Pt–Pd/C bimetallic catalysts with low platinum contents were synthesized by surface redox reactions. In this method, hydrogen preadsorbed on the palladium surface of the parent catalyst (Pd/C) acts as a reducer of the PtCl 6 − species, allowing a

The role of TiO2 as an additive in the Pt/WO3-ZrO2 catalyst system over the catalytic activity in the hydroisomerization of n-hexane was investigated. The Pt/WO3-ZrO2-TiO2 catalysts were synthesized by two steps: the first step consisted in the WOx-Z

The trends in the development of acid catalysts for isomerization show that the diffusion and accessibility of products are more favored in mesoporous as compared to microporous materials. In this work, an easy metal alkoxide- and surfactant-free tec

Tungstated zirconia catalysts promoted with different contents of Fe and Mn (ZWFM) were synthesized by the coprecipitation method. The materials were characterized by XRD, Raman, XPS, and HAADF-STEM. Platinum was added by impregnation and reduced in

New Bi2Se3/BiOCl composites were synthesized with a p-n heterojunction by two different synthesis methods: coprecipitation and hydrothermal. Likewise, some synthesis parameters were modified such as the chelating agent concentration (EDTA) and the sy

Alumina (Al2O3) and Alumina-Ceria (Al2O3-CeO2) supports with different CeO2 loadings (0, 2, 5, 10 and 50 wt.%) were prepared by the sol-gel method and impregnated with 0.5% of Pt and 0.5 % of Pd (wt.%). The catalysts were characterized by X-ray diffr

The oxidation of methanol was carried out on platinum nanoparticles supported on carbon Vulcan (10 wt % Pt/C), as well as on the tungsten-oxide-modified material (Pt/WO3–C; WO3 5 wt %). The Pt/C samples were synthesized by the impregnation method,
