Outline of Final Research Achievements

Nanoscale open spaces formed by partial overlap of two-dimensional nanosheets in clays, abundantly and ubiquitously available, possess reactive molecular sites such as nanosheet edges in their interior. Here, the capture and storage of CO2 molecules in open spaces within saponite clay are explored by solid-state nuclear magnetic resonance coupled with open space analysis using positronium. CO2 physisorption occurs on the nanosheet surfaces inside the open spaces under ambient conditions. Thereby, CO2 molecules are activated by picking off weakly-bound oxygen from octahedral sites at the nanosheet edges and carbonate species are stabilized on the nanosheet surfaces. It is found that the above CO2 adsorption is sensitively influenced by the Cs concentration.

Academic Significance and Societal Importance of the Research Achievements

粘土鉱物のようなごくありふれた物質に対して,基本ユニットである二次元ナノシートのオーバーラップにより作り出されるナノ空間および空間内表面の局所構造を明らかにしたこと,そこで特異的な二酸化炭素吸着能があること,さらに二酸化炭素吸着能がセシウムイオンなど層間のアルカリ金属イオン濃度に敏感に影響されることを見出したことは学術的に意義がある。本研究で見出した二酸化炭素吸着は酸性溶液等を用いることなく常温・常圧で即座に起こる。このことは,エネルギー消費を伴わず,さらには廃液排出もなく二酸化炭素固定化が実現することを意味しているおり,カーボンリニュートラルの観点からも意義がある.
