| Research Abstract |
The present study hfaosund that Ti2 Oelectrodes modified with 25Aculusters generate photocurrent and photopotential in response to visible a-nidnfrnaeraerd light in the presence of hydroquinoneT.he internal quanutm efficiency of the photocurrent generationis as high as 6T0h%e.A2u5-TiO2 systems workas visible light-driven photocatalysts. Inaddition, this study hasucceeded in the determination of electronic structure25of Auclusters. Other metal elements shucas Ag, Cu, Pt, and Pd can also be utilized for the photoelectric conversion.Moreover, this study hassucceeded in the enhancement of photocurrent based on 25Auclusters by introducing localized electric fields induced byAu nanoparticles.
