钆掺杂的氧化铈(IV)，Cerium(IV) oxide-gadolinium doped；nanopowder, contains 20 mol % gadolinium as dopant

Cerium(IV) oxide-gadolinium doped nanopowder (20 mol% gadolinium doped) is an electrolytic material with a high oxygen-ion conductivity, which operates at low temperatures. It can be prepared by a variety of methods such as sol-gel, wet chemical process, co-precipitation, hydrothermal and other combustion routes.[1][2]

Gadolinium doped ceria may be prepared by cation complexation sol gel technique. XRD, specific surface area, morphology has been described in a study.[2] Higher oxygen ion conductivity of GDC over zirconia based materials makes it a preferable choice for some components of SOFCs.[3]

Gadolinium doped ceria (GDC) may be used as an intermediate temperature electrolyte for solid oxide fuel cells (SOFCs) at elevated temperatures.[4][2]
