Based on the experimental data of the study of highly dispersed sulphided (Ni-W)/SiO2 and (Ni-Mo)/SiO2 catalysts prepared from organometallic precursors, the structures of the active phase and active centers for C-S bond hydrogenolysis are discussed. The active phase of hydrodesulphurization catalysts represents layered sulphide structures with the same M-S and M-M (M=W or Mo) distances as in bulk disulphides. A single MS2 sheet is a sufficient structural element for the formation of active centers. It was suggested that the active centers include Ni atoms, on which thiophene adsorption occurs, and W(Mo) atoms of the side planes of the MS2 sheet. Sulphur atoms bound with one Ni atom are involved in the catalytic cycle.
