Abstract:
The samples of 5%TiO2/SiO2 prepared by sol–gel method from inorganic precursors calcinated at the various temperatures were studied by XAFS spectroscopy at Siberian Synchrotron Radiation Center. It was established that structural lability of this system and the change of symmetry of the oxygen coordination around the Ti(+4) ions depends on the calcination temperature. It seems that the mechanism of dissolution of the Ti(4+) ions in SiO2 depends on the calcination temperature and consists in the formation of Wadsley defects following the incorporation of SiO2 in TiO2 particles.
