| Abstract: |
This work investigates the construction of a cold wall chemical vapour deposition system for producing carbon nanotubes and carbon nanofibers from a solid carbon source, camphor. A high temperature ceramic heater was fabricated and utilized inside a 50 mm diameter quartz tube. This reaction takes place within an argon environment with no gas flow during the growth process. Ferrocene was used in the formation of iron nanoparticles on a zeolite substrate. The effects of reaction temperature on the produced carbon species were investigated using Raman spectroscopy and scanning electron microscopy. Carbon nanotubes as well as likely metal oxide nano-wires were successfully grown and identified using Raman spectroscopy and scanning electron microscopy. This work demonstrates that solid carbon sources can be used in a cold wall reactor designed to produce carbon nanomaterials. The reactor design is inexpensive and easy to construct with sufficient technical skills. |
