Outline of Final Research Achievements

Control of morphology for high-pressure synthesized materials was investigated. Significant increase in surface area was achieved by using high-pressure and room-temperature method. Furthermore, a cubic perovskite with high oxygen content was successfully obtained by using high-pressure and moderate-temperature method.

Academic Significance and Societal Importance of the Research Achievements

高圧合成法を活用し、新しい触媒材料の合成手法の開発を目的に研究を行った。粗大粒からなる低比表面積の試料を、高圧室温条件で処理することで微粒化し、10倍程度大きい比表面積を有する試料を得る方法の開発に成功した。また、高圧合成時の処理温度を精密に制御することで、結晶中の酸素欠損量が少ない酸化物試料の合成に成功した。いずれも酸化物などの材料合成において新しい学術的知見であり、高圧を用いた粉体処理への応用などが考えられる。
