Abstract: A two-step reaction was used for the synthesis of SiC nanorods. First, SiO vapour was generated via the silicon reduction of silica. Second, the generated SiO
vapour reacted with carbon nanotubes, which resulted in the growth of the single crystalline cubic β-SiC nanorods. The diameters of SiC nanorods ranged from 3~40nm.
A broad photoluminescence peak located around 430nm under 260nm UV fluorescent light excitation at room temperature was observed. The morphology and structure of the
nanorods were characterized by XRD, HREM and Raman spectroscopy. The growth mechanism of SiC nanorods was studied in detail.

Key words: SiC nanorods, carbon nanotubes, growth mechanism
