“…DSC thermograms show two thermal transitions: i) the T m of PEO blocks in T1107 at 50–52 °C and ii) the phase transition from amorphous TiO 2 to crystalline anatase at T > 300 °C ( Figure A) . These results indicate the amorphous nature of the ceramic component in the hybrid nanoparticles.…”

“…Furthermore, highly crystalline materials are of great importance for the effective photocatalysis. In general, nanosized anatase TiO 2 demonstrates the photocatalytic performance inferior to that exhibited by other phases (amorphous, rutile, brookite) or bulk material . However, it is worth mentioning that the photoactivity of low crystalline titanium‐based materials is still debatable in the literature.…”

“…Figure shows the FT‐IR spectra of the TiO 2 ‐NPs. The typical bands at ∼3400 cm ‐1 (stretching modes) and ∼1630 cm ‐1 (bending modes) can be resulted from the presence of water/hydroxyl groups which remain on the material surface even after the thermal treatment …”

“…While the NPs crystalline core is essentially constant, the structure of the shell depends strongly on its size. A great number of structural defects, including under-coordinated sites (like TiO 3 , TiO 4 , or TiO 5 ) and dangling bonds, are present in the shell and play a determinant role in the properties of a-TiO 2 NPs [25]. Atomistic modelling simulations also predict a distorted octahedral structure for the core (with Z Ti-O ~6.0 and Z O-Ti ~3.0), with a more porous structure for the shell, with a large number of structural defects (with Z Ti-O ≠ 6.0 and Z O-Ti ≠ 3.0) [39,40] and a density value (3.74 g/cm 3 ) lower than for bulk anatase (3.90 g/cm 3 ).…”
