Hot Electron Transfer

Taking brookite TiO2 with controlled band structure as example, it reveals that the accumulation of electrons will negatively shift the EF of Au caused by the intense light excitation, thus the effect of Schottky barrier will weaken and TiO2 with more negative reduction potential will exhibit higher activity.
