[EN] Nitroderivatives are transformed to cyclohexylanilines at room temperature in good yields and selectivity via a hydrogenation-amine coupling cascade reaction using Pd nanoparticles on carbon as a catalyst and a Bronsted acid.

[EN] A series of organic-inorganic hybrid bifunctional organosiliceous catalysts with accessible pendant amine groups as single basic sites (such as propylamine, diethylamine, pyrrolidine) and Pd nanoparticles was prepared ...

[EN] By combining theoretical modelling, in situ spectroscopy and kinetic studies it is possible to understand, at the molecular level, the role that the different types of active centres co-existing on real heterogeneous ...

[ES] El dióxido de carbono es uno de los principales gases de efecto invernadero que causa el calentamiento global de nuestro planeta, con un impacto indiscutible sobre el cambio climático. Para reducir las emisiones de ...

[EN] In this study, niobia-based materials have been used as supports for Pt nanoparticles and used in the hydrogenation of furfural. The incorporation of dopants (W6+ and Ti4+) in the Nb2O5 structure induced modifications ...

[EN] Graphene obtained by pyrolysis of alginate at 900 degrees C under inert atmosphere and exfoliation is used as a metal-free catalyst for reduction of nitro to amino groups with hydrogen as a reagent. The process is ...

[EN] Ruthenium nanoparticles with a core-shell structure formed by a core of metallic ruthenium and a shell of ruthenium carbide have been synthesized by a mild and easy hydrothermal treatment. The dual structure and ...

Bifunctional MIL-101 MOFs containing Lewis acid Cr3+ sites and Pd or Pt hydrogenation/reduction centers, either as isolated metal complexes or in the form of encapsulated metal nanoparticles, have shown to be highly active ...

[EN] In 1996 surprising changes in the optical properties of Rare Earth (RE) thin films (100-200 nm) under metal-hydride reversible transitions were discovered. Later, other materials were discovered displaying optical ...

[EN] In this project the influence of design variables, such as reagent concentration, solvent, temperature and pressure, was investigated in cascade type reactions between aromatic nitro compounds, aldehydes and hydrogen ...
