TiO2 nanomaterials were prepared according to known procedures
[30–32] and their major physicochemical and textural
properties are summarised in Table 1. TEM analysis showed a monomodal size distribution for TiO2 NPs with a mean diameter of 1.6 ± 0.4 nm. In the case of NTs, a mean diameter was estimated at 60.5 ± 7.0 nm, whereas for the NFs, it was 138.3 ± 1.2 nm (Fig.S1).
