Abstract:	Reactivity studies of the effect of SCN-, a weaker anion than I-, on the peroxide reduction catalyzed by Pb underpotential deposition (upd) on Au(111) revealed that SCN- decreases the catalytic peroxide reduction activity. The decrease in reactivity due to SCN- exhibited Langmuir behavior. STM studies reveal that islands of two different heights emerge following addition of SCN-. One type of islands is of the same composition prior to SCN- addition. The other type of island exhibits open Pb structures resulting from Pb and SCN- interactions. The open Pb structure exhibits a linear motif, a pattern that is uncommon among upd systems on hexagonal substrates.
