Substitution of surface −OH groups of
dc.abstract.en | Substitution of surface −OH groups of $TiO_{2}$ may influence competition between photoinduced energy and electron-transfer processes and lead to improved singlet oxygen generation. In contrast to neat $TiO_{2}$, surface modified titanium dioxide can photocatalyze degradation of a very stable substance, cyanuric acid. Presented results are in contradiction to usually accepted hypothesis of the mechanism of cyanuric acid photodegradation in the presence of fluorinated $TiO_{2}$ (F−$TiO_{2}$) in which "bulk" hydroxyl radicals play a key role. It seems plausible that the difference of activity observed for $TiO_{2}$ and F−$TiO_{2}$ is not related to various types of generated hydroxyl radicals, but rather to competition between electron-transfer processes (formation of radicals) and energy-transfer processes (formation of singlet oxygen). | pl |
