CO and C<inf>3</inf>H<inf>6</inf> poisoning of hydrogen permeation across Pd<inf>77</inf>Ag<inf>23</inf> alloy membranes: A comparative study with pure palladium
2022, Chemical Engineering JournalCitation Excerpt :The peak centered at ∼ 2080 cm−1, which was not observed in the PM-IRAS spectra of Pd (see Fig. 2(a)), is consistent with CO adsorbed linearly on top of Pd atoms [71,72]. We did not observe any bands associated with CO adsorbed on Ag atoms at above 2100 cm−1 [73–75], which is not surprising as CO adsorption on silver sites is energetically unfavorable at temperatures above ∼ 120 K [76]. The PM-IRAS spectra of Pd77Ag23 are consistent with recent DFT calculations by Svenum et al. of CO and hydrogen co-adsorption on Pd-terminated Pd3Ag(1 1 1) [70].
Insights into the binding interactions at the nano-bio interface: Electrode potential and wavelength dependence study
2021, Applied Surface ScienceCitation Excerpt :On the contrary, the spectrum of chemisorbed molecule differs significantly in relation to the conventional RS spectrum, i.e. alterations in bandwidth, wavenumber, and relative intensity [9]. Consequently, the enhancement factor for the chemisorbed molecule is much higher than for the physisorbed compound, which indicates the chemical interaction between the metal and the molecule [10]. Such differences may result from the molecular and metal orbital overlapping that induces the special surface complex creation [11,12].
Interaction of CO with Pt<inf>x</inf>Ag<inf>1-x</inf>/Pt(111) surface alloys: More than dilution by Ag atoms
2016, Surface ScienceCitation Excerpt :Due to the low coverage of these COad species we could not detect an IR band which could be correlated with the low temperature desorption feature. Such bands were reported previously, however, for surfaces with a high enough concentration of Ag defect sites, which were created e.g., by Ag deposition at low temperatures (Ag/Ag film [78], Ag/Pt(111) [74]). For these surfaces, bands around 2150 cm− 1 were associated with COad species on these Ag defect sites, both for Ag/Ag film and for Ag/Pt(111).
Kinetics of low-temperature CO oxidation on Au(111)
2016, Surface ScienceCitation Excerpt :This shows a decrease in the intensity of the infrared peaks and the inset plots the integrated absorbance of the infrared features as a function of annealing temperature. An additional shift in peak position is noted as the CO coverage changes due to a combination of dipolar coupling and chemical shifts [49,50]. The CO vibrational frequency of 2110 cm− 1 is in good agreement with results for high pressures of CO on Au(110) [51] and for CO adsorption at low temperatures on Au(211) [39] and Au(332) surfaces [42].
Surface enhanced Raman spectral studies of 2-bromo-1,4-naphthoquinone
2015, Spectrochimica Acta - Part A: Molecular and Biomolecular SpectroscopyCitation Excerpt :Molecule chemisorbed on metal surface show a larger enhancement than the physisorbed molecules, signifying some chemical effect between the molecule and the surface. It is recognized that the adsorption coefficients of chemisorbed molecules are larger than those of condensed over layer [37]. Interaction between adsorbed molecules also affects the intensity.
