Outline of Final Research Achievements

Zeolite has been used as an industrial catalyst due to its nano-level crystalline ordered structure. However, its synthesis is based on trial-and-error, and it is still difficult to design its structure at the atomic level. Furthermore, to control its catalytic function based on the material design is also quite difficult. In this research, by utilizing a hydrothermal synthesis method and a new material with a two-dimensional structure, we attempted to design a zeolite structure, and combined it with multifaceted structural analysis results, to explore the catalytic properties of novel zeolites.
