Figure 2.

TEM images of as-synthesized bare TiO2NPs (a) and the hydrothermally treated TiO2NPs (b). The latter (in a mixture of EtOH/H2O = 1:1.5 at 150 °C for 24 h) are from a simple stoichiometric non-synchronous feeding where the equivalent mole of Li2O and TiCl4 solutions were fed at a molar rate of MLi2O/MTiCl4 = 2:1.
