The aluminium–alcohol interface: Methanol on clean Al() surface

Adsorption of methanol and methoxy on NiAl(110) and Ni3Al(111): A DFT study

“…At low temperatures molecular methanol adsorption is most frequently observed. By increasing the temperature, normally to around 200 K, it decomposes to methoxy by O-H bond scission, as observed experimentally on Ni [24][25][26], Al [27] and NiAl alloy [28][29][30][31] surfaces. The preferred adsorption sites and local adsorption geometry of methanol and methoxy are of fundamental interest as these properties serve as a starting point for any further investigation of the adsorbate-surface interactions.…”

CO and methanol adsorption on (2 × 1)Pt(110) and ion‐eroded Pt(111) model catalysts

“…The spectra obtained at 125 and 140 K reveal three peaks at binding energies of 12.5, 10.7, 5.8 eV and a shoulder at 7.2 eV. These peaks correspond to the 5a′, 1a″ + 6a′, 2a″ and 7a′ molecular orbitals of gas phase methanol,33 however, they are shifted to lower binding energies, which is typical for physisorbed methanol 2, 34–37. The 5a′ level has OH character whilst the feature at 10.7 eV has strong CH 3 (1a″) and CO character (6a′) 34, 37.…”

Proton sputtering from polycrystalline Al surface interacting with highly charged ions at grazing incidence angle

“…The steady state adsorbate coverage H(1) after ion beam irradiation at normal incidence for sufficient time is defined as U ad /(U i + U ad ), where U i and U ad are the effective fluxes of incident ions and incoming atoms or molecules, respectively [23]. Since U i « U ad (U ad % 5 · 10 9 atoms cm À2 s À1 in the case of 1 · 10 À7 Pa at room temperature), we consider that the present study was conducted under H(1) $ 1, which changes the surface work function by less than 10% [29].
