Yttrium-modified bulk Ni₂P (Y_xNi₂P) catalysts showing high hydrodesulfurization (HDS) activity are described. The incorporation of Y into the bulk Ni₂P catalyst can suppress the formation of the Ni₅P₄ phase and therefore promote formation of the more active Ni₂P phase. Y can also greatly increase the surface area of the catalyst, leading to a smaller crystallite size and better dispersion of active Ni₂P particles. The obtained Y_xNi₂P catalysts show much higher Dibenzothiop (DBT) HDS activity than the bulk Ni₂P catalyst.
