| Outline of Final Research Achievements |
This study proposed a solid-phase deoxidization method using a reducing agent of carbon for fabricating hollow nanostructures. The simple principle provides the advantages of a high degree of freedom of material selection. With the demonstration of fabricating various hollow nanostructures, the mechanical properties were evaluated, and the application of the nanostructures was discussed. The use as initial templates of CuO nanowire, ZnO nanowire array, and polymer nanofiber, in combination with the coating of carbon film, successfully produced various structures of Pt nanotube, Pt nano-porous film, Pt/Ag double-layered nanotube, and silica nanotube. Carbon atoms in the film easily diffused in the template to reduce the oxide during heat treatments. The silica nanotube was found to be useful for the second template to yield Cu nanofiber, where Cu was deposited inside the nanotube by means of electroless plating.
