Outline of Final Research Achievements

In this study, we investigated methods for assembling heteropolyacid molecules in order to fabricate Keggin-type heteropolyacid membranes with catalytic activity. It was clarified that a film can be formed by adding an alkylamine to an aqueous solution containing Keggin-type heteropolyacid and alkali metal salt. Furthermore,  by improving the observation conditions of scanning transmission electron microscopy, we succeeded in atomic resolution observation of aggregates of heteropolyacid molecules.

Academic Significance and Societal Importance of the Research Achievements

本研究ではへテロポリ酸分子を二次元的に集積するための条件を明らかにし、新規な集積体を開発した。この成果は、新規な固体ヘテロポリ酸触媒の開発につながると期待できる。また、本研究では、走査透過電子顕微鏡の観察条件を検討したことにより、電子に弱いヘテロポリ酸集積体の原子レベルでの構造評価を可能とした。これにより、ヘテロポリ酸触媒のより詳細な構造解明に繋がると期待できる。
