Fig. 9(a): SEM image of a fishbone structures of TiO2 layer formed on Ti by anodization in 10 wt% K2HPO42O2 for 7 h. The upper and lower insets show layers formed by anodization for 24 and 48 h, respectively. The inset on the top right is the magnified SEM image of (a). The potential is applying 50 V with one step from open circuit potential (OCP).1 (b) Highly regular TiO2 mesoporous structures formed on Ti by anodization in 10 wt% K2HPO4 in glycerol at 180 ± 1 °C and after etching in 30 wt% H2O2 for 1 h.2 (c,d): Bamboo-type tubes, grown under AV conditions, with a sequence of 5 min at 120 V and 5 min at 40 V for 4 h anodization (c) and 1 min at 120 V and 5 min at 40 V for 12 h (d).3
