“…Its stoichiometric formula is written as Cu(I) 2 Cu(II)Sn(IV)S 4 with a random distribution of Cu(I), Cu(II) and Sn(IV) ions in the available tetrahedral sites [32]. In the present research, other minor peaks of C 1s (284.9 eV) and O 1s (531.4 eV) were also detected [7,[25][26][27]. They belonged to the coated carbon to improve electrical conductivity for XPS analysis and the absorbed gaseous molecules in the characterized product.…”

“…No evidence of Sn 2+ (binding energy at 485.2 eV) was detected in the spectra. The S 2p core level spectrum indicates the binding energy at 161.8 eV for MR and 161.7 eV for CR [7,8,[24][25][26][27][28][29][30]. Furthermore, additional peaks were detected (MR = 169.1 eV, CR = 168.8 eV) and seemed to be from the oxidized parts of the product during the synthesis.…”

“…The nitrogen derived from amine functional groups of PPy can contribute to the higher electron conductivity and electrolyte permeability. The dominant two peaks of S2p in Figure D at 163.8 and 161.5 eV are ascribed to S2p 1/2 and S2p 3/2 in the Cu 2 S . The weak peak located at 162.5 eV is attributed to C−S band .…”

Cu2S is considered as a promising electrode material for lithium‐ion and sodium‐ion batteries owing to its flat charge‐discharge plateau as well as the abundant reserves. However, serious capacity fading and formation of polysulfides during electrochemical process restrict its practical application. In this work, a new type of Cu2S@N, S dual‐doped carbon matrix (Cu2S@NSCm) hybrid is synthesized through a simple in‐situ polymerization process and subsequent carbonization process. Due to the N, S dual‐doped carbon matrix, which can buffer the volume change, restrain the dissolution of polysulfide and enhance the electron conductivity during electrochemical process, the hybrid demonstrates excellent electrochemical performance. The Cu2S@NSCm hybrid exhibits a reversible capacity of 560.1 mAh g−1 at a current density of 1000 mA g−1 after 550 cycles when used in lithium‐ion batteries, which is among the best performance for Cu2S based anode materials. Moreover, a capacity of 182.3 mAh g−1 is obtained after 50 cycles when used as an anode material in sodium ion batteries, which is much better than the pure Cu2S.

We substitute indium by iron and zinc in CuInS 2 ternary compound using a facile one-pot synthesis method. The quaternary compound of CuIn x M 1-x S 2 (M=Fe and Zn) was synthesized by solving of CuCl, InCl 3 , FeCl 3 , Zn(ac) 2 and SC(NH 2 ) 2 as precursors in 1-octadecene, oleylamine and oleic acid as non-coordinating, coordinating and capping agent solvents, respectively. The oleic acid, oleylamine and thiourea were used respectively as a hard Lewis base, borderline Lewis base (in compare with oleic acid) and soft Lewis base to form of appropriate complex. The complex formation, structure, and optical of CuIn 1-x M x S 2 (M=Fe and Zn) nanoparticles were studied by Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), X-Ray photoemission spectroscopy (XPS), transmission electronic microscopy (TEM), ultraviolet-visible-near infrared (UV-Vis-NIR) and photoluminescence (PL) spectroscopy. Absorption edge of solid solution samples can be tuned from 745 nm (visible) to 1200 nm (near infrared) by substitution In 3+ by Zn 2+ and Fe 3+ , respectively.
