Adsorption of the formate species on copper surfaces: a DFT study
The density functional theory and the cluster model approach have been applied to study the interaction of the formate species with the copper (100), (110) and (111) surfaces. The short-bridge, long-bridge and cross-bridge sites of the copper surface have been modelled by Cu7 and Cu8 metal clusters after checking the validity of the results against those obtained with much larger clusters. The ...
متن کاملProbing the reactivity of ZnO and Au/ZnO nanoparticles by methanol adsorption: a TPD and DRIFTS study.
The adsorption of methanol on pure ZnO and Au-decorated ZnO nanoparticles and its thermal decomposition monitored by temperature-programmed desorption (TPD) experiments and by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), both applied under continuous flow conditions in fixed bed reactors, is reported. Two distinguishable methoxy species are formed during methanol adsorp...
متن کاملFace-dependent bond lengths in molecular chemisorption: the formate species on Cu(111) and Cu(110).
Many previous structural studies of molecular adsorbates on metal surfaces indicate that the local coordination and bonding is closely similar to that in organometallic compounds, implying that the metallic substrate has no significant influence. Here we show that such an influence is detectable for one model system, namely, the formate species, HCOO, adsorbed on the atomically rough and smooth...
متن کاملEnantioselective separation on naturally chiral metal surfaces: D,L-aspartic acid on Cu(3,1,17)(R&S) surfaces.
Homochirality of amino acids, sugars, proteins, and DNA is one of the biochemical hallmarks of life on Earth. Its origins have been debated for decades. Given that minerals such as quartz were probably the first enantiomerically pure materials on Earth, it has been suggested that such materials served as chiral substrates for enantiospecific surface chemistry. Enantiospecific adsorption on the ...
متن کاملLow-temperature mobility and structure formation of a prochiral aromatic thiol (2,5-dichlorothiophenol) on Cu(111).
We present a low-temperature scanning tunneling microscopy study of increasing coverages of 2,5-dichlorothiophenol, an asymmetrically halo-substituted aromatic thiol, on Cu(111). At low coverage, deprotonation of the thiol occurs spontaneously upon adsorption at 80 K. Albeit the low deposition temperature, we find the formation of adsorbate islands at low coverage, which coalesce into a well-or...
