Реферат:
The unsupported NiWS-catalyst was obtained from the precursor [Ph3S]2Ni(WS4)2 in a hydrocarbon medium (in situ) for hydrogenation bicyclic aromatic compounds. The precursor [Ph3S]2Ni(WS4)2 and the catalyst prepared on its basis were studied by the X-ray diffraction and X-ray absorption methods, XPS and TEM. It was found that the new catalyst formed in situ contains tungsten sulfide and nickel sulfide nanophases. Tungsten sulfide, which has a layered structure, partially forms an insertion compound with nickel that enters between the WS2 layers and bonds covalently to sulfur. The proposed catalyst has proved to be active in the hydrodearomatization processes of model aromatic compounds (naphthalene, methylnaphthalenes) and exhibited the maximum selectivity with the formation of decalins compared to other earlier studied catalysts formed from other precursors in the reaction medium.
