Abstract: We have studied the growth of multiwall carbon nanotubes (CNTs), using graphene oxide (GO) and iron nanoparticles as catalyst for chemical vapor deposition (CVD) technique. This approach is based on covalent bonding between GO and acetylene (C2H2) gas molecules. Catalytic layers of GO and iron nanoparticles were fabricated on copper substrate using spin coater. Main reactions took place in CVD chamber under atmospheric pressure at 750 °C. Field emission scanning electron microscope (FESEM) explored the diameter distribution of successfully synthesized CNTs: 10-20 nm for GO and 29-47 nm for iron nanoparticles. X-ray diffraction spectra confirmed the presence of synthesized CNTs on both catalysts, as well as transformation of GO to reduced graphene oxide (rGO) during this process. ID/IG ratio was obtained through Raman spectroscopy, which revealed less defect contents in CNTs synthesized on GO in comparison to nanotubes grown iron catalyst. The main advantages of this innovative approach are simplicity, low cost due to one step technique, high yield and less defects. © 2016 Elsevier B.V. All rights reserved.
