Outline of Final Research Achievements

Water jet cavitation (WJC) bubbles are generated when high-pressure water is jetted in water. When ultrasonic waves are applied to these WJC bubbles, they become the multifunction cavitation (MFC) bubbles. These MFC bubbles have high temperatures (several thousands of degrees Celsius) and high pressures (tens of thousands of atmospheres), so the material surface can be processed at high temperature and high pressure. In this research, we have improved the processing capability of MFC, and using this MFC, we have created a photocatalytic material that can decompose water when exposed to sunlight and efficiently generate hydrogen (clean energy). In addition, we produced a hydrogen storage material that can store a large amount of hydrogen by MFC processing.

Academic Significance and Societal Importance of the Research Achievements

水中で発生し、圧力と温度が非常に高い泡を用いた材料加工法(機能性キャビテーション:MFC)法は、本研究の代表者が世界に先駆けて開発した技術です。本研究では、MFC気泡の加工能力を更に高め、将来の水素社会で必要とされる、クリーンエネルギー水素を効率良く発生させ、多量に貯蔵できる材料を作製しました。また、大型MFC加工装置に加えて小型MFC加工装置を開発したため、従来行ってきた金属等の機械材料の機能を高めることに加えて、粉末加工、分子構造の変更など、化学やバイオ等の幅広い分野へ応用することができるようになりました。
