Abstract The preparation and catalytic activity of metal phosphide as catalysts in hydrodesulfurization(HDS), hydrodenitrogenation(HDN), and hydrodeoxygenation(HDO) were reviewed. Reduction of metal compound together with phosphate was a convenient method to prepare metal phosphides, but required high reduction temperatures. Reduction with phosphites, hypophosphites andphosphine, and the plasma reduction of phosphate could be carried out at lower temperatures, which led to smaller metal phosphide particles and more active catalysts. Metal phosphides displayed excellent performance in HDS and HDN, especially Ni2P, which was more active than conventional metal sulfide. Recent studies showed that bimetallic and noble metal phosphides have high activity and selectivity. HDO catalysis over metal phosphides was a growing area of research given the need to develop catalysts for upgrading biomass to transportation fuels. Overall, metal phosphides were promising catalysts for hydrotreating.
