Abstract: A method for manufacturing a transition metal-carbon nanotube hybrid material is provided to produce the hybrid material simply by the medium of nitrogen having high reactivity present within carbon nanotubes even without using a separate surface treatment or an inhibitor. A method for manufacturing a transition metal-carbon nanotube hybrid material includes a step of reducing a transition metal by a reduction reaction within a solution comprising nitrogen-containing carbon nanotubes and a transition metal salt. A nitrogen content in the carbon nanotubes is 0.01-20at%. A solvent forming the solution is polyol. The transition metal salt is an acetate or chloride salt. The nitrogen-containing carbon nanotubes are prepared by reacting hydrocarbon gas with nitrogen gas in the presence of a metal catalyst by plasma chemical vapor deposition.
