| Outline of Final Research Achievements |
The present work dealt with highly-functionalized oxygen-storage materials (OSMs), which can reversibly store and release oxygen, for realizing innovative oxygen-gas production technologies. Our group focused on brownmillerite-type Ca2AlMnO5+d, aiming for lowered operation temperature and enhanced oxygen intake/release performance by means of chemical substitutions. The main achievements are as follows. (1) The oxygen intake/release temperatures were successfully lowered upon Ca-for-Sr substitution, retaining sufficiently high oxygen storage capacity. (2) For the pristine Ca2AlMnO5+d and its Sr-substituted phases, the rate limiting processes for the oxygen intake reaction were identified.
