Cu 2 SnS 3 (CTS), as a potential thermoelectric (TE) material, the electrical and thermal transport properties are heavily determined by its original phase structure and the following phase evolution upon heating. Unlike previous studies that induced CTS phase transition by doping, this study used mechanical alloying powder as the precursor and successfully prepared phase-pure cubic (c-) and monoclinic (m-) CTS samples, as well as two-phase mixed samples with different percentage composition of c-CTS and m-CTS, by simply adjusting the hot pressing temperature. Firstly, phase structures of hot-pressed specimens were determined and confirmed by XRD refinement, SEM, TEM, and Raman spectroscopy. Secondly, thermodynamic property was analysis by DSC analysis, and phase evolution was detailed by analyzing specimens quenched at various temperatures. Then, the electrical and thermal transport properties were measured up to 500 °C, and were correlated with phase evolution analyzed above. Benefiting from cationic disorder, a maximum zT of 0.42 at 500 °C was achieved in c-CTS samples hot-pressed at 575 °C. The phase evolution of CTS was comprehensively investigated by using high-quality samples. The results indicate that phase transition is the potential mechanism for the doping effect in most studies, providing some guidance for improving the performance of environmentally friendly TE sulfides.

Cu 2 SnS 3 , recognized as a conversion and alloy type anode material for lithium-ion batteries, possesses a high theoretical specific capacity of 784 mAh g −1 and exhibits a distinct lithium storage mechanism. However, its intrinsically low electrical conductivity and pronounced volume expansion during cycling pose significant challenges to its practical battery performance. To address these limitations, Cu 2 SnS 3 @C (CTS@C) nanomaterials were synthesized by a one-step microwave-assisted method, utilizing ethylene glycol as a solvent and glucose as a carbon precursor. The incorporation of a carbon coating has been demonstrated to markedly improve the conductivity of the material and mitigate the volume expansion associated with lithium insertion and extraction. Electrochemical tests revealed that the CTS@C electrode exhibits superior electrochemical performance. Specifically, the CTS@C electrodes exhibited an initial discharge capacity of 612.8 mAh g −1 , with a retention of 295.8 mAh g −1 after 500 cycles at a current density of 500 mA g −1 . The carbon coating not only effectively enhances the conductivity of the electrode material, but also accelerates the electrochemical reaction rate, and enhances the diffusion rate of lithium ions, thereby significantly improving the electrochemical performance of the battery.

Cu2SnS3 is considered as an emerging potential candidate for electrode materials due to considerable interlayer spaces and tunnels in its crystal structures and excellent conducting ability. Ternary Cu2SnS3 as anode in lithium ion batteries has already been reported, but it is rarely mentioned to be applied in supercapacitors which is considered to be a complementary energy storage device for lithium ion batteries. It is an effective method to improve the electrochemical performance of materials by adjusting the morphology and microstructure of materials. In present study, ternary nanosheet-assembled Cu2SnS3 microspheres (M-CTS) and nanoparticles-like Cu2SnS3 (N-CTS) are synthesized via a facile solvothermal route. The results suggest that Cu2SnS3 microspheres (M-CTS) exhibit better capacitive performance compared with Cu2SnS3 (N-CTS) nanoparticles, which means that morphology does have a significant effect on the electrochemical reaction. M-CTS presents excellent supercapacitor performances with the high specific capacity of about 406 C g–1 at a current density of 1 A g–1 and achieves a high energy density of 85.6 W h kg–1 and power density of 720 W kg–1. The remarkable electrochemical performance of Cu2SnS3 can be attributed to the large specific surface area, smaller average pore size, and improved electrical conductivity. Our research indicates that it is very suitable for large-scale production and has enormous potential in the practical application of high-performance supercapacitors.

Graphical A facile hydrothermal method is employed to prepare Cu 2 SnS 3 /reduced graphene oxide (CTS/RGO) composites. Contrary to the bare CTS particle, the CTS/RGO composite exhibits better sodium-storage properties. The improved electrochemical performances are ascribed to the unique structure with anchoring ultrafine CTS nanoparticles on the surface of high conductive and flexible RGO sheets, which can enhance the reaction kinetics and alleviate the volume effect of the active materials during the sodiation/desodiation process. Ternary Sn-based sulfides have been considered as potential anode materials for sodium-ion batteries (SIBs) due to their unique composition and high theoretical specific capacities. However, such kind of materials suffers from sluggish kinetics and huge volumetric variation resulting from the large ionic size of the sodium ions during the battery operation process. Herein, we use a facile hydrothermal method to prepare Cu 2 SnS 3 /reduced graphene oxide (CTS/RGO) composite. Characterizations reveal that CTS/RGO consists of ultrafine CTS nanoparticles with uniform and small size, which are anchored uniformly on the surface of RGO sheets. Benefited from the unique structure feature, CTS/RGO has a high reversible capacity of 566.8 mA h g −1 , good cycle stability and rate capability even at a high current density of 3200 mA g −1 , which is superior to that of bare CTS. The improved performances are ascribed to the unique structure with anchoring ultrafine CTS nanoparticles on the surface of high conductive and flexible RGO sheets, which can greatly enhance electrochemical reaction kinetics and effectively alleviate volume effect of the active materials.

