One-dimensional (1D) TiO2 has attracted intensive scientific interest because of its unique properties due to the confinement effects and large specific surface area which is key parameter in enhancing the effectiveness of TiO2 in various application. Common fabrication method for the 1D nanomaterials is the template-based synthesis using porous membranes. When the precursor solution is introduced into the pores of the template, 1D nanostructure can be easily generated and its size can be controlled by the template pore sizes. In our work, 1D hierarchical titania nanostructures are prepared by filling the template pores containing colloidal particles as another template with the precursor solution including the block copolymers as structure-directing agents. Consequently, 1D hierarchical titania nanostructures were fabricated by the combination of sol-gel reaction and block copolymer self-assembly. The characteristics of 1D hierarchical titania nanostructures were examined by FE-SEM. |
