Outline of Final Research Achievements

α-Fe2O3, which works under visible-light, is one of the candidates. Up to now, α-Fe2O3 has relatively low photocatalytic activity due to that created carriers are easily recombined. It was found that a specific structure containing a α-Fe2O3 layer with surface roughness exceeding 100 nm and a Fe3O4 layer with an inclusion of Ge was formed and exhibited electrical rectification, when Ge-added Fe3O4 thin films were heat-treated in air. It was revealed that the specific structure exhibited photocatalytic activity under visible-light, when LED white light was irradiated to a designed container, in which a formaldehyde gas was inserted.

Academic Significance and Societal Importance of the Research Achievements

光触媒として普及しているTiO2は紫外光応答型の材料であるため,現在、可視光応答型の光触媒材料が盛んに研究されている.α-Fe2O3は候補材料の一つであるが,荷電担体の移動度が比較的低く光触媒機能に課題があった.本研究課題において提案した手法は、申請者の研究過程において独自に見出され,鉄酸化物から構成される特異構造を比較的簡単に作製することが可能である。したがって,当該材料を可視光応答型光触媒に応用できる可能性があり,また,ありふれた元素である「鉄」を利用することから、サステナブル社会の実現に寄与すると考えられる.
