Bimetallic PtSn catalyst for the selective hydrogenation of furfural to furfuryl alcohol in liquid phase
(Elsevier Science, 2009-05-20)
Bimetallic PtSn catalysts, containing different amounts of tin, were obtained by means of controlled surface reactions and used in the liquid-phase hydrogenation of furfural. All the studied systems allowed to obtain fufuryl ...

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 ...
Influence of pretreatment atmospheres on the performance of bimetallic Au-Pd supported on ceria-zirconia mixed oxide catalysts for benzyl alcohol oxidation
(Elsevier Science, 2016-09)
Monometallic Au, Pd and bimetallic Au-Pd catalysts supported on a Ce0.62Zr0.38O2mixed oxide have been synthesized by the sol-immobilization method. The catalysts have been characterized by inductively coupled plasma-atomic ...
Support effect over bimetallic ruthenium-promoter catalysts in hydrogenation reactions
(Elsevier Science SaLausanneSuíça, 2010)
Effect of the sequence of impregnation on the activity and sulfur resistance of PtNi/-Al2O3 bimetallic catalysts for the selective hydrogenation of styrene
(Elsevier Science, 2012-06)
The influence of the preparation of bimetallic Pt–Ni catalysts on their activity and sulfur resistance during styrene semi-hydrogenation was studied. The preparation variables assessed were the sequence of impregnation and ...
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 ...
Bimetallic catalysts supported on novel spherical MgAl2O4-coated supports for dehydrogenation processes
(Elsevier Science, 2018-10)
Novel Pt and PtSn catalysts were developed from structured supports of α-Al2O3 spheres coated with MgAl2O4 by two methods: advanced Bohemite-nitrate with purification (BNAP) and citrate-nitrate with two layers (CN2). Both ...
