2p electron binding energies for the sulfur atoms in metal polysulfides

XPS of sulphide mineral surfaces: metal-deficient, polysulphides, defects and elemental sulphur

“…163.2-163.6 eV). 12 Thin layers of sulphur electrochemically deposited by anodic oxidation of sulphide species in solution onto gold and platinum surfaces exhibited BEs corresponding to sulphide species close to the metal interface (i.e. 161.4-161.8 eV).…”

Spectroscopic study of cystine adsorption on pyrite surface: From vacuum to solution conditions

“…However, the intensity of the first component was higher in this case due to contamination during sample preparation in air instead of under UHV conditions; apart from that, no changes in the carbon signals were observed for cystine adsorption under different conditions. , where 2≤n ≤8) and elemental sulfur occur [33][34][35][36].…”

Gold deposition on pyrite and the common sulfide minerals: An STM/STS and SR-XPS study of surface reactions and Au nanoparticles

“…10). The spectra show strong signals from disulfide and polysulfide species at about 162 eV and 163.5 eV, denoting in fact the end and medial atoms in anions S n 2À , n P 2, respectively (Termes et al, 1987;Mikhlin, 2000;Mikhlin et al, 2000). The unreacted minerals include only monosulfide ions, and S-S bonding occurs as a result of a depletion of the oxidized surface layers in metals.…”
