CuO and CeO2 catalysts supported on Al2O3, ZrO2, and SiO2 in the oxidation of CO at low temperature
(ELSEVIER, 2008-07-01)
The effect of the support, Al2O3, ZrO2, and SiO2, on the activity for CO oxidation of a series of CuO and CeO2 monometallic and bimetallic catalysts was studied. The catalysts were prepared by coimpregnation of the support ...
Hydrogen Production by Steam Reforming of Ethanol on Rh-Pt Catalysts: Influence of CeO2, ZrO2, and La2O3 as Supports
(Catalysts, 2015-11-11)
CeO2-, ZrO2-, and La2O3-supported Rh-Pt catalysts were tested to assess their ability to catalyze the steam reforming of ethanol (SRE) for H2 production. SRE activity tests were performed using EtOH:H2O:N2 (molar ratio ...
Use of PdCu catalysts supported on zirconia-ceria based supports for the elimination of oxyanions present in water
(Elsevier Science, 2021-07-15)
In the present work, the elimination of NO3-, NO2- and BrO3- in distilled and groundwater samples using H2 as reducing agent is studied. For this purpose, PdCu-based catalysts were prepared on CeO2 pure and modified with ...
Synthesis of PtSn nanostructured catalysts supported over TiO2 and Ce-doped TiO2 particles for the electro-oxidation of ethanol
(Elsevier Science, 2016-09)
PtSn/TiO2 and PtSn/Ce-doped TiO2 catalysts were synthesized and evaluated for ethanol electro-oxidation in acid media. Titanium dioxide and Ce-doped TiO2 nanoparticles were prepared by hydrothermal method followed by ...
Hydrogen purification for fuel cell using CuO/CeO(2)-Al(2)O(3) catalyst
(ELSEVIER SCIENCE BV, 2011)
CuO/CeO(2), CuO/Al(2)O(3) and CuO/CeO(2)-Al(2)O(3) catalysts, with CuO loading varying from 1 to 5 wt.%, were prepared by the citrate method and applied to the preferential oxidation of carbon monoxide in a reaction medium ...
Study of the influence of the Cu/Ce loading ratio in the formation of highly active species on ZrO2 supported copper-ceria catalysts
(Elsevier Ltd, 2019)
© 2018 Elsevier B.V. This work studies the effect of different Cu/Ce loading ratios in the formation of highly dispersed copper species being interacting with CeO2 on zirconia-supported CuO–CeO2 catalysts. These species ...
A comparative investigation of metal-support interactions on the catalytic activity of Pt nanoparticles for ethanol oxidation in alkaline medium
(2016-04-15)
The effects of interactions of Pt nanoparticles with hybrid supports on reactivity towards ethanol oxidation in alkaline solution are investigated. Studies involve catalysts with identical Pt nanoparticles on six hybrid ...
Cobalt based catalysts for CO Preferential Oxidation
(IntechOpen, 2019)
In this work, catalysts based oncobalt supported on ZrO2 and CeO2, and CoCeMnOx were studiedfor the CO preferential oxidation (COPrOx) in rich-hydrogen stream able to feedfuel cells. Among them, the CoCeMnOx formulation ...
