Ethanol and Fluorinated Ethanol Decomposition on Single Crystal Platinum Surfaces: Structure Sensitivity and Electronic Effects

To study the surface work function effect on the surface reaction mechanism, ethanol and fluorinated ethanol decomposition have also been studied on clean and oxygen precovered (2 x 1)Pt(110) surface. The reaction mechanism is very similar on clean (2 x 1)Pt(110) as on Pt(331), except the ethanol C-C bond scission is suppressed on Pt(110). On oxygen precovered (2 x 1)Pt(110) surface the C-C bond scission occurred at higher temperature than on Pt(331), but from the slope of the Hammett plot, it is shown that on (2 x 1)Pt(110) the hydrogen has less charge than on Pt(331), which can be expected from the higher surface work function of the Pt(110) surface.
