The synthesis of carbon nanotubes (CNTs) from ethylene decomposition by Fe /Al O and Fe / Ni /Al O catalysts 2 3 2 3 (Fe:Ni510:1) is studied. A small amount of nickel introduced into the catalyst can significantly increase the yield of CNTs, but the nanotubes change from straight tubes with concentr
