Outline of Final Research Achievements

Sodium tantalate (NaTaO3) is the first semiconductor photocatalyst which produces hydrogen-oxygen mixed bubbles in the overall water splitting reaction, when properly doped with metal cations. This research project has been organized to answer the question of why doping with metal cations raised the quantum efficiency of the reaction. In-depth studies focused on Sr cation doping revealed that the electron-hole recombination rate was reduced when Ta cations were exchanged with Sr cations. Sodium cations were simultaneously exchanged to balance the cationic and anionic charges to form NaTaO3-Sr(Sr1/3Ta2/3)O3 solid solution. In addition, the intra-particle distribution of Sr cations played an essential role. Strontium cations segregated to produce graded composition from the Sr-rich surface to the Sr-poor core. The bottom of the conduction band lifted up at the Sr-rich surface, and the excited electrons were driven to the Sr-poor core leaving holes at the surface.

Academic Significance and Societal Importance of the Research Achievements

太陽光による水素燃料合成(広い意味での人工光合成)の実用化をめざした光触媒材料の探索がすすみ、波長の短い紫外光をエネルギー源とする水素製造の効率は、半導体光触媒がはじめて開発された50年前には考えられなかったほど高い水準に到達した。この高効率を維持しつつ、より波長の長い太陽光で励起できる材料の開発が世界中で進められている。しかし、収率向上の学理はいまだ解明されておらず、指針のない状況での開発は試行錯誤の連続とならざるをえない。本研究の成果として提案した金属カチオンドーピングによる効率向上のしくみは、光触媒のサイエンスを一歩前進させるとともに、現在進行中の材料開発に指針を提供する意義をもつ。
