Research Abstract

本研究ではSnP_2O_7に着目し、そのプロトン導電性に対する低原子価カチオンのドーピング効果を研究した。SnP_2O_7は通常のリン酸塩化合物と違って、二量体構造のP_2O_7^(4-)イオンから構成されており、しかもSn^(4+)イオンとP_2O_7^(4-)イオンがNaCl型構造を示すため、二量体イオンが単位格子中に密な状態で存在している。これによって、プロトンサイト密度が高くなり、またプロトンがサイト間をホッピングする経路が多くなる。さらに、In^(3+)、Al^(3+)、またはMg^(2+)のような低原子価カチオンをドープすることで、電荷補償としてプロトンが固体内に導入され、導電率が一桁以上増加する。また、ドーパントの塩基性度によって固体表面の酸性度も制御可能である。従来のプロトン導電体では、使用可能な温度領域がNafionに代表される100℃以下の低温領域と、BaCeO_3系ペロブスカイト型酸化物に代表される400℃以上の高温領域に限られていた。本研究の成果によって、これまで空白であった100-400℃での使用が可能となり、プロトン導電体の適用範囲を大いに拡張できるものと期待される。
