Abstract
Nanosized CeO2, and CeO2-SnO2, 100–500 nm thick, films on glass substrate were prepared using sol-gel dip-coating method procedure. The average grain size <R>, obtained by SAXS (small-angle X-ray scattering), varied with the number of dips for the CeO2-SnO2 samples. For the CeO2 films, obtained by dipping it 8 times, <R> increased compared to CeO2-SnO2 films, which were obtained by the same number of dips, from 4.4 to 5.3 nm. Specific surface areas of both these films were also determined and varied from 0.18 × 107 to 0.51 × 107 cm−1. SAXS measurements also revealed the layered structure of CeO2 and CeO2-SnO2 films.
