Abstract
  • NO molecules adsorbed on a Pt(111) surface from dipping in an acidic nitrite solution are studied by nearedge X-ray absorption fine structure spectroscopy (NEXAFS), X-ray photoelectron spectroscopy (XPS), lowenergy electron diffraction (LEED), and scanning tunnelling microscopy (STM) techniques. LEED patterns and STM images show that no long-range ordered structures are formed after NO adsorption on a Pt(111) surface. Although the total NO coverage is very low, spectroscopic features in N K-edge and O K-edge absorption spectra have been singled out and related to the different species induced by this preparation method. From these measurements, we concluded that the NO molecule is adsorbed trough the N atom in an upright conformation. The maximum saturation coverage is about 0.3 ML, and although nitric oxide is the major component, nitrite and nitrogen species are slightly coadsorbed on the surface. The results obtained from this study are compared with those previously reported in the literature for NO adsorbed on Pt(111) under UHV conditions. (literal)
