TL;DR: In this paper, the sulphidation of a nickel-tungsten catalyst has been studied by XPS and electron microscopy and it was observed that for a sulphidation temperature of 400°C, only 70% of the tungsten atoms are in a WS 2 -like form; this proportion increases to 95% at 650°C.

Effect of MoS2 morphology on the HDS activity of hydrotreating catalysts
TL;DR: In this article, high-resolution electron microscopy (HERM) was used to examine Mo/Al2O3 and Mo/ZrO2-Y 2O3 catalysts in thiophene hydrodesulfurization.

Ruthenium sulphide catalysts supported on alumina : physicochemical characterization and catalytic properties in hydrotreating reactions
TL;DR: In this article, the properties of the catalysts in thiophene hydrodesulphurization, biphenyl hydrogenation and pyridine conversion have been investigated and interpreted in relation to their characterization by X-ray photoelectron spectroscopy, high resolution electron microscopic observations and temperature-programmed reduction data.

New method for the preparation of hydrodesulphurization catalysts: Use of the molybdenum sulphur cluster compound (NH4)2[Mo3IVS13]
TL;DR: In this article, a method which appears very promising and general for the preparation of sulphide catalysts is described, which consists in the direct use of metal sulphur cluster (NH 4 ) 2 Mo 3 (S)(S 2 ) 6 ] as precursor for preparation of molybdenum sulphide based catalysts.

Preparation and characterization of highly active ruthenium sulphide supported catalysts
TL;DR: In this paper, the properties of the catalysts in thiophene hydrodesulphurization are interpreted in relation to the XPS characterizations, showing the importance of the sulphidation step in the absence of hydrogen in order to obtain a well sulphided, well dispersed and highly active catalyst.
