Carbon nanotube was synthesized by decomposition of ethylene over oxidized diamond-supported catalysts at a relatively mild temperature. We focused inner structure of carbon nanotubes which were synthesized using Ni-Fe, Co-Fe, and Ni-Co loaded oxidized diamond catalysts. In these catalysts of Ni-Fe, Co-Fe, and Ni-Co-loaded oxidized diamond catalysts, oxidation state of loaded metals were compound oxide of NiFe2O4, CoFe2O4, and NiCo2O4, respectively. The oxidation state of loaded-bimetallic species might have played an important role in clear internal structure of synthesized carbon nanotube.
