From: Influence of Anodic Conditions on Self-ordered Growth of Highly Aligned Titanium Oxide Nanopores
Top-view SEM images for the self-organized nanoporous titanium oxide templates obtained by anodization processes: (a) self-aligned and randomly disordered nanoporous titania template after being submitted a single anodic process in hydrofluoric acid solution for 90 min at RT; (b) in a mixture of hydrofluoric plus sulphuric acid solution during 18 h at RT; and (c) similar treatment to (b) at 4 °C, respectively. Their corresponding histograms with the pore diameter distribution of the so-formed TiO2nanopores are also shown
