摘要：

We used STM to observe visible tight 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.
