Triangular nanohole array structures with high aspect ratios were fabricated by anodization of pretextured Al in an oxalic acid solution. By using the obtained anodic porous alumina with triangular openings as templates, an ordered array of TiO2 nanocylinders with triangular cross sections was fabricated. The preparation of TiO2 nanocylinders was carried out through the electrodeposition of TiO2 into the alumina nanoholes. The shapes and sizes of the obtained TiO2 nanocylinders were in good agreement with those of the pores of the alumina template. The triangular shapes of the TiO2 nanocylinders were successfully maintained even after heat treatment for crystallization to anatase from amorphous. The obtained TiO2 nanocylinders were isolated, and yielded the shape- and size-controlled TiO2 nanoparticles.
