| Outline of Final Research Achievements |
This research aims at realizing a visible-light photocatalyst consisting with low-cost and abundant materials. We chose iron oxide as a host material, however it is an insulator. To raise the conductivity, tin ions were doped to iron alloy oxides, as a result the conductivity increased of three or four orders of magnitude. On the contrary, the band gap of iron oxide must be widening because the energy level is not enough for water decomposition. Gallium oxides were being alloyed with iron oxides to widen the band gaps, thereby the band gaps were successfully tuned.
In this way, our research indicated great possibilities of iron oxide for applying a visible-light photocatalyst.
