“…The TPD spectra reported in Fig. 52 show a sequential filling of the states corresponding to NO desorption temperatures of 540 K, 490 K and 355 K on Pd(320) [317]; such values should be compared with the ones of 480 K, 340 K and 260 K measured for Pd (110) [318] (see Fig. 53).…”

“…Nevertheless, modern instrumentation allows detailed investigations, including that of molecular adsorption, sticking probability, desorption, and surface reactions with various reagents. 21,22 In the hyperthermal energy regime ͑ϳ1 to about 100 eV͒, the center-of-mass collision energy is comparable to or greater than typical chemical bond energies. The ion translational energy is large enough to cause bond cleavages but is not so large as to completely transform and so obscure the chemical nature of the projectile/surface collision pair.…”

A 23, 671 (2005); 10. 1116/1.1943452 Surface induced dissociations of protonated ethanol monomer, dimer and trimer ions: Trimer break-down graph from the collision energy dependence of projectile fragmentation An overview of gaseous ion/surface collisions is presented, with special emphasis on the behavior of polyatomic projectile ions at hyperthermal collision energies ͑1-100 eV͒ and the instrumentation needed for such studies. The inelastic and reactive processes occurring during ion/surface collisions are described in terms of several archetypes, viz., elastic and quasielastic scattering, chemical sputtering leading to release of surface material, inelastic scattering leading to surface-induced dissociation ͑SID͒ of the projectile, ion/surface reactions, and soft landing. Parameters that are important in ion/surface interactions are discussed, including the interaction time, the conversion of translational to internal energy, the translational energies of the scattered ions, the effects of scattering angle, and the influence of the nature of the surface. Different types of tandem mass spectrometers, built specifically to study ion/surface collision phenomena, are discussed and the advantages and disadvantages of the individual designs are compared. The role of SID as a technique in bioanalytical mass spectrometry is illustrated and this inelastic collision experiment is compared and contrasted with gas-phase collision-induced dissociation, the standard method of tandem mass spectrometry. Special emphasis is placed on reactive scattering including the use of ion/surface reactions for surface chemical analysis and for surface chemical modification.

“…All together, the results illustrate that the thermal decomposition of NO is structure sensitive with faceted Ir(210) being more reactive and selective to N 2 than planar Ir(210) at high NO coverage. This study [10] also concludes that Ir is more active and selective to N 2 formation than Pt, Rh, and Pd in NO decomposition based on the comparison of TPD spectra from adsorption of saturated NO on planar and faceted Ir(210) at 300 K with those from single crystal Pt [171,172], Rh [71], and Pd [173] surfaces presaturated by NO at room temperature.
