| Outline of Final Research Achievements |
Hydrogen boride (HB) sheet was found to act as a solid acid catalyst. As a result of investigating the dehydration reaction of ethanol, it was found that the HB sheet has a reaction mechanism similar to that of H-type zeolite in terms of the role of Bronsted acid. In other words, it was shown that the hydrogen that constitutes the HB sheet participates in the dehydration reaction of ethanol, and boron, which is the lattice hydrogen-deficient position, abstracts hydrogen from the methyl group of the intermediate product to form ethylene. From this study, it was shown that in the future, by investigating the catalytic properties of HB sheets for various reactions, it is possible to find activities and selectivity that surpass those of existing catalysts.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により、2017年に我々が世界で初めて合成に成功したホウ化水素（HB)シートが金属や炭素を含まない固体酸触媒として機能することが世界で初めて明らかとなった．HBシートはブレンステッド酸の役割の観点でH型ゼオライトと似た触媒特性を示すこともわかった．本研究により，今後，さらに様々な反応に対するHBシートの触媒特性を調べることで既存の触媒を凌駕する活性や選択性が見出される可能性があることが示された．
