A new activation process of bimetallic catalysts and application to the n-hexane isomerization
(Elsevier Science, 2009-02)
Bimetallic catalysts applied to the n-hexane isomerization reaction were prepared with a constant molar content of 130 μmol Me/gcat of Ni and Pt and characterized in its active form by X-ray absorption near edge spectroscopy ...
Supported Pt and Pt-Ru catalysts prepared by potentiostatic electrodeposition for methanol electrooxidation
(Springer, 2008-04)
Methanol electrooxidation was investigated on Pt-Ru electrocatalysts supported on glassy carbon. The catalysts were prepared by electrodeposition from solutions containing chloroplatinic acid and ruthenium chloride. Bulk ...
Keggin heteropolyacids Mo-based as catalysts in the green and selective oxidation of diphenyl sulfide
(Elsevier, 2013-03)
Heteropolyacids are used as redox catalysts due to their bifunctional properties. Some advantages over conventional catalysts, such as selectivity, easy isolation and reuse, are worth noting. In homogeneous conditions their ...
Ethylbenzene production over platinum catalysts supported on modified KY zeolites
(2010)
Platinum catalysts supported on zeolite KY (Si/Al = 12.7), modified with magnesium, calcium or barium,were evaluated in n-octane reforming to produce ethylbenzene. The catalysts were characterized by nitrogen adsorption, ...
n‐octane reforming over alumina‐supported Pt, Pt–Sn and Pt–W catalysts
(2000)
Pt, Pt–Sn and Pt–W supported on γ‐Al2O3 were prepared and characterized by H2 chemisorption, TEM, TPR, test reactions of n‐C8 reforming (500°C), cyclohexane dehydrogenation (315°C) and n‐C5 isomerization (500°C), and TPO ...
Valorization of Different Wastes and Their Use for the Design of Multifunctional Eco-catalysts
(Springer, 2016-07-25)
The desire to protect the environment for futuregenerations has led to the reutilization of all recoverableand recyclable wastes. Consequently, different residuesfrom various sources were collected to make mixed compoundsto ...
Sulfur Poisoning of Bi- and Trimetallic ç-Al2O3-Supported Pt, Re, and Sn Catalysts
(2004)
Bifunctional metal/acid catalysts with Pt, Pt−Re, Pt−Sn, and Pt−Re−Sn as metallic functions supported on chlorided γ-alumina were prepared by successive impregnation or by coimpregnation of aqueous solutions of the metal ...
Acidic V-MCM-41 catalysts for the liquid-phase ketalization of glycerol with acetone
(2019-01-01)
SiMCM-41 and V-MCM-41 were hydrothermally synthesized with different quantities of vanadium, characterized by small angle X-ray scattering, nitrogen physisorption, and the insertion of vanadium was assessed by temperatur ...
Highly selective synthesis of menthols from citral in a one-step process
(Elsevier Science, 2004-06)
We report for the first time the selective synthesis of menthols from citral in a one-step process. Bifunctional metal/acid catalysts active and selective for menthol synthesis were developed by studying the individual ...
