Sažetak
Nanosized TiO2 was prepared using a sol-gel procedure. The colloidal suspension was stabilized with hydroxypropyl cellulose (HPC). This polymer prevents sintering of TiO2 particles during the heating of the starting material in the form of a solid film. The TiO2 crystallite size increased from 5 to 12 nm with increase of temperature up to 500 degrees C, as determined by X-ray diffraction. XRD phase analysis showed that the studied samples were a mixture of anatase, as the dominant phase, and brookite. A new approach to size determination of nanophase TiO2, by low-frequency Raman scattering, was used. [References: 23]
