A first-principles modeling of Ni interactions on CeO2-ZrO 2 mixed oxide solid solutions
(American Chemical Society, 2011-04)
We performed DFT+U quantum period calculations to study the characteristics of Ni interactions on/in CeO2-ZrO2 mixed oxide solid solutions. We analyzed the energetics of Ni adsorption and insertion on/in different surface ...
AC impedance study of Ni, Fe, Cu, Mn doped ceria stabilized zirconia ceramics
(Elsevier B.V., 2001-09-01)
Doped zirconia has been used in electronic applications in the cubic crystalline phase. Ceria-stabilized tetragonal zirconia presents high toughness and can also be applied as solid electrolytes. The tetragonal phase of ...

Ni catalyst on mixed support of CeO2-ZrO2 and Al2O3: Effect of composition of CeO2-ZrO2 solid solution on the methane steam reforming reaction
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this study, catalysts containing 5 wt.% Ni deposited on a support composed of a CeO2-ZrO2 solid solution deposited on alumina were tested in the steam reforming of methane. The supports, with various ratios of Ce to Zr, ...
Structural and reduction studies of ZrO2-CeO2:Ni for application in SOFC anodes.
(Vellidis Congress CenterTessaloniki, 2013-07-09)
Zirconia-ceria solid-solutions are extensively used as promoters for three-way catalysts, which are applied in the control of NOx, CO and hydrocarbons emission from automotive exhausts. In addition, thesematerials can be ...
In-situ XANES experiments on Ni K-edge in mesoporous ZrO2-CeO2:Ni.
(Campinas, 2014-03-06)
Ordered mesoporous ZrO2-CeO2 mixed oxides are potential candidates for catalytic applications. These systems, used as anodes in solid oxide fuel cells (SOFC), may lead to better performance of SOFCs, due to an enhancement ...
Synthesis and characterization of mesoporous NiO2/ZrO2-CeO2 catalysts for total methane conversion
(Elsevier, 2017-07)
This work reports the synthesis and characterization of mesoporous NiO/ZrO2-CeO2 composites. These materials are still being developed due to their excellent morphological and structural properties, especially for solid ...
In situ X-ray absorption spectroscopy study of CuO-NiO/CeO2-ZrO2 oxides: redox characterization and its effect in catalytic performance for partial oxidation of methane
(Royal Soc Chemistry, 2018)
In this work we analyze the effect of adding CuO to a NiO/Ce0.9Zr0.1O2 oxide by in situ X-ray absorption near-edge structure XANES technique in Ce L3, Ni K and Cu K absorption edges in terms of sample reducibility and ...
Catalisadores de Fe2O3, NiO e Fe2O3 - NiO Suportados in situ em Ce0,5Zr0,5O2 e Ce0,2Zr0,8O2 – Avaliação na Redução de NO com CO
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2014-03-28)
The increasing use of fossil fuels in combustion enginees and power generation plants
has caused a large increase in the emission of sulfur oxides, nitrogen oxides (NOx)
and carbon monoxide into the atmosphere which ...
