dc.abstract.en Abstract Image Substitution of surface −OH groups of TiO2 may influence competition between photoinduced energy and electron-transfer processes and lead to improved singlet oxygen generation. In contrast to neat TiO2, 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 TiO2 (F−TiO2) in which “bulk” hydroxyl radicals play a key role. It seems plausible that the difference of activity observed for TiO2 and F−TiO2 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
