Sumari:New technologies for production of bulk catalysts require that the available catalyst systems be essentially improved. The advantage of bulk catalysts on inflicted catalysts is in the freedom to vary the active component concentration in a wide range of values. Bulk sulfide catalysts are usually prepared by co-precipitation, mechanical activation of precursor salts and micelar synthesis of solid sulfide particles. Furthermore Мо/W and 3d-metal oxides are always formed as intermediates. According to the literature attempts to obtain highly active catalyst for hydrogenolysis from macrocrystalline MoS2 failed to be success. In this paper we present the results on direct solid-phase synthesis of sulfide catalysts based on different MoS2 (MoS2, obtained by self-propagating high-temperature synthesis from electroexplosive Мо nano-powder and elemental S, Fig.1а, and commercial macrocrystalline product, Fig.1b), as well promoters taken as electro-explosive nano-sized Ni and Со powders or micron-sized powders. Nano-fiber γ-AlOOH (Fig.1d), obtained from electro-explosive nano-powder AlN and detonation nano-diamonds were used as binders. Solid-phase synthesis of the catalytic systems was carried out via mechanical activation of MoS2 and promoters at dispersion during 4 - 24 hours.
