Surface-Mediated Visible-Light Photo-oxidation on Pure TiO2(001)

Surface-Mediated Visible-Light Photo-oxidation on Pure TiO2(001)

We used STM to observe visible light photo-oxidation reactions of formic acid on the ordered lattice-work structure of a TiO2(001) surface for the first time. The nanostructured surface makes the band gap significantly smaller than 3.0 eV only at the surface layer, and the surface state of the cryst...

Zusammenfassung:We used STM to observe visible light photo-oxidation reactions of formic acid on the ordered lattice-work structure of a TiO2(001) surface for the first time. The nanostructured surface makes the band gap significantly smaller than 3.0 eV only at the surface layer, and the surface state of the crystal enables a visible light response.
