Direct Synthesis of Nanocables of Single-walled Carbon Nanotubes Sheathed with Amorphous Silica
نویسندگان
چکیده
Coaxial nanocables of single-walled carbon nanotubes (SWNTs) sheathed with amorphous silica were synthesized by using an arc discharge method. The as-obtained nanocables were characterized by TEM, SEM and laser Raman. It was found that the nanocalbes are usually tens of microns in length and about 50 nm in diameter, and each of the cylinder-shaped nanocabels contains one to several SWNTs at the center part. The growth mechanism of the nanocables is proposed. These SWNT/amorphous silica nanocables may have potential applications in field effect transistors and other related nanodevices.

Sol-Gel Synthesis and Characterization of Co-Mo/Silica Catalysts for Single-Walled Carbon Nanotube Production
A series of silica-supported Co-Mo samples prepared by the sol-gel method has been compared as catalysts for the synthesis of single-walled carbon nanotubes (SWNT). The concentration ratio of ammonium hydroxide to the silica precursor tetraethoxysilane (TEOS) has an important effect on the resulting morphology of the silica support and, consequently, on the nature of the Co-Mo catalytic species...
