    摘要： Disclosed are partially deactivated metal catalysts useful for modifying structures of nanomaterials. The present invention is also directed to a method for preparing the partially deactivated metal catalysts, which comprises patterning a substrate with micelles containing iron nanoparticles, removing the micelles from the patterned substrate to deposit the iron nanoparticles thereon, nitriding the iron nanoparticles using a nitrogen plasma, and exposing the nitrided iron nanoparticles to a mixture of ethanol and nitric acid to remove iron from the surface of the nitrided nanoparticles. The iron nitride metal catalyst with a nano-size according to the present invention comprises a core that includes deactivated iron nitride and an active shell surrounding the core. Thus, when preparing a carbon nanotube, the metal catalyst can be effectively used to control the number of walls formed in the carbon nanotube.

    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.
