Behavior of PtPb/MgAl2O4 catalysts with different Pb contents and trimetallic PtPbIn catalysts in n-butane dehydrogenation
(Elsevier, 2013-08)
The behavior of PtPb/MgAl2O4 catalysts in butenes production through the n-butane dehydrogenation has shown that at low contents, the Pb acts as promoter, improving the conversion and selectivity, whereas at higher contents ...
Effects of catalyst load in Pt and Pb-based catalysts using formic acid oxidation as a model
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In this paper, we discuss the effects of catalyst load with respect to carbon powder for several Pt and Pb-based catalysts, using formic acid as a model molecule. The discussion is based on electrochemical tests, a complete ...
Liquid-Phase Hydrogenation of Crotonaldehyde over Platinum- and Palladium-Based Catalysts
(American Chemical Society, 2009-12-26)
The selective hydrogenation of crotonaldehyde in liquid phase, at a temperature of 353 K and a H2 pressure of 400 kPa, is studied over different palladium- and platinum-based catalysts (Pd−Pb/α-Al2O3, Pd−Zn/α-Al2O3, Pd/ZnO, ...
Effect of the Synthesis Method of MgAl2O4 and of Sn and Pb Addition to Platinum Catalysts on the Behavior in n-Butane Dehydrogenation
(American Chemical Society, 2010-03)
The MgAl2O4 spinels, synthesized by using two different methods (ceramic and coprecipitation), show very low acidity and good dispersion capacity of the metallic phase, these properties being suitable for the use of these ...
Catalytic activity of Pt-Re-Pb/Al2O3 naphtha reforming catalysts

Highly selective and stable multimetallic catalysts for propane dehydrogenation
(John Wiley & Sons Ltd, 2000-07)
Different mono (Pt), bi (Pt–Sn, Pt–Pb, Pt–Ga) and trimetallic (Pt–Sn–Ga) catalysts based on Pt and supported on different materials (Al2O3, Al2O3–K and ZnAl2O4) were tested under severe process conditions in the propane ...
The influence of different co-catalysts in Pt-based ternary and quaternary electro-catalysts on the electro-oxidation of methanol and ethanol in acid media
(ELSEVIER SCIENCE SALAUSANNE, 2013-08-02)
One of the key objectives in fuel cell technology is to reduce Pt loading by the improvement of its catalytic activity towards alcohol oxidation. Here, a sol-gel based method was used to prepare ternary and quaternary ...
Synthesis, Characterization, and Electrocatalytic Activity toward Methanol Oxidation of Carbon-Supported Pt(x)-(RuO(2)-M)(1-x) Composite Ternary Catalysts (M = CeO(2), MoO(3), or PbO(x))
(AMER CHEMICAL SOC, 2010)
Carbon-supported platinum is commonly used as an anode electrocatalyst in low-temperature fuel cells fueled with methanol. The cost of Pt and the limited world supply are significant barriers for the widespread use of this ...
Carbon supported electrocatalysts prepared by the sol-gel method and their utilization for the oxidation of methanol in acid media
(SPRINGER, 2009)
One of the key objectives in fuel-cell technology is to improve the performance of the anode catalyst for the alcohol oxidation and reduce Pt loading. Here, we show the use of six different electrocatalysts synthesized by ...
