Application of Rare Earth Modified Zr-based Ceria-Zirconia Solid Solution in Three-Way Catalyst for Automotive Emission Control

open access: yes, 2016
Automotive exhaust emission is a major cause of air pollution. Three-way catalyst (TWC) which can eliminate CO, HC (hydrocarbons), and NOx simultaneously has been used to control exhaust emissions.

Space charge concept for acceptor-doped zirconia and ceria and experimental evidences

open access: yes, 2004
The grain boundary cores of acceptor-doped zirconia and ceria are positively charged. which is probably due to the oxygen, vacancy enrichment there. Oxygen vacancies are therefore depleted in the space charge layers.

Structure Of Ceria Overlayer On Zirconia Crystal Studied by Surface Diffraction

open access: yes, 1995
We have utilized white x-ray beam and a Ge solid state detector, in energy dispersive mode, to study the diffraction from the surface layers of ceria deposited on (001) surface of Y stabilized cubic zirconia with grazing incident beam.

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

open access: yesOpen 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

open access: yesEnergy 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
