l ‐Lysine Stabilized FeNi Nanoparticles for the Catalytic Reduction of Biomass‐Derived Substrates in Water Using Magnetic Induction

Résumé

The reduction of biomass‐derived compounds gives access to valuable chemicals from renewable sources, circumventing the use of fossil feedstocks. Herein, we describe the use of iron‐nickel magnetic nanoparticles for the reduction of biomass model compounds in aqueous media under magnetic induction. Nanoparticles with a hydrophobic ligand (FeNi 3 ‐PA, PA=palmitic acid) have been employed successfully, and their catalytic performance is intended to improve by ligand exchange with lysine (FeNi 3 ‐Lys and FeNi 3 @Ni‐Lys NPs) to enhance water dispersibility. All three catalysts have been used to hydrogenate 5‐hydroxymethylfurfural into 2,5‐bis(hydroxymethyl)furan with complete selectivity and almost quantitative yields, using 3 bar of H 2 and a magnetic field of 65 mT in water. These catalysts have been recycled up to 10 times maintaining high conversions. Under the same conditions, levulinic acid has been hydrogenated to γ‐valerolactone, and 4’‐hydroxyacetophenone hydrodeoxygenated to 4‐ethylphenol, with conversions up to 70 % using FeNi 3 ‐Lys, and selectivities above 85 % in both cases. This promising catalytic system improves biomass reduction sustainability by avoiding noble metals and expensive ligands, increasing energy efficiency via magnetic induction heating, using low H 2 pressure, and proving good reusability while working in an aqueous medium.
