Ni-Fe nanoparticles for the selective hydrogenation of organic molecules: a triple challenge in catalysis, characterization and synthesis
Les nanoparticules Ni-Fe pour l’hydrogénation sélective des molécules organiques : un triple défi en catalyse, caractérisation et synthèse
Résumé
The introduction of iron in bimetallic Ni-Fe nanoparticles allows an efficient modulation of the hydrogenating properties of nickel. Catalysts based on Ni-Fe nanoparticles thus perform the selective hydrogenation of oxygenor nitrogen-containing functions of organic molecules containing unsaturated carbon-carbon bonds or aromatic cycles. But rationalizing their catalytic properties requires a deep knowledge in the localization of the two metals within the nanoparticles, and the identification of synthesis routes leading to Ni-Fe particles of controlled size and composition.
