Abstract

After UV-irradiation of a TiO₂ shell on Pt anode was cut off, anodic current was observed continuously for some time because long-lived MV⁺˙ produced from MV²⁺ embedded inside the shell, as a result of the electron transfer from the conduction band of the irradiated TiO₂ shell, diffused slowly and discharged to the shell thus realizing electron accumulation inside the TiO₂ shell.
