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 ...
New Formulations of Ni-Containing Ceramic Papers to Enhance the Catalytic Performance for the Oxidative Dehydrogenation of Ethane
(American Chemical Society, 2014-10)
Ceramic papers composed of silica–alumina fibers structured using colloidal suspensions as binders constitute interesting materials to be used as flexible supports of catalytic materials. The deposition of Ni as the active ...
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 ...

Propriedades eletrônicas e estruturais do Cu/ZrO2 aplicadas à reação do etanol
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2012-06-22)
Copper is a typical catalyst for dehydrogenation of ethanol to acetaldehyde. However, copper supported on ZrO2 was found to be extremely active and selective to convert ethanol directly to ethyl acetate. Several reports ...
Potassium-promoted Ce0.65Zr0.35O2 monolithic catalysts for diesel soot combustion
(Elsevier, 2014-03)
This work presents a comparative study of Ce0.65Zr0.35O2 and CeO2 catalysts supported on cordierite for soot combustion, and the effect of potassium on the catalytic performance. The catalysts were prepared by sequential ...

Catalytic oxidation of sulfur compounds over Ce-SBA-15 and Ce-Zr-SBA-15
(Elsevier Science, 2021-01)
The catalytic oxidation of different sulfur compounds, commonly present in liquid fuel, was studied over a series of ceria and ceria-zirconium based oxidation mesoporous catalysts. SBA-15 was synthesized using sol-gel ...
Catalisadores de Au/ZrO2 e Au/In2O3/ZrO2: Efeito das propriedades eletrônicas e estruturais na atividade para desidrogenação do etanol e hidrogenação de CO2
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-10-28)
Au/ZrO2 and Au/In2O3/ZrO2 catalysts were developed for CO2 hydrogenation reaction and Au/ZrO2 for ethanol dehydrogenation. The monometallic gold catalysts supported on ZrO2 with different contents (0.3 to 5.0%w/w) were ...
