal approach. The composites were characterized by X-ray diffraction analysis, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and vibrating sample magnetometry. The results confirmed that MWCNTs and Ni0.5Zn0.5Fe2O4 coexisted in the composites. The TEM and HRTEM results showed a thick layer of Ni0.5Zn0.5Fe2O4 was intimately connected to the surface of MWCNTs. The saturation magnetization value of the composites was 45.8 emu/g. Furthermore, the probable synthesis mechanism of the magnetic composites was also investigated based on the experimental results. |
