Outline of Final Research Achievements |
A particular metal ion included as a constituent in a nonporous inorganic solid was chemically substituted with the smallest proton for forging a new path to obtain a new porous functional crystal. Cu5Ta11O30, one of two synthetic precursors, was subjected to the solvothermal treatment to form Cu-free H5Ta11O30. The hydroxyl groups on its surface are suggested to be involved in hydrogen generation observed when heating in a vacuum. As the H-D exchange of the group occurs in D2O, H5Ta11O30 will be the catalyst for D2 generation. On the other hand, we synthesized another functional solid with larger crystalline pores, K1-xHxNb5O13, which is obtained by substituting the K site of KNb5O13 with proton via the Ag-substituted intermediate. The porosity and photocatalytic ability were assessed.

Academic Significance and Societal Importance of the Research Achievements |
産業上有用なゼオライトは、主骨格元素の種類がSiとAlしかない。本研究では、元素範囲の拡大による用途の多様化を目指し、TaまたはNbを骨格元素とする多孔結晶を得る方法を開発しており、学術的に重要な取り組みの一つと考えられる。開発した物質はゼオライトにはない光触媒機能も示しており、社会的意義も大きいと想定される。
