Metal phosphides (Ru2P, RuP, MeRuP) supported on silica were prepared and their properties for furan and guaiacol hydrodeoxygenation (HDO) were investigated.  The HDO properties were compared with those of reduced metal catalysts having the same metal loading as the phosphide catalysts.  The HDO activity was observed to depend strongly on the P/Ru molar ratio of the catalyst precursors, with the maximum furan HDO activity observed for a Ru2P/SiO2 catalyst prepared from a precursor having P/Ru = 0.86.  The product selectivities of the metal phosphide (e.g. Ru2P/SiO2) and reduced metal catalysts (e.g. Ru/SiO2) differed significantly.   The HDO activities and selectivities were also strongly influenced by the identity of the second metal (Me) in bimetallic phosphides of the form MeRuP.  The observed trends in HDO activity and selectivity, as well as the resistance to poisoning of the metal phosphide catalysts will be discussed.
