Catalytic deoxygenation is a critical step in the upgrading of bio-oils to renewable biofuels. Transition metal phosphides (Ru2P, Ni2P) have shown promise as hydrotreating catalysts, with similar activity and lower tendency towards deactivation than sulfide-based catalysts. Bimetallic phosphides of ruthenium (MxRu2-xP, M = Co, Ni) with a range of metal compositions have been synthesized and characterized by a number of physicochemical techniques. The bimetallic phosphides form solid solutions over a wide range of compositions and catalysts with high dispersions of the phosphide phase on silica have been prepared. The deoxygenation properties of the MxRu2-xP/SiO2 catalysts have been investigated using furan (C4H4O) and crotonaldehyde (C4H4O) as model organo-oxygen compounds. The deoxygenation properties (activities, selectivities) show a strong dependence on MxRu2-xP composition, which will be discussed in the context of the characterization studies.
