Figure 7.

a and b TEM BFI and corresponding SAED pattern of the amorphous titanium oxide microtube (i.e. sample 4 in Table 1) on a carbon lacey support film, c lattice image with the intensity profile along the trace (red line, orthogonal to the elongate direction of the tube) inset showing the corrugated lamellar wall are 0.386 nm interspaced on the average ca. half that of the H2Ti3O7(0.786 nm) implying a close structure linkage (cf. text)
