Ceria: Recent Results on Dopant-Induced Surface Phenomena

Inorganics, 2017
Redox studies on dense zirconia-doped ceria pellets were carried out by thermogravimetric investigations and dilatometry. Up to 1600 K reduction parameters determined by both methods correspond to each other.

Oxidation entropies and enthalpies of ceria–zirconia solid solutions

Catalysis Today, 2007
The thermodynamic redox properties for a series of ceria-zirconia solid solutions have been measured by determining their oxidation isotherms between 873 and 1073 K. Isotherms were obtained using Coulometric titration and using O2 titration of samples equilibrated in flowing mixtures of H2 and H2O. Samples having the following compositions were studied

Thermodynamic stability of doped ceria for solar reactors: Sublimation and surface segregation

Open Ceramics
The stability of ceria‑based redox oxides under high‑temperature solar‑thermal operation is crucial for fuel‑producing reactors. This study demonstrates that the gas pressure governs CeO2 sublimation from Gd0.1Ce0.9O1.95 (GDC-10) under solar ...

Development and performance evaluation of (Sm1-xNdx)0.2O2-δ electrolyte for low-temperature solid oxide fuel cell application

Energy Conversion and Management: X
Major hurdle for SOFC operation at lower temperature is it’s ion migration through electrolyte crystal lattice reduces as more energy required and lowered number of ion vacancies. In order, researchers from all over the world trying to develop SOFC which

Yttria and ceria doped zirconia thin films grown by pulsed laser deposition

Materials Research, 2013
The Yttria stabilized Zirconia (YSZ) is a standard electrolyte for solid oxide fuel cells (SOFCs), which are potential candidates for next generation portable and mobile power sources. YSZ electrolyte thin films having a cubic single phase allow reducing
