首次通过实验和理论手段在 α-Te2MoO7 中证明了固体中四价碲离子的传导。尽管人们普遍认为Te4+离子由于价态较高而在固体中不会明显导电，但这种导电可以在固体α-Te2MoO7中成功实现，其具有有利于离子迁移的二维层状结构。实测固体α-Te2MoO7(1.0 × 10–2S cm–1at 530 °C)中Te4+离子电导率达到了实际应用所需的阈值。直流电解结果直接提供了 α-Te2MoO7 中 Te4+ 离子传导的证据，理论上通过 MEM 分析提供了证据。
Tetravalent tellurium ion conduction in solids has been demonstrated in α‐Te2MoO7by both experimental and theoretical means for the first time. Although it has been commonly considered that the Te4+ion will not conduct appreciably in solids due to its high valency, such conduction can be successfully achieved in solid α‐Te2MoO7, which has a 2D layered structure conducive to ion migration. The measured Te4+ion conductivity in solid α‐Te2MoO7(1.0 × 10–2S cm–1at 530 °C) reaches the threshold required for practical applications. Evidence for Te4+ion conduction in α‐Te2MoO7is provided both directly by DC electrolysis results and theoretically by MEM analysis.
