Novel accumulation of photo-induced MV+* embedded in a TiO2 shell and discharge of electrons to a Pt electrode.
After UV-irradiation of a TiO(2) shell on Pt anode was cut off, anodic current was observed continuously for some time because long-lived MV(+)* produced from MV(2+) embedded inside the shell, as a result of the electron transfer from the conduction band of the irradiated TiO(2) shell, diffused slowly and discharged to the shell thus realizing electron accumulation inside the TiO(2) shell.
