| Summary: | Carbon nanotubes (CNTs) were synthesized using ferrocene as a function of catalyst. The process was performed at the temperature range between 800°C-1000°C in a thermal chemical vapor deposition chamber. The catalyst was placed in a boat at furnace 2. Camphoric carbon was used as the carbon precursor and the argon was adopted as carrier gas. Different parameters such as temperature, time process, carrier gas flow and the amount camphor were investigated and the relationships with the total amount product were found. CNTs with different characteristics were observed by varying parameters. The synthesized CNTs were characterized by Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and High-Resolution Transmission Electron Microscope (HRTEM). Micro-Raman spectra of these synthesized CNTs were taken on the Raman spectrometer (Raman). Energy dispersive X-ray analysis was performed by X-ray micro analyzer (EDX) attached to the SEM unit. |
