Notes:
A novel nano-material of carbon rod studded iron granules on its surface was prepared fromneedle coke with iron as catalyst by arc method in the vacuum condition. Its structure and compositionwas characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM),energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). In the SEM images the carbonmaterial showed cotton-like. The TEM results showed that the nano-material was bar-like with diameterof 20nm to 50nm and there were lots of iron particles studded on its surface. The analytical result of EDSshowed that the chemical composition of materials mainly consisted of carbon and iron elements. TheXRD analysis revealed that there were two sharp diffraction peaks, one was at 26.2° which correspondedto the (002) plane of graphite structure and the other was at 43.2° which corresponded to the (fcc) γ-Festructure. The nano-material might be used as catalyst in the chemical reaction
