Nanosized TiO2, 1 mm thick, films on glass
substrate were prepared using chemical vapour deposition (CVD) and spray method procedure.
The average grain size < R > ,
obtained by grazing-incidence small-angle scattering of synchrotron radiation (GISAXS)
varied with the annealing temperature (500 to 900 °C
in H2, O2 and N2) for the CVD prepared samples. For TiO2
films obtained by the spray method, < R
> increased with annealing temperature from 4.2 to 7.2 nm. Specific surface
areas of both films were also determined and varied from 0.18·107 to 3.2·107
cm-1.
