The mechanism of the desulfurization of benzenethiol by nickel (110)

Regeneration of an n-decanethiol-poisoned nickel catalyst

“…3b). The first peak corresponds to thiolates [30][31][32], while, the second peak is typical of sulfonates [32,33]. This is in good agreement with the findings obtained in a study of the wetting properties for self-assembled monolayers of n-alkanethiols on copper surfaces [34].…”

“…aliphatic) carbon, originating from the decanethiols chemisorbed on the catalyst surface. This assignment is consistent with adsorbed thiolate [30,31,35].…”

“…Mode assignments for each peak are also listed on the same figure. Peak positions are ∼2850 cm −1 (υ symmetric , CH 2 ), ∼2918 cm −1 (υ antisymmetric , CH 2 ), ∼2930 cm −1 (υ symmetric , CH 3 FR + ) and ∼2955 cm −1 (υ antisymmetric , CH 3 ), respectively [29,30]. The relative intensities of these various peaks, their peak positions and the peaks widths, are remarkably similar to those of alkanethiol monolayers, as adsorbed on planar Au(1 1 1) substrates [26,27], suggesting that the local environment for these adsorbates on the Ni surface is a rather well ordered one, despite the long-range disorder implicit in the use of powdered surface substrates.…”

Adsorption and Reactions of Benzenethiol on the Ni(111) Surface

“…* On Mo(llO), similar dissociative adsorption of the thiol occurs, and the aromatic ring in the phenyl thiolate is tilted 23" away from the surface normal, as determined by near-edge X-ray absorption fine structure analy~is.~ In addition, adsorbed benzyne ( C a ) was reported to exist as a stable surface intermediate on Mo- (1 10). HREELS experiments on benzenethiol adsorption on Pt- (1 11) and Ag( 11 1) electrodes indicate that phenyl thiolate is formed and that its ring is normal to the The reactions of benzenethiol have been 'studied on Ni( 1 10) and Mo ( 1 In both cases, benzenethiol produces gas phase hydrogen and benzene. On both of these surfaces, the benzene reaction product desorbs over a fairly wide coverage range.…”

Effective Bipyridine and Pyrazine‐Based Polysulfide Dissolution Resistant Complex Framework Material Systems for High Capacity Rechargeable Lithium–Sulfur Batteries

“…C1s spectra of the CFM electrodes before and after 150 charge–discharge cycles at 0.2 C rate are shown in Figure . Both the CFM electrodes exhibit the peak at 290.40 eV that represents the —(CF 2 —CF 2 )— group arising from the polyvinylidene fluoride (PVdF) binder (289.87 eV), the peak at 286.10 eV corresponding to the —(C—S)— bond arising from the binding of sulfur to the ring carbon atoms, and the peak at 284.2 eV corresponding to other ring —(C 6 H 4 S)— bonds. The presence of these C–S peaks confirms the existence of sulfur–carbon binding observed in the S2p spectrum (Figure ) and supports the findings that this chemical linkage between the sulfur and carbon species created during the sulfur infiltration process aids in polysulfide retention within the CFM structures.…”
