Thiophene hydrodesulfurization over transition metal surfaces: structure insensitive over molybdenum and structure sensitive over rhenium
Journal Article

· J. Catal.; (United States)
In this note the authors present results of thiophene hydrodesulfurization (HDS) experiments over molybdenum and rhenium single crystals. Previous work in their laboratory showed that a Mo(100) single crystal catalyzes thiophene HDS and that the product distribution is similar to the distribution obtained over an unsupported molybdenum disulfide (MoS/sub 2/) catalyst. The similarity of these results suggests that by determining the effects of surface structure and adsorbate overlayers (C, S) on thiophene HDS over molybdenum single crystals, one can gain insight about the nature of the active sites on MoS/sub 2/-based catalysts. This led the authors to expand studies to molybdenum single crystals of different surface orientations. They have also begun to investigate thiophene HDS over rhenium single crystals; rhenium disulfide (ReS/sub 2/) has been shown to be a more active HDS catalyst than MoS/sub 2/.
