Surface| Summary: | Defective structures of the mixed oxides TiO2/ZrO2, TiO2/SiO2, SiO2/ZrO2 and TiO2/ZrO2/SiO2 are studied by EPR method. The character of defects formed during the sol-gel synthesis and subsequent heat treatment, and the influence of high-energy radiation on the defect structure of the obtained composites were determined. Ternary system is more stable (paramagnetic centers are formed only on titania surface) unlike the binary systems were the appropriate defects of both components are observed after irradiation. |
