✦ Synopsis

High-quality single-walled carbon nanotubes (SWCNTs) have been synthesized by using self-designed high-frequency-induction heating equipment rapidly. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy and thermal gravimetric analysis (TGA) were used to characterize the produced SWCNTs. The results indicate that SWCNTs synthesized by this technique have higher purity (about 95%), smaller diameter (0.8-1 nm) and lengths up to 10 mm. The reasons for synthesis of smaller diameters and higher purity SWCNTs by using this technique are also discussed. This novel synthesis technique presents a potential opportunity for cost-effective and commercial production of SWCNTs.
