|Title:||Growth Of Carbon Nanostructures By Thermal Chemical Vapor Deposition Via Metal Catalysis|
|Abstract:||Multiwall carbon nanotubes (MWCNTs), carbon nanofibers (CNFs) and carbon nanosprings (CNCs) were grown by changing the experimental conditions of the thermal chemical vapor deposition process. These experiments were performed using a tubular furnace and methane or acetylene as carbon feedstock gases. Thin films of Ni, Fe or Cu were deposited onto a SiO2/Si substrate and employed as catalysts. The effect of the growth temperature, metal catalyst and carbon gas precursor on the final carbon nanoestructured material was studied by scanning electron microscopy and Raman spectroscopy.|
