Local trapping of energetic holes at gold nanoparticles on TiO 2

Oxidation sites for plasmon-induced charge separation at gold nanocubes and nanorods on TiO2 were visualized by PbO2 deposition, and the sites were localized at plasmonic resonance sites. This indicates that energetic holes generated at those sites dominate the reactions, which can be applied to pho...

Zusammenfassung:Oxidation sites for plasmon-induced charge separation at gold nanocubes and nanorods on TiO2 were visualized by PbO2 deposition, and the sites were localized at plasmonic resonance sites. This indicates that energetic holes generated at those sites dominate the reactions, which can be applied to photo-nanofabrication beyond the diffraction limit.
