Pd-based binary and ternary alloy membranes: Morphological and perm-selective characterization in the presence of H2S
(Elsevier, 2013-09)
Pd, Pd90Ag10, Pd91Au9, Pd78Ag9Au13 and Pd75Ag16Au9 alloy membranes were prepared on vacuum-assisted ZrO2-modified porous stainless steel supports by sequential electroless deposition. The membranes were evaluated for ...
Glycerol oxidation reaction using PdAu/C electrocatalysts
(2016-07-01)
Glycerol oxidation reactions were evaluated using PdAu/C electrocatalysts under alkaline conditions. These electrocatalysts were synthesized in different ratios (100:0, 75:25, 50:50, 25:75, and 0:100), using the borohydride ...
Estudo da adsorção e oxidação do monóxido de carbono sobre as fases intermetálicas ordenadas AuIn, AuSb2, AuSn, PdSb e PdSn
(Universidade Estadual Paulista (Unesp), 2009)
Aiming to reduce the cost of electrocatalysts and a greater resistance to CO poisoning this work was to study the adsorption and oxidation of carbon monoxide on ordered intermetallic phases AuIn, AuSb2, AuSn, PdSb and PdSn ...
Hydrogen permeation and surface properties of PdAu and PdAgAu membranes in the presence of CO, CO2 and H2S
(Elsevier Science, 2018-10-01)
Using the electroless deposition technique with different deposition sequences, it was possible to obtain a single phase PdAgAu ternary alloy after treatment at 773 K during 7 days. Despite the order of deposition, the ...
Influencia de los soportes en la actividad catalítica de nanopartículas de Pd y Au-Pd corazón-envolvente en la electrooxidación del metanol
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. Coordinación de Servicios de Información., 2017-02)
En el presente trabajo, catalizadores de Pd (20% en peso de carga de metal) fueron sintetizados y soportados en carbón Vulcan XC72R (C), polvo de diamante (DP, Diamond Powder) y óxido de titanio (TiO2). Los catalizadores ...
Theoretical Study of Hydrogen Adsorption on Au@Pd Icosahedral Nanoparticle
(American Chemical Society, 2017-04-06)
First-principles calculations based on the density functional theory (DFT) were applied to study the H2 adsorption on Au@Pd NP (core@shell icosahedral bimetallic nanoparticle). The calculations indicate that, for almost ...
Biosíntesis y caracterización de nanopartículas bimetálicas de oro-paladio usando extracto de Tamarix gallica para aplicaciones fotocatalíticas
(Universidad Michoacana de San Nicolás de Hidalgo, 2017-06)
In this work, golden (NpsAu) and palladium (NpsPd) nanoparticles were synthesized, as well as bimetallic gold-palladium (NpsAu-Pd) core-shell type at room temperature, using the aqueous extract of leaves and stem of the ...
What Determines Electrochemical Surface Processes on Carbon Supported PdAu Nanoparticles?
(Amer Chemical Soc, 2018-03-01)
Supported bimetallic nanoparticles have good activities in heterogeneous catalysis and electrocatalysts. Among those systems, PdAu shows improved stability and enhanced catalytic activity toward electrochemical reactions ...
