Catalytic synthesis of carbon nanotube over nickel ferrite loaded oxidized diamond catalyst

Abstract

Carbon nanotube was synthesized by decompn. of ethylene over oxidized diamond-supported catalysts at a relatively mild temp. 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, oxidn. state of loaded metals were compd. oxide of NiFe2O4, CoFe2O4, and NiCo2O4, resp. The oxidn. state of loaded-bimetallic species might have played an important role in clear internal structure of synthesized carbon nanotube. [on SciFinder(R)]
