Abstract
A silica-supported hydrodesulfurization (HDS) model catalyst with well-ordered pore structure was prepared by depositing Ni and Mo on the surface of silica opal. Using the voids of ordered packing of monodisperse silica microspheres, the pores of the model catalyst are wholly open-through and uniformly distributed. The ordered pore structure and regular smooth surface of the model catalyst make the surface states of metal oxides readily observable. As a result, the metal oxides were well dispersed on the silica, and the model catalyst exhibited a high activity in HDS of dibenzothiophene.
