The evacuated MoS/sub 2/ surface has two kinds of active sites with different degrees of coordinative unsaturation named B-sites and C-sites. The hydrogenation of ethylene, the exchange between D/sub 2/ and C/sub 2/H/sub 4/ and the H/sub 2/--D/sub 2/ equilibration proceed on the CH/sub 2/ and CH-sites; however, the BH-sites promote the hydrogen exchange between C/sub 2/H/sub 4/ and C/sub 2/D/sub 4/. The hydrogen addition on the CH/sub 2/-sites should maintain the hydrogen molecular identity, but facile reverse process of the ethyl intermediate on the CH/sub 2/-sites lowers the conservation of the hydrogen molecularity in the ethane compared with the other olefins. By treating with H/sub 2/S, the C-sites on the surface are diminished, but the specific sites remained in the layer of the MoS/sub 2/ promote the H/sub 2/--D/sub 2/ equilibration.
