Abstract:
The reaction of a saturated layer of Hads with NO on the unreconstructed Pt(100)-(1 × 1) surface at 300 K has been studied by high-resolution electron energy loss spectroscopy (HREELS) and temperature programmed reaction spectroscopy (TPRS). The NH2ads species is produced as an intermediate of the reaction. The vibrational losses of NH2ads at 480 cm−1 (ν(PtNH2) stretching), 825 cm−1 (ω(NH2) wagging), 1450 cm−1 (δ(NH2) scissors), 3298 cm−1 (νs(NH2) symmetric stretching) and 3388 cm−1 (νas(NH2) asymmetric stretching) are observed. The hypothesis of the formation of NH2ads is supported by modeling by means of the Wilson GF matrix method and the simplest valence force approximation. The reaction of an adlayer consisting of a 1:1 mixture of HadsDads with NO produces an isotopic mixture of NH2ads, ND2ads and NHDads. The vibrational spectra of NH2ads and its isotopic counterparts ND2ads and NHDads have been discussed in detail. Based on the detailed analysis of the vibrational modes, the NH2ads species is suggested to occupy the bridge adsorption place with C2v symmetry.
