Abstract
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.
