| Outline of Final Research Achievements |
The ultimate goal of this task is to provide a preparation technique of zeolite catalyst that can be readily utilized in general, and to contribute not only to basic research but also to the acceleration of catalyst development and social implementation that are closer to industrial applications. In this connection, hierarchical structure was successfully created in YNU-5 zeolite by a direct base-treatment. The mesopore/micropore hierarchical structure in the YNU-5 zeolite catalyst suppressed deactivation more than the non-hierarchical, dealuminated YNU-5 with a similar Si/Al ratio.

| Academic Significance and Societal Importance of the Research Achievements |
新規骨格をもつYNU-5ゼオライト触媒の高性能化へのアプローチとして，ごく普通の塩基処理とそれに続く酸処理によって，有効な酸点を保持しつつ粒子内の拡散性を向上させうる階層構造を導入できたことは，本触媒の実用化へ向けても有意義なことである。YNU-5の特異なYFI骨格に由来する強い酸点について，学術的にも興味深い事実が最近見つかっており，今後の展開が期待できる。また，YNU-5の合成のために複雑な構造規定剤を有機合成する必要は無く，再現性も比較的高いことは，社会実装へ向けて有利な要素と言える。以上より，本研究成果の学術的意義や社会的意義は大きい。
