Carbon dioxide reforming of methane (CDRM) was studied over a variety of ZrO2-, ceria-doped ZrO2-, and CeO2–ZrO2-supported Ni catalysts. Different techniques were used to prepare supports material having different physicochemical properties, and a correlation was established to show the importance of a robust support material.

Kinetics of hydrogen activation on ceria–zirconia
Journal of Catalysis, 2015Abstract Ceria–zirconias are popular catalysts and supports for metal particles. Even without supported metal particles, these materials are active for hydrogenation and hydrodeoxygenation reactions, where oxygen vacancies serve as the active site.

Mechanical properties in the ceria-zirconia system
Journal of the European Ceramic Society, 1992Abstract The room temperature mechanical properties of samples ranging through the whole zirconia-ceria system have been determined and related to the phases present in order to establish the influence of crystallographic parameters on the material properties.

Redox Behaviour of a Ceria Zirconia Alloy
1989The thermal history of ceria zirconia solid solutions greatly influences their structure and properties, particularly their electric conductivity. This in turn depends on a reversible redox reaction here investigated by means of TG, DTA and TDM measurements.

Ceria-zirconia Nanocatalysts for Diesel Soot Combustion
SAE Technical Paper Series, 2015<div class="section abstract"><div class="htmlview paragraph">A set of ceria-zirconia nanocatalysts with different Zr-contents and structural properties was prepared to study the effect of both the Zr-amount and surface-dependent activity towards soot combustion in “loose” and “tight” soot-catalyst contact.

Advanced Electron Microscopy Investigation of Ceria–Zirconia‐Based Catalysts
ChemCatChem, 2010AbstractThe potentials of advanced transmission and scanning transmission electron microscopy in nanostructural studies of ceria–zirconia mixed oxides are overviewed. The crystallographic criteria that allow us to discriminate the different CeO2–ZrO2 polymorphs and the nanocrystal size range within which they can be applied are discussed.

Ceria–zirconia based catalysts for ethanol steam reforming
Fuel, 2015Abstract Mixed ceria–zirconia oxide (CZ91, Ce:Zr = 9:1) has been used to support Nickel (CZ91Ni), Cobalt (CZ91Co) and bimetallic Nickel/Cobalt active phases (CZ91NiCo) to be tested in Ethanol Steam Reforming reaction (ESR). H 2 -TPR analyses and IR studies of adsorbed probe molecules suggest that ceria/zirconia actually favors the reduction of ...

Thermally induced changes in the ceria zirconia system
Thermochimica Acta, 1988Abstract The redox behaviour of ceria zirconia alloy (50 mol %) has been investigated by thermoanalytical methods under controlled atmospheres (air, oxygen and argon with 5% hydrogen). The supposed non-stoichiometry (CeOx-ZrO2, x being a function of oxygen pressure and temperature) is proved by weight changes which are accompanied by volume ...
