Outline of Final Research Achievements

Zeolites, crystalline inorganic porous materials, are important materials widely used as catalysts, adsorbents, and ion exchangers. In this study, we developed zeolite synthesis and functionalization methods by effectively using concerted assembly of simple molecules and ions (defined as "ensemble templating") and elucidated its mechanism. Specifically, zeolite synthesis methods, which had previously been problematic due to its high synthesis cost and the need for hazardous substances were improved, and extremly stable zeolites were developed through a post-treatment method.

Academic Significance and Societal Importance of the Research Achievements

環境問題やエネルギー問題の解決に向けて、ゼオライトは有害物質や温室効果ガスの除去、これらの無害化、さらには有用物質への変換といったプロセスにおいて重要な役割を担っている。これまでに多くの研究がなされているが、一方で実用化への障害となる高コストや有害な原料などとった課題も多く残されていた。本研究の成果は、これに一石を投じ、シンプルな分子やイオンを適切に使いこなすことでこれまでにない合成法や高機能化手法が可能であることを示した。
