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, H2-TPR, XPS and EXAFS in order to elucidate the key factors that influence the unique catalytic performances observed.
