Inverse opal ceria–zirconia: architectural engineering for heterogeneous catalysis [PDF]

, 2008
The application of inverse opal structured materials is extended to the ceria–zirconia (Ce_(0.5)Zr_(0.5)O_2) system and the significance of material architecture on heterogeneous catalysis, specifically, chemical oxidation, is ...

Alumina supported Pt(1%)/Ce0.6Zr0.4O2 monolith: Remarkable stabilization of ceria–zirconia solution towards CeAlO3 formation operated by Pt under redox conditions

, 2009
A structured Pt(1 wt%)/ceria–zirconia/alumina catalyst and the metal-free ceria–zirconia/alumina were prepared, by dip-coating, over a cordierite monolithic support.

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 ...

Methane dry reforming over ceria-zirconia supported Ni catalysts

, 2016
Nickel nanoparticles supported on Ce1-xZrxO2 mixed oxides prepared by different synthesis methods, as well as Ni-ZrO2 and Ni-CeO2, were evaluated for their catalytic performance in methane dry reforming (MDR).

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

Interfacial Structure and Point Defects in Ceria/Zirconia Superlattices

, 2006
We report the results of a molecular dynamics simulation study aiming to understand the interfacial structure in ceria/zirconia superlattices and the impact of the interfaces on the energies of oxygen vacancy formation and Gd ion substitution in ceria ...

Performance degradation and recovery of YSZ membrane under sulphuric acid thermal decomposition [PDF]

, 2013
The effect of sulphur dioxide (SO2) present in the cathode feed stream on the performance of a 8 mole% yttria-stabilized zirconia/platinum (8YSZ/Pt) cell was studied. SO2 concentration of 30% in oxygen (5ml/min) and helium (30ml/min) was exposed to

Infrared confocal imaging for inspection of flaws in yttria-stabilized tetragonal zirconia polycrystal (Y-TZP)

, 2011
Custom made medical yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) components require a high standard of machining and inspection techniques to ensure high reliability of the manufactured parts. Due to heat generated during machining processes,
