Synthesis and Characterization of CNT/Fe 3 O 4 -ZnS Nanocomposites

ZnS was coated on carbon nanotubes (CNTs) that had been previously functionalized with Fe3O4 nanoparticles. The as-synthesized products were characterized by X-ray diffraction (XRD), transmission electronic microscope (TEM) and physical properties measurement system (PPMS). ZnS nanoparticles with sphalerite structure are successfully assembled on the surface of CNTs/Fe3O4 nanocomposites. The CNTs/Fe3O4-ZnS nanocomposites exhibit superparamagnetic behavior with saturation magnetization of 21.25emug1. The as-synthesized nanocomposites have great potential for applications in the field of wastewater treatment, electronic devices, sensors and biotechnology.
