Abstract

Reduced tin and lanthanum molybdenum sulfides prepared by a low-temperature synthesis route are active catalysts for hydrodesulfurization (HDS). Hydrogen pretreatment at temperatures below 600°C produces amorphous materials, while higher temperature pretreatment results in the formation of Chevrel phases. Spectroscopic (FTIR, Raman, XPS) and EXAFS characterization have confirmed that the Mo₆S₈ clusters are the primary structural unit in these ternary molybdenum sulfide catalysts.
