Abstract:This review provides an overview of heterogeneous bimetallic Pd-Fe catalysts in the C-C and C-O cleavage of platform molecules such as C2-C6 polyols, furfural, phenol derivatives and aromatic ethers that are all easily obtainable from renewable cellulose, hemicellulose and lignin (the major components of lignocellulosic biomasses). The interaction between palladium and iron affords bimetallic Pd-Fe sites (ensemble or alloy) that were found to be very active in several sustainable reactions including hydrogenolysis, catalytic transfer hydrogenolysis (CTH) and aqueous phase reforming (APR) that will be highlighted. This contribution concentrates also on the different synthetic strategies (incipient wetness impregnation, deposition-precipitaion, co-precipitaion) adopted for the preparation of heterogeneous Pd-Fe systems as well as on the main characterization techniques used (XRD, TEM, H 2 -TPR, XPS and EXAFS) in order to elucidate the key factors that influence the unique catalytic performances observed.

“…For this purpose, carbon supports such as activated carbon, carbon nanofibers or carbon nanotubes are considered to be good candidates [35,39,[62][63][64]. Titanium oxide and silica are also highly valued [18,54,65]. Lastly, alumina, as a conventional support for heterogeneous catalysis, is often studied for the transformation of sorbitol, though its stability in aqueous phase is questionable: gamma alumina rehydrates into boehmite in a few hours under hydrothermal conditions close to APP or APR [22,23,49,66].…”

Résumé -Transformation du sorbitol en biocarburants par catalyse hétérogène : considérations chimiques et industrielles -La raréfaction du pétrole et l'augmentation conjointe de la demande en carburants ont conduit à la recherche de carburants alternatifs. Dans un premier temps, la valorisation de ressources agricoles alimentaires pour la production d'éthanol et de biodiesel a permis de développer les biocarburants de première génération. Aujourd'hui les travaux de recherche s'orientent vers l'utilisation de biomasse lignocellulosique comme source de carbone renouvelable (biocarburants de deuxième génération). Alors que la filière de l'éthanol cellulosique est en plein développement, une nouvelle voie consistant à transformer des sucres et polyols d'origine lignocellulosique en alcanes légers par catalyse hétérogène bifonctionnelle en phase aqueuse a été récemment décrite. Ce procédé s'effectue à basse température et pression modérée (T < 300 °C et P < 50 bar). Il nécessite, d'une part, la formation d'hydrogène par reformage catalytique de carbohydrates en phase aqueuse et, d'autre part, la déshydratation/hydrogénation de polyols conduisant à un alcane par ruptures sélectives des liaisons C-O. Un défi lié à cette thématique réside dans le développement de systèmes catalytiques multifonctionnels stables, actifs et sélectifs dans les conditions de la réaction de transformation. L'objectif de l'article est de présenter les réactions mises en jeu, les systèmes catalytiques décrits dans la littérature pour ce type de transformation ainsi que des exemples d'applications industrielles.

“…For instance, Huber et al (2004) showed that D-sorbitol can be converted to n-hexane in high yield using Pd and Pt catalyst on SiO 2 or Al 2 O 3 (225-265 °C and 26-58 bar). Over Ru/SiO 2 , hydrogenolysis of Dsorbitol at 180-240 °C and 80-125 bar hydrogen pressure yields mainly glycerol and 1,2-propanediol (Sohounloue et al, 1982) (Scheme 3). This implies that C-C bond cleavage occurs readily, leading to the formation of lower molecular weight products.…”
