Femtosecond Spectroscopy of Au Hot-Electron Injection into TiO<sub>2</sub>: Evidence for Au/TiO<sub>2</sub> Plasmon Photocatalysis by Bactericidal Au Ions and Related Phenomena

Femtosecond Spectroscopy of Au Hot-Electron Injection into TiO<sub>2</sub>: Evidence for Au/TiO<sub>2</sub> Plasmon Photocatalysis by Bactericidal Au Ions and Related Phenomena

In the present work, we provide evidence for visible light irradiation of the Au/TiO<sub>2</sub> nanoparticles&#8217; surface plasmon resonance band (SPR) leading to electron injection from the Au nanoparticles to the conduction band of TiO<sub>2</sub>. The Au/TiO<sub&...
