Outline of Final Research Achievements

In this study, we succeeded in observing various heteropoly acid assemblies at the atomic level by aberration-corrected transmission scanning electron microscopy (STEM), and show that STEM can be used for characterization of solid heteropoly acid catalysts. In addition, to develop catalytic materials, we tried to control the arrangement of heteropoly acid molecules and succeeded in synthesizing novel Keggin-type heteropoly acid nanosheets. Furthermore, we succeeded in detailed structural analysis of the nanosheets using STEM.

Academic Significance and Societal Importance of the Research Achievements

へテロポリ酸分子の直接観察が可能となったことにより、固体ヘテロポリ酸触媒のより詳細な構造評価が可能となった。これにより、高効率な固体ヘテロポリ酸触媒の開発が加速されると期待できる。また、電子顕微鏡による直接観察は、ナノ材料の構造評価に特に有効である。本研究の成果によって、ヘテロポリ酸分子の配列を制御した新規なナノ材料の開発が加速されると期待できる。
