Outline of Final Research Achievements

In this study, we developed new synthesis methods of brownmillerite-type or spinel-type solid solution oxides ultrasmall particles with single-nanometer dimensions, which are electrocatalysts for oxygen evolution reaction, using a reverse micelle method or a solvothermal method. Wavenumber of the ultrasmall particles of all solid solution oxides were shorter than those of the bulk ones. The catalytic activity of the solid solution oxides for oxygen evolution reaction were largely improved by decreasing particle size to with single-nanometers, and they acted as cocatalysts of photocatalysts for water splitting using visible light.

Academic Significance and Societal Importance of the Research Achievements

本研究では、これまで数nmスケールの超微粒子化が困難であった結晶性多元系遷移金属酸化物を3 ~ 9 nmの超微粒子にする技術を開発した。超微粒子化により結晶性多元系遷移金属酸化物の光吸収波長の短波長化と触媒活性の向上を見出し、また可視光応答型光触媒の助触媒として利用できることを明らかにした。これによりこれまで可視光応答型光触媒に利用されてこなかった多元系遷移金属酸化物触媒の新たな設計指針を見出した。
