    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 inventions are a method for production of hydrogen which decomposes water into hydrogen by oxidation of metals only when the metals are exposed to the water, while preventing oxidation of pure metal nanoparticles using block copolymers and, in addition, hydrogen produced by the method described above. The method of the present invention has advantages of improved convenience and simplicity, achieves a preferable approach for hydrogen storage because the metal nanoparticles enclosed by the block copolymer have the ease of delivery and reaction thereof. Additionally, the method of the present invention only using water and the metal is considered eco-friendly and useful in industrial energy applications.
