Productivity and order versus the superficial behavior of the prox reaction on a copper-ceria catalyst Monte Carlo simulations
(Elsevier, 2016)
Monte Carlo simulations for the productivity and order of the PROX/copper-ceria catalyst reaction with different superficial %Cu are made. The results are correlated with the behavior of the different surface species (CO, ...
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 ...
Estudo de catalisadores de cobre suportados para a reação de oxidação preferencial do CO
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2010-06-30)
The CO preferential oxidation reaction (PROX-CO) has been widely studied in last few years. Aiming H2 purification for proton-exchange membrane cells (PEMFC) use, the main role of the PROX-CO reaction should be reduce the ...
Catalisadores de Au suportados aplicados à oxidação preferencial do CO : influência da interação entre Au e Fe nos sítios ativos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-04-07)
New sources of clean energy have been studied, such as hydrogen (H2). Carbon monoxide, a subproduct of its production, poisons the fuel cell. To reach concentrations below 10 ppm, the addition of preferential CO oxidation ...

Estudo de catalisadores bimetálicos de platina ou paládio e cobre suportados em céria para a reação de PROX-CO
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-10-13)
In the present work, catalysts were prepared xCuO / CeO2 (x = 1.0 and 3.0% by mass)
doped with Pt or Pd for application in the preferred oxidation reaction of carbon
monoxide, also known as PROX-CO reaction. The catalysts, ...
CuO-CeO2 catalysts synthesized in one-step: Characterization and PROX performance
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
PEM fuel cells seem to be the most affordable and commercially viable hydrogen-based cells, the biggest challenge being to obtain CO-free H-2 (<100 ppm) as the fuel. In this study, the use of CuO-CeO2 catalysts in ...
CO Total and preferential oxidation over stable Au/TiO2 catalysts derived from preformed au nanoparticles
(Molecular Diversity Preservation International, 2020-09-07)
CO preferential oxidation (PROX) is an effective method to clean reformate H2 streams to feed low-temperature fuel cells. In this work, the PROX and CO oxidation reactions were studied on preformed Au nanoparticles (NPs) ...
Effect of Pt-MOx (M = Fe, Co) interaction on the preferential oxidation of CO over Pt/MOx/TiO2 catalysts prepared by selective electrostatic adsorption
(Elsevier B.V., 2019)
In this work, the catalytic properties of Pt/MOx/TiO2 (M = Fe, Co) catalysts prepared by strong electrostatic adsorption (SEA), were investigated for the preferential oxidation (PROX) of CO in H2. The SEA method was chosen ...
