Synthesis of carbon nanotubes using scrap tyre rubber as carbon source

Carbon nanotubes (CNTs) were successfully synthesized through chemical vapor deposition (CVD) method over cobalt catalysts using scrap tyre rubber as carbon source. The CNTs as produced were investigated by means of X-ray diffraction, thermogravimetric analysis, scanning electron microscope, transmission electron microscopy and Raman spectrum techniques. It was found that the obtained carbon material mainly existed in the form of CNTs.
