General description

Cerium(IV) oxide-samarium doped nanopowder (15% mol samarium doped) (SDC) is an electrolytic material with a high oxygen ion conductivity. Samarium ion acts as an aliovalent cation that can be incorporated into the host lattice to increase the oxygen vacancy concentration and improve the oxide ion conduction in cerium oxide. It can be synthesized by reverse strike co-precipitation technique.
Samarium doped ceria may be used as an electrolyte in solid oxide fuel cells (SOFCs). Electrical conductivity as a function of temperature of doped ceria was investigated in a study. Relation of dopant type, oxygen vacancy ordering and ionic conductivity was investigated by transmission electron microscopy and electron energy loss spectroscopy.

Application

Cerium(IV) oxide-samarium doped can be used in the fabrication of solid oxide fuel cells (SOFCs), which can further be used as environmentally-friendly sources of alternative energy.
