Single-walled carbon nanotubes (SWCNTs) have been synthesized by an arc discharge method using asphalt and petroleum coke as the ?carbon sources. The morphology and structure of the SWNT products synthesized with iron (Fe) as the catalyst were characterized by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, and energy dispersive X-ray spectroscopy (EDX). Our findings indicate that asphalt and petroleum coke are suitable industrial carbon sources for the growth of SWCNTs.
