| Outline of Final Research Achievements |
The present work dealt with development of functional ceramics named "oxygen-storage materials", which enable to produce hydrogen gas through thermochemical water dissolution. The double-perovskite type BaLnMn2O5 (Ln: lanthanoid elements) was found to show a capability to produce hydrogen gas through the water dissolution at 500C. It was found that the reactivity significantly depends on the Ln species: the large the Ln3+ ionic size, the higher reactivity the BaLnMn2O5 samples exhibit. Our quantum chemical calculations revealed that isovalent substitution at the Ln site influences greatly the redox characteristics of this material, implying the high availability of chemical composition control on materials tailoring.
