Single stage production of carbon nanotubes using microwave technology

Carbon nanotubes (CNTs) were produced by gas phase single stage tubular microwave chemical vapor deposition (TM-CVD) using ferrocene as a catalyst and acetylene (C2H2) and hydrogen (H2) as precursor gasses. The effect of the process parameters such as microwave power, radiation time, and gas ratio o...
