X-ray photoelectron spectroscopy of S2N2 and the solid state polymerization of S2N2 to metallic (SN)x

Abstract

An x-ray photoelectron spectroscopic (XPS) study of a thin film of S2N2 at −100 °C, involving the valence band, core-level and core-level shakeup, and energy-loss spectra, is reported. The results are analyzed in terms of a molecular orbital model and previous optical data. In addition, the thermally induced solid state polymerization of S2N2 to metallic (SN)x was studied by recording the XPS spectra at −40, 0, and 20 °C. The valence band data show changes of the highest filled molecular orbitals of S2N2, consistent with the process of polymerization to the metallic state.

Tuning of Na+ Concentration in an Ionic Liquid Electrolyte to Optimize Solid–Electrolyte Interphase at Microplasma-Synthesized Graphene Anode for Na-Ion Batteries

“…At 0.5 M, the formed SEI is Na-deficient (see Table ). Figure a also reveals a relatively low intensity of Na, which is mainly in Na–O bonding form (such as Na 2 O/NaOH). , In the S 2p spectrum (Figure b), peaks corresponding to −SO 4 – (169.8 eV), −SO 2 – (168.1 eV), and SO X (166.1 eV) species, which resulted from FSI – decomposition, were found. , The N 1s spectrum (Figure c) consists of N–C (402.9 eV), N–O (400.2 eV), and N–S (397.9 eV) peaks. , The first component was associated with the reductive decomposition of PMP + , and the latter two components were derived from FSI – . The decomposition (both cations and anions) of the 0.5 M electrolyte was notable (see Table ), leading to excessive SEI formation.…”

Plasma Treatment: a Novel Approach to Improve the Photoelectroactivity of Sb2S3 Thin Films to Water Splitting

“…The profile of the S 2p and N 1s spectra presented substantial changes after plasma treatment. The peaks at 168.3 and 169.3 eV for S 2p, and 401.6 eV for N 1s are most likely assigned to nitrogen bonded to sulphur . It is noteworthy to mention that although the N 1s spectrum reported here overlaps with the one for the antimony(III) nitride (SbN 3 ) which is 401.8 eV (N 1s), the binding energy peaks from the Sb 3d spectrum of SbN 3 (539.6 and 530.2 eV for Sb 3d 5/2 and 3d 3/2 , respectively) differ in position compared to those presented here for the film treated under plasma for 10 s (530.8 and 540.2 eV for Sb 3d 5/2 and 3d 3/2 , respectively).…”
