Síntesis y caracterización de catalizadores de Co-Ni-Ce/TiO2 y Ni-Ce/SiO2 para la descomposición catalítica de CH4
(Primer coloquio sobre “Propiedades Fisicoquímicas de Sistemas Complejos Nanoestructurados (pFisiconano2011)”, 2013-01-16)
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 ...
Estudo de catalisadores a base de Ni, Pd e Ce suportados em MCM-41 na oxidação parcial do metano
(Instituto de QuímicaPrograma de Pós Graduação em QuímicaIQbrasil, 2016-09-08)
A oxidação parcial do metano foi estudada sobre catalisadores Ni/MCM-41
modificados ou promovidos com Ce ou Pd. Foram sintetizados catalisadores Ni/MCM-
41 nos teores 5%, 10% e 20% de Ni, além das amostras Pd/MCM-41, ...
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 ...
Catalisadores de Ni suportados em óxidos sintetizados com líquido iônico: atividade catalítica na tri-reforma do metano
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-04-11)
Tri-reforming reaction is a new method to use and convert CO2 from industrial plants effluents. The tri-reforming involved reactions are two endothermic reactions, the steam and dry reforming and the partial methane oxidation ...
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 ...
Electrochemical performance of Ni-RE (RE = rare earth) as electrode material for hydrogen evolution reaction in alkaline medium
(International Journal of Hydrogen Energy Volume 36, Issue 1, January 2011, Pages 135-151, 2011-01-01)
In this work, Ni-RE (RE = rare earth, La, Ce) materials were obtained by the solid state reaction using as Ni source: a) metal acetylacetonates and b) metal powders while rare earth element was added from acetylacetonates. ...
CO preferential oxidation (CO-PROx) on La(1-x)Ce(x)NiO(3) perovskites
(ELSEVIER SCIENCE BV, 2011)
La(1-x)Ce(x)NiO(3) perovskites have been prepared, characterized by XRD. TPR and surface area and tested as catalysts for CO-PROx, with a feed of 2.5% CO, 5% O(2), 33% H(2) and N(2) to 100%. The samples exhibited an XRD ...
