The role of the coprecipitation sequence of salt precursors on the genesis of Cu-ZnO-Al2O3 catalysts. synthesis, characterization and activity for low temperature shift reaction
(1998-06)
Cu-ZnO-Al2O3 catalysts for the low-temperature water-gas shift reaction were prepared using methods of direct and reverse coprecipitation. The catalysts obtained were characterized by DRX, TPR, XPS, N2O chemisorption, ...
Towards a rational design of enantioselective heterogeneous catalysts: Modeling of chiral organotin precursors
(Elsevier Science, 2010-08)
In this work, the modeling of organotin compounds of general formula Men-Sn-R3 (Men=menthyl, R=alkyl or alkoxyalkyl) is carried out. These compounds can be employed as precursors for obtaining enantioselective heterogeneous ...
Methane combustion over PdO-alumina catalysts: The effect of palladium precursors
(2006)
The role of palladium precursors and the preparation route in the catalytic properties of PdO/Al2O3 catalysts toward methane oxidation was investigated in this paper. The catalysts were prepared using palladium chloride, ...
Cobalt catalysts derived from hydrotalcite-type precursors applied to steam reforming of ethanol
(ELSEVIER SCIENCE BV, 2011)
Catalysts derived from Co/Mg/Al hydrotalcite-type precursors modified with La and Ce were characterized by XANES and tested in ethanol steam reforming. The reaction data showed that, with a molar ratio of water: ethanol = ...
Effects of adding La and Ce to hydrotalcite-type Ni/Mg/Al catalyst precursors on ethanol steam reforming reactions
(ELSEVIER SCIENCE BV, 2010)
Catalyst precursors composed of Ni/Mg/Al oxides with added La and Ce were tested in ethanol steam reforming (ESR) reactions. La and Ce were added by anion-exchange. The oxides were characterized by X-ray photoelectron ...
Pt-Re-Ge/Al 2O 3 catalysts for n-octane reforming: Influence of the order of addition of the metal precursors
(Elsevier Science, 2012-03)
Trimetallic Pt-Re-Ge supported catalysts for naphtha reforming were prepared by successive impregnation of suitable precursors on gamma alumina. The order of addition of these precursors was varied and its influence on the ...
Pt–Re–Ge/Al2O3 catalysts for n-octane reforming: Influence of the order of addition of the metal precursors
(2012)
Trimetallic Pt–Re–Ge supported catalysts for naphtha reforming were prepared by successive impregnation of suitable precursors on gamma alumina. The order of addition of these precursors was varied and its influence on the ...
Ni-supported catalysts for ethanol steam reforming: effect of the solvent and metallic precursor in catalyst preparation
(Springer, 2017-12)
Ethanol steam reforming was studied over Ni/MgAl2O4–CeO2 catalysts. The catalysts were prepared using different impregnation media (ethanol or water) and Ni precursors (nitrate or acetate). The use of an alcoholic solution ...
