Abstract

Isolated iron(III)-oxo clusters were synthesized onto TiO₂ using atomic layer deposition. The Fe_xO_y/TiO₂ nanocomposites have unique properties that enable not only absorption of visible light, but efficient photocatalysis as demonstrated by methylene blue degradation. The localization of photogenerated electrons in core TiO ₂ nanocrystallites upon visible light excitation demonstrates coupling of conduction bands of mixed oxides. The redox properties of photogenerated charges in nanocomposites were studied using in situ electron paramagnetic resonance spectroscopy.
