Processes for fabricating highly ordered, large-scale TiO 2 nanowire arrays. (a) Schematic diagrams of the process to produce the nanowire arrays, (b) photograph of a 2 cm × 2 cm AAO template, (c) top view of the AAO templates after coating TiO2 via (i) sputtering and (ii) ALD with a mean pore diameter of 67 nm, and (d) top and cross-sectional SEM images of the highly uniform and free-standing TiO2 nanowire arrays.
