Interfacial photoannealing: the light driven alteration of the surface-binding geometry of a mixed-valence complex capable of multielectron charge transfer on colloidal TiO(sub 2)

Article Abstract:

Mixed-valence complexes have attracted significant interest in recent years, due to their potential application in solar energy conversion, photocatalysis, and molecular electronics. The UV/vis absorption and resonance Raman spectra changes are explained in terms of a rearrangement of the surface-binding geometry of the complex, resulting in the selectivity of electron-transfer direction within the complex.z

Photoinduced redox reaction coupled with limited electron mobility at metal oxide surface

Article Abstract:

A study is conducted to investigate the photoinduced oxidation of trimethyl acetate (TMA) on an atomically flat surface of rutile TiO2. The limited surface mobility of electrons photoexcited and trapped at OH-associated Ti sites is proposed to cause the temporal and spatial modulations.
