Reaction surfaces and interfaces of metal sulfides: cryo-XPS meets HAXPES and DFT

Abstract

Cryo-XPS study of fast-frozen particulate PbS and ZnS in aqueous solutions allows the minimizing of the distortions of the reaction interfaces.

Photo‐Induced Microfluidic Production of Ultrasmall Glyco Gold Nanoparticles

“…The complete reduction of gold was proven by X-ray photoelectron spectroscopy (XPS) that showed a good match with the metal reference, without evidence of Au + species, while the peaks appear slightly larger due to the nanosized nature of the UAuNPs (Supporting Information, Figure S5). XPS also confirms the presence of S coordinated with Au species, as attested by the position of S 2p (162.5 eV) [32] and the C-C and C-O species are attributable to the functionalization of the UAuNP 10.1002/anie.202210140…”

Copper Thiophosphate (Cu3PS4) as an Electrode Material for Lithium Solid‐State Batteries with Lithium Thiophosphate (β–Li3PS4) Electrolyte

“…This indicates that the XRD features at 26.8°and 44.4°(2θ) (see Figure 4b(VI)) arise from Cu 2 S and not Li 2 S. No S 8 signals were detected in the S2p XPS spectrum after charging, which can occur due to evaporation of sulfur under UHV conditions. [33] The XPS results demonstrate that the Cu 3 PS 4 reacts with lithium according to a different mechanism than with sodium. Li 2 S is observed alongside the formation of P-[S] n -P intermediates at the SOC of II and prior to the formation of Cu 0 when the cell is fully discharged to 0.8 V. In line with the literature, the P-[S] n -P intermediates were found to be redox active according to changes in their relative intensities in the P2p spectra for different states of charge.…”
