Outline of Final Research Achievements

We focused on paramagnetic Fe (III) complex oxides as photocatalysts. Solid solutions of magnetic Fe (III) complex oxides and diamagnetic complex oxides were prepared and their crystal structures, band structures, and photocatalytic activities were investigated. As a result, changes in crystal structures and band structures, and photocatalytic activities due to iron substitution were observed obviously and the role of iron in photocatalyst was discussed. Some photocatalysts with higher activity were obtained by changing the preparation method.
