· Ce1 Sm1 O2

Ce₁Sm₁O₂ is a rare-earth mixed oxide ceramic compound combining cerium and samarium oxides, belonging to the family of lanthanide-based functional ceramics. This material is primarily of research interest for its ionic conductivity and redox properties, with potential applications in solid-oxide fuel cells (SOFCs), oxygen sensors, and catalytic systems where rare-earth dopants enhance performance in high-temperature electrochemical environments. The cerium-samarium combination is notable for tuning oxygen vacancy concentration and thermal stability compared to single-dopant or undoped ceria systems, making it relevant for engineers developing advanced energy conversion and gas-sensing devices.
