Abstract
A range of pure metal and metal compound catalysts have been investigated for chemical vapor deposition (CVD) growth of multi-walled carbon nanotubes on silicon oxide substrates under various conditions. Catalysts including iron, cobalt and nickel and their carbonyl, chloride, oxalate and acetylacetonate compounds deposited on SiO 2 substrates were prepared and reduced in flowing hydrogen prior to nanotube growth from hydrogen and acetylene at temperatures ranging from 500 to 750 °C. The highest quality nanotubes were grown from elemental iron and iron compound catalysts at temperatures around 700 °C.Keywords
