Abstract:A relevant research effort is devoted to the synthesis and characterization of phases belonging to the ternary system Cu-Sn-S, mainly for their possible applications in semiconductor technology. Among all ternary phases, kuramite, Cu 3 SnS 4 , mohite, Cu 2 SnS 3 , and Cu 4 Sn 7 S 16 have attracted the highest interest. Numerous studies were carried out claiming for the description of new phases in the ternary compositional field. In this study, we revise the existing literature on this ternary system, with a special focus on the phases stable in a temperature range at 25˝C. The only two ternary phases observed in nature are mohite and kuramite. Their occurrence is described as very rare. A numerical modelling of the stable solid phases in contact with a water solution was underwent to define stability relationships of the relevant phases of the system. The numerical modelling of the Eh-pH diagrams was carried out through the phreeqc software with the lnll.dat thermodynamic database. Owing to the complexity of this task, the subsystems Cu-O-H, Sn-O-H, Cu-S-O-H and Sn-S-O-H were firstly considered. The first Pourbaix diagram for the two naturally relevant ternary phases is then proposed.

“…Recent studies have pointed out interesting semiconducting performances in some terms of the ternary Cu-Sn-S system [1][2][3][4][5]. Namely, Cu 3 SnS 4 , Cu 2 SnS 3 and Cu 4 SnS 4 are considered as novel materials for the p-layer of thin film technology in solar energy conversion devices.…”

“…Flaky morphology of the sample was identified in the image captured by SEM (Figure a). Such morphology has been reported earlier for metal oxides, apatites, and sulfides prepared with the assistance of microwaves and their formation was accompanied with gas evolution . Multipoint BET surface area of the sample was measured along with a single point pore size distribution analysis.…”

Rapid and One‐Step Transformation of LiAlH₄ to Inorganic and Organic Anion Intercalated Li‐Al Layered Double Hydroxides

et al. 2019

Monoclinic [LiAl2(OH)6]OH·2H2O was formed by the hydrolysis of LiAlH4 within few minutes of irradiation with microwaves as confirmed by powder X‐ray diffraction (PXRD), infrared, Raman, 27Al NMR spectroscopic, and thermal analysis experiments. The flaky morphology of crystallites was evident in microscopy images. The compound is mesoporous with surface area of 50 m2/g. When required amounts of corresponding mineral acids were added during the hydrolysis of LiAlH4, exchange of the interlayer hydroxide ion with nitrate and chloride ions was successful. This was verified by the hexagonal symmetry observed in the PXRD patterns together with the evidence gathered from infrared, 27Al NMR spectra, thermal analyses, and the substantial changes in ligand to metal charge‐transfer bands in their UV/Visible spectra. A host of Li‐Al LDH compounds intercalated with aliphatic dicarboxylate (oxalic, malonic, succinic, glutaric, adipic, and sebacic acid) anions were rapidly produced when a mixture of LiAlH4 and the respective acid was irradiated with microwaves for a few minutes. The basal spacing of the dicarboxylate anion intercalated systems increased linearly with the increase in the number of –CH2‐ groups in them. Microwave assisted reaction of ethylene glycol with [LiAl2(OH)6]OH·2H2O resulted in its intercalation.

“…Sn also exhibits two oxidation states with Sn 3d 5/2 at 487.6 eV and Sn 3d 3/2 at 496 eV elucidating Sn 4 + and the peaks at 486.7 eV and 495 eV assigned to Sn 2 + . [28,29] The S 2p core peaks at 162 eV and 163.3 eV imply the sulfide state of S. [30] This observation matches well with the literature elucidating the presence of mixed oxidation states of the elements in the material.…”

“…The CTS NPs were further characterized by Powder X-ray Diffraction (PXRD), RAMAN spectroscopy, and X-ray photoelectron spectroscopy (XPS) and the data for the material specifically used in this work are presented in Figure 2 with Figure 1 inset, Figure 2b and Figure 2(d)-(f) are reproduced with permission from reference 25 for sake of better understanding. [28,29] The S 2p core peaks at 162 eV and 163.3 eV imply the sulfide state of S. [30] This observation matches well with the literature elucidating the presence of mixed oxidation states of the elements in the material. [25] The nitrogen adsorption desorption isotherm for the CTS NPs in Figure 2c exhibits Type-IV characteristic with a hysteresis which affirms the presence of mesopores in the material.…”

Single‐Phase Cu₃SnS₄ Nanoparticles for Robust High Capacity Lithium‐Ion Battery Anodes

et al. 2019

With the evolution of Li-ion batteries, they have been employed in many applications. However, high energy density and power density batteries are yet to be developed to meet the necessities at the application end. Sulfides are a good choice as anode material as they show a much higher specific capacity than conventional graphite anodes. But unfortunately, sulfide dissolution and polysulfide shuttling are big drawbacks for their operation. Herein, single phase ternary metal sulfide Cu 3 SnS 4 (CTS) nanoparticles are synthesized with high Cu : Sn ratio and examined for application as Li-ion battery anode. High specific capacities of 1082 mAh g À 1 at 0.2 A g À 1 and 440 mAh g À 1 at a high rate of 3 A g À 1 are realized with superior stability tested up to 950 cycles. Utilizing the CTS NPs can minimize the polysulfide dissolution. The high Cu : Sn ratio provides excess Cu atoms as the buffer matrix for volume expansion of Sn, leading to high stability and specific capacity. Compared to other reported Cu based mixed phase or composite ternary sulfide materials, the CTS NPs presented herein show a better performance. In a full cell device using LiCoO 2 (LCO) as cathode, a good performance is achieved as well with an energy density of 405 Wh/Kg at 0.1 A g À 1 . V-10 mA battery tester. The impedance and cyclic voltammetry were performed with VMP3 biologic system equipped with potentiostat and galvanostat channels.
