Redox behaviour of a ceria–zirconia inverse model catalyst [PDF]

, 2019
The redox behaviour modification following the addition of zirconia to ceria nanostructures supported on Rh(111) has been investigated using a combination of Low Energy Electron Diffraction (LEED) and X-ray Photoemission Electron Microscopy (XPEEM). Soft

Tribology and in-vitro biological characterization of TiO2 addition on ceria stabilized zirconia-toughened alumina (CSZTA) composite

Journal of Asian Ceramic Societies, 2023
The effect of TiO2 addition on tribology and in-vitro biological characteristics of ceria-stabilized zirconia-toughened alumina (CSZTA-TiO2) ceramic composites were examined and presented in this study. Through the powder metallurgy route, the TiO2 added

Influence of doping of ceria and scandia on the point defects of zirconia based material

上海师范大学学报. 自然科学版, 2017
The advanced properties of rare-earth oxide doped zirconia materials are closely related to the different types of point defects which exist in zirconia crystals.These point defects are mainly in the form of oxygen vacancies.The research sample is ...

Mechanical properties of partially stabilized zirconia for dental applications

Journal of Asian Ceramic Societies, 2019
In esthetic dental care, porcelain-fused-to-metal crowns have long been used for dental restoration. Since a dental prosthesis is placed in the harsh environment of the oral cavity over long periods, metal allergy due to eluate from the metal frame has ...

Enhanced Activity and Stability of Gold/Ceria-Titania for the Low-Temperature Water-Gas Shift Reaction

Frontiers in Chemistry, 2019
Gold supported on ceria-zirconia is one of the most active low temperature water-gas shift catalysts reported to date but rapid deactivation occurs under reaction conditions.

Influence of Nanoscale Surface Arrangements on the Oxygen Transfer Ability of Ceria–Zirconia Mixed Oxide

Inorganics, 2020
Ceria-based materials, and particularly CeO2–ZrO2 (CZ) solid solutions are key ingredient in catalyst formulations for several applications due to the ability of ceria to easily cycling its oxidation state between Ce4+ and Ce3+.
