| Abstract: | Carbon nanotubes coated inside with iron and cobalt nano-particles was synthesized with anode-arc discharge method. The transmission electron microscopy (TEM), X-ray diffraction(XRD), and Raman spectroscopy were used to identify and characterize the products. The product was multi-walled carbon nanotubes with average diameter of 35 nm. Dispersed Fe and Co nanoparticles could be found inside the tubes and at their ends and the sizes of coating nano-particles varied from several to tens of nanometers, being approximately 20 nm in average. The formation mechanism of carbon nanotubes coated with metallic nano-particles by using anode-arc discharge method was analyzed. |
