%0 Journal Article %T Effect of the ratio of catalyst to carbon source on the growth of vertically aligned carbon nanotubes on nanostructured porous silicon templates %A Noor Asnida Asli %A Muhammad Salleh Shamsudin %A Suriani Abu Bakar %A Mohamad Rusop Mahmood and Saifollah Abdullah %J International Journal of Industrial Chemistry %D 2013 %I %R 10.1186/2228-5547-4-23 %X These data revealed that the amount of catalyst used significantly affected the diameter, crystallinity and growth rate of the synthesised nanotubes. The average diameter of the nanotubes ranged from [almost equal to] 9 to 30 nm with lengths of [almost equal to] 110 mum when 0.5 g ferrocene was used. %U http://www.industchem.com/content/4/1/23/abstract
