Outline of Final Research Achievements |
In this study, we constructed photocatalytic reaction systems utilizing hot electron transfer from gold nanoparticles to the conduction band of titanium dioxide based on the gold nanoparticles-loaded titanium dioxide substrate. We measured the photocatalytic reaction process using various spectroscopic methods and transmission electron microscopy for elucidating the dynamics of hot electron transfer at the interface as well as discussing the reaction scheme by the remained holes and clarified the design guidelines for highly efficient plasmon-induced photocatalytic reactions.
