Novel Ni-Ce-Zr/Al2O3 Cellular Structure for the Oxidative Dehydrogenation of Ethane
(MDPI, 2017-11)
A novel gamma-alumina-supported Ni-Ce-Zr catalyst with cellular structure was developed for oxidative dehydrogenation of ethane (ODHE). First, powdered samples were synthesized to study the effect of both the total metal ...
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 ...
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 ...

Electro-catalytic performance of 60%NiO/Ce0.9Zr0.1O2 cermets as anodes of intermediate temperature solid oxide fuel cells
(Elsevier, 2013-03-26)
This paper analyses the electrocatalytic performance of a 60%NiO/Ce0.9Zr0.1O2 anode under reducing atmospheres, using a symmetric cell configuration, [anode/electrolyte/anode], with Samaria doped Ceria (SDC) as electrolyte. ...
Ni-Cu/Ce0.9Zr0.1O2 bimetallic cermets for electrochemical and catalytic applications
(Elsevier, 2013-12)
The development of an economically feasible Solid Oxide Fuel Cell technology has driven the research activity in this area toward the reduction of their operating temperature. New anode materials, with high electrocatalytic ...
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, ...
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 ...
