One-dimensional (1D) nanostructure of metal oxides and materials has been extensively studied about their high surface area, strong adsorption properties and the ability to produce more redox sites. Furthermore, 1D structure materials are used as the photocatalyst because of its more redox sites. In order to synthesize nano scale fibers, there are several methods such as electro-spinning, self-assembly, template synthesis and thermal-induced phase separation. In this study, we fabricated the nanofiber by TiO2 which composed of a metal oxide such as the oxide of silver, vanadium, iron and nickel through the electro-spinning which is the common method. Metal/TiO2 composites sol was spun in various voltage to fabricate nanofiber as thin as possible. As a result, the nanofibers formed at 15kV were the thinnest and most uniform before and after calcination. |
