    摘要: The present invention relates to a method for manufacturing a transition metal-carbon nanotube hybrid material using nitrogen as a medium. The present invention is characterized in that nitrogen-added carbon nanotube is grown in the presence of metal catalyst particles by reacting an hydrocarbon gas with a nitrogen gas by a chemical vapor deposition (CVD) and a transition metal-carbon nanotube hybrid material where a transition metal is uniformly attached to the entire carbon nanotube structure in which nitrogen with a great chemical reactivity is added as heterogeneous elements is chemically manufactured. Therefore, the present invention does not use an acid treatment required to attach transition-metal atoms to the carbon-nanotube, a surface treating process using a surfactant and the like and an inhibitor for preventing the coagulation of the transition metal so that a simplification of the process is obtained and the method is an environment-friendly method. The transition metal-carbon nanotube hybrid material manufactured by the above can be applied variously as a hydrogen storage material, a catalyst material, an electric field emission device and an electrode material.

    摘要: TiO2-xNx (0.01≦x≦0.2) nanotubes and a method for preparing the same are disclosed. More particularly, TiO2-xNx (0.01≦x≦0.2) nanotubes doped with nitrogen atoms by treating TiO2 nanotubes through nitrogen plasma to partially substitute oxygen portion of TiO2 nanotube with nitrogen, and a method for preparing the same are disclosed. The TiO2-xNx (0.01≦x≦0.2) nanotube of the present invention is prepared by doping nitrogen on a TiO2 nanotube to control an electronic structure and reduce a band gap of the TiO2 nanotube, so that the prepared TiO2-xNx (0.01≦x≦0.2) nanotube exhibits improved conductivity and extended light absorption range from a UV ray area up to a visible light area, thus having more enhanced applicable performance in optical and/or electrochemical aspects.
