Abstract:
Bimetallic sulphided (Ni,W)/SiO2 and (Ni,Mo)/SiO2 catalysts prepared from W(Mo) and Ni organometallic precursors were studied by transmission high resolution electron microscopy. It was shown that addition of Ni to sulphided W(Mo)/SiO2 catalysts with further sulphidization results in the formation of thread-like structures ∼ 25 A long. Mostly these structures are single; when they form assemblies the distance between neighbouring threads is ∼6A, which corresponds to the distance between separate sheets in WS2 (MoS2) crystals. Comparison of morphology and catalytic activity of “organometallic” and “standard” catalyst samples gives evidence that the active centers of thiophen hydrogenolysis are located on the side planes (or edges) of dispersed WS2(MoS2) crystals.
