Patterns of reactivity for Ni(110) with organosulfur compounds

OSTI ID:6347437
Reactions observed between Ni(110) and various organic and organosulfur compounds are summarized. Sulfhydryl bonds are cleaved at 100 K on Ni(110) surfaces. After some initial decomposition, thiolate species are stable up to 200--250 K, when C-S bond scission commences. Scission of the C-O bond in alcohols and related compounds is not observed. In mercaptoethanol, the order of bond scission is S-H < C-S < C-H < C-C < C-O which is consistent with both [beta]-hydroxyethylthiolate and ethoxide formation. Surface oxygen and sulfur both passivate the surface with respect to C-H and C-S bond scission reactions, and surface oxygen is also very reactive toward abstracting sulfhydryl hydrogen to form O-H bonds.
