| Outline of Final Research Achievements |
This study aimed to study plasmonic chemical reactions in real-time and in operando conditions using a newly-developed time-resolved ambient pressure X-ray photoelectron spectroscopy. At the interface of Au nanoparticle and TiO2 which is one of the representative plasmonic nano-materials, I have succeeded in monitoring carrier injection from Au nanoparticles that are excited by a plasmon resonance to the TiO2 substrate in real time. In addition, I have developed time-resolved ambient pressure X-ray photoelectron spectroscopy and have succeeded in the first test measurement.
