Dependence on composition of electronic properties and stability of Pt-Fe/C catalysts for oxygen reduction
(Elsevier B.V., 2010-11-01)
This work presents studies of electronic characteristics and alloy stability carried out for Pt-Fe/C catalysts of different compositions (10-50% Fe, in atoms) and same particle size. The electronic properties are characterized ...
Influence of Pt addition to Ni catalysts on the catalytic performance for long term dry reforming of methane
(Elsevier Science, 2012-09)
The influence of Pt addition (in very low concentrations) to a Ni/(10%)/Al 2O 3 catalyst in its catalytic performance during long-term experiments of dry reforming of methane was studied. The monometallic Pt(0.5%)/Al 2O 3 ...
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, ...
Understanding the stability of Co-supported catalysts during ethanol reforming as addressed by in situ temperature and spatial resolved XAFS analysis

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 ...
Pt-Co and Pt-Ni Catalysts of Low Metal Content for H2 Production by Reforming of Oxygenated Hydrocarbons and Comparison with Reported Pt-Based Catalysts
(Hindawi Limited, 2018-07)
New catalysts of Pt, PtNi, PtCo, and NiCo supported on Al2O3 were developed for producing hydrogen by aqueous phase reforming (APR) of oxygenated hydrocarbons. The urea matrix combustion technique was used for loading the ...
Selective liquid-phase hydrogenation of citral over supported bimetallic Pt-Co catalysts
(Elsevier Science, 2009-04)
The liquid-phase hydrogenation of citral was studied at 393 K and 10 bar on Pt-Co/C catalysts, having different Pt/(Pt+Co) ratios and containing a total metal loading of about 2%. The monometallic and bimetallic Pt-Co/C ...
Study of Pt and Rh based supported catalysts modified with tetrabutyltin for the selective hydrogenation of 4-methoxyacetophenone
(Springer, 2007-10)
Catalysts based on Pt and Rh modified with Sn(C4H 9)4 were studied in the hydrogenation of 4-methoxyacetophenone. The selectivity to 1-(4-methoxyphenyl)ethanol was close to 100% at Sn/(Pt,Rh) = 1.0, however the catalytic ...
