Influence of additives on the Pt metal activity of naphtha reforming catalysts
(Elsevier Science, 2009-02)
Alumina supported bimetallic Pt-Re, Pt-Sn and Pt-Ge naphtha reforming catalysts were studied. The Pt concentration was kept constant at 0.3% (weight basis) while the concentration of the second metal was varied in order ...
Research on methanol-tolerant catalysts for the oxygen reduction reaction
(Springer, 2015-06)
Direct methanol fuel cells (DMFCs) generate electricity in a clean and efficient way, so they are a valuable alternative to traditional environmentally harmful technologies. Portable power sources are one of the applications ...
Ga and In promoters in bimetallic Pt based catalysts to improve the performance in the selective hydrogenation of citral
(Elsevier Science, 2015-05)
In this paper, bimetallic PtGa and PtIn catalysts supported on multiwall carbon nanotubes and carbon Vulcan were used to study the hydrogenation of citral (alpha,beta-unsaturated aldehyde) in liquid phase to produce nerol ...
PREPARATION OF CHIRAL ORGANIC-INORGANIC SOLID HYBRIDS: USE AS SUPPORT OF CATALYSTS IN THE ENANTIOSELECTIVE HYDROGENATION OF ETHYL PYRUVATE

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 ...
Sulfur Resistance of Pt-W catalyst
(Hindawi Publishing Corporation, 2013-01)
The sulfur resistance of low-loaded monometallic Pt catalysts and bimetallic Pt-W catalysts during the partial selective hydrogenation of styrene, a model compound of PYGAS streams, was studied. The effect of metal ...
Study of the performance of Pt catalysts supported on activated carbon felt and granular carbon for nitrobenzene hydrogenation
(Elsevier Science SA, 2005-11)
The catalytic behavior of the Pt (1 wt%) catalysts supported on purified activated carbon felt (ACF) and powder carbon (C) has been studied in the nitrobenzene (NBZ) hydrogenation reaction in liquid phase after activation ...
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 ...
Ru‐Pt catalysts supported on Al2O3 and SiO2─Al2O3 for the selective ring opening of naphthenes
(Wiley, 2019-11)
Alumina and silica-alumina supported Ru-Pt catalysts were evaluated for the ring opening of naphthenes. Pt, Ru and Ru-Pt catalysts were prepared by impregnation of inorganic precursors over γ-alumina and silica-alumina ...
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 ...
