Abstract: WS2, ReS2, and NbS2, sulfide catalysts with the crystal structure: of the molytbdenite (MoS2) type, are synthesized at the SiO2 surface with the use of metal complexes. Bimetallic Cu-WS2, Ni-ReS2, and Ni-NbS2 catalysts are obtained by anchoring Ni and Cu as their acetylacetonate complexes on the above sulfide catalysts. The bimetallic catalysts are characterized by electron microscopy, XPS, and EXAFS. It is shown that in all cases, a sulfide bimetallic compound (SBMC) of the corresponding composition and structure typical of the active component of Ni-Mo and Ni-W sulfide catalysts for hydrodesulfurization is formed at the SiO2 surface. The detail structure of ultradispersed SBMC particles and the electronic structure of the metals incorporated are discussed in terms of electroneutrality of a SBMC macromolecule.
