“…This implies that at low temperature, the intact methanethiol prefers a local atop site on the regular Cu(111) surface [4]. As the temperature increased, the energy barrier can be overcome and the hydrogen is detached from the S atom, which is consistent with the experimental observation [4,6,7].…”

“…At room temperature, when methanethiols or dimethyl disulfides adsorbed on the Cu(111), the formation of the pseudosquare reconstruction was observed via scanning tunneling microscopy [5,6]. A grazing incidence surface X-ray study indicates that intact alkanethiols favor hollow sites on Cu(111) [7]. However, there has been no experimental proof for hydrogen desorption from such processes.…”

We demonstrate that when a methanethiol adsorbed on the regular Cu͑111͒ surface, the dissociative structure is thermodynamically more stable than the intact one. The computational results show that at low temperature, the methanethiol adsorbate prefers the atop site of the regular Cu͑111͒ surface. As the temperature is increased, the S-H bond is broken and the methylthiolate favors the hollow sites. On the defected Cu͑111͒ surface, the dissociative configuration is still thermodynamically more stable than the nondissociative one. The calculation indicates that the hydrogen initially attached to the sulfur would like to form a bond with the copper surface rather than desorb from it. Even though both copper and gold are the noble metals, the stability of the methanethiol adsorption on the Cu͑111͒ substrate is almost the reverse of that on the Au͑111͒.

“…In addition, the information is limited only to the chemical states of metal species. To circumvent this problem one can apply grazing-incidence XAS (GIXAS) (Floriano et al, 2000) or total-electron-yield (Erbil et al, 1988) XAS which can provide both structural and chemical information on the surface layers of the material. However, these techniques do not render depth-resolved information and are limited to thin films studies.…”

Energy-resolved electron-yield X-ray absorption spectroscopy is a promising technique for probing the near-surface structure of nanomaterials because of its ability to discriminate between the near-surface and bulk of materials. So far, the technique has only been used in model systems. Here, the local structural characterization of nanoporous cobalt-substituted aluminophosphates is reported and it is shown that the technique can be employed for the study of open-framework catalytically active systems. Evidence that the cobalt ions on the surface of the crystals react differently to those in the bulk is found.

“…Upon adsorption of sulfur containing molecules on metal surfaces, a strong sulfur-metal interaction establishes and the orientation of molecules are affected by the nature of sulfur-metal interface [1] also charge transfer occurs from metal to molecules [2][3][4]. These characteristics give rise to the unique physico-chemical properties of the interface.…”