In recent years, there is significant interest in Cu 2 SnS 3 (CTS) thin film solar cells owing to the eco-friendly nature and abundant elemental composition. However, the efficiency prepared in laboratory settings for these solar cell remains relatively low, primarily due to serious open-circuit voltage losses. Cation substitution is one of the strategies to alleviate this problem. In this work, Ag and Ge dual-cation substitution in CTS is proposed, which occupy partial Cu and Sn lattice sites respectively. Investigation reveals that substituting Cu with part Ag increases the band gap slightly, promotes grain growth, and improves crystallinity of CTS films. Simultaneously, Ge incorporation shifts the conduction band upwards to some extent, while reducing grain boundaries, due to increasing the grain size. As a result, the incorporation of 6 % Ag resulted in an optimal efficiency (PCE) of 2.78 %. Furthermore, employing dual-cation substitution with 6 % Ag and 6 % Ge is employed, the CTS device achieved an optimal efficiency of 3.15 %. This work develops the synergistic effect of Ag and Ge dual-cation substitution in CTS device and confirms that this approach can improve device performance, thus providing new research ideas for advancing the development of CTS device.

Cu 2 SnS 3 (CTS) based thin film solar cells were successfully fabricated through a facile solution processes followed by a post-sulfurization treatment. The influence of sulfurization temperature and time on the structural, compositional, morphological, optical and also the electrical properties of the solar cells were systematically studied. The results showed that the CTS thin films sulfurized at 580 °C would be a void-free and densely packed absorber layer with the grain size to be microns, having the band gap of ~ 1.01 eV. Furthermore, the sulfurization time is the key factor to influence the electronic properties of CTS absorber layer, and thus resulting in the best device performance of PCE = 2.41% by 20 min sulfurization process.

Hypothesis Despite that the development of Cu 2 SnS 3 (CTS) catalyst has attracted increasing interests, few study has reported to investigate its heterogeneous catalytic degradation of organic pollutants in a Fenton-like process. Furthermore, the influence of Sn components towards Cu (II)/Cu (I) redox cycling in CTS catalytic systems remains a fascinating research. Experiments In this work, a series of CTS catalysts with controlled crystalline phases were prepared via a microwave-assisted pathway and applied in the H 2 O 2 activation for phenol degradation. The efficiency of phenol degradation in CTS-1/H 2 O 2 system (CTS-1: the molar ratio of Sn (copper acetate) and Cu (tin dichloride) is determined to be Sn:Cu = 1:1) was systematically investigated by controlling various reaction parameters including H 2 O 2 dosage, initial pH and reaction temperature. We discovered that Cu 2 SnS 3 exhibited superior catalytic activity to the contrast monometallic Cu or Sn sulfides and Cu (I) acted as the dominant active sites. The higher Cu (I) proportions conduce to the higher catalytic activities of CTS catalysts. Quenching experiments and electron paramagnetic resonance (EPR) further proved that the activation of H 2 O 2 by CTS catalyst produces reactive oxygen species (ROS) and subsequently leads to degradation of the contaminants. A reasonable mechanism of enhanced H 2 O 2 activation in Fenton-like reaction of CTS/H 2 O 2 system was proposed for phenol degradation by investigating the roles of copper, tin and sulfur species. Findings The developed CTS acted as a promising catalyst in Fenton-like oxidation progress for phenol degradation. Importantly, the copper and tin species contribute to a synergetic effect for the promotion of Cu (II)/Cu (I) redox cycle, which thus enhanced the activation of H 2 O 2 . Our work may offer new insight on the facilitation of Cu (II)/Cu (I) redox cycle in Cu-based Fenton-like catalytic systems.

Ternary Cu 2 SnS 3 (CTS) is a promising material for thin-film solar cells because it consists of nontoxic and earth-abundant elements. The present paper reports the preparation of monoclinic CTS thin films by a sol–gel solution-based method. The effects of the Cu/Sn atomic ratio on the structure and morphology were investigated. As the atomic ratio of Cu/Sn varied from 1.6 to 2.0, the compactness of the CTS films improved; furthermore, secondary phases, such as SnS, gradually disappeared; and the grain size of the films decreased. The CTS film with a Cu/Sn ratio of 1.9 showed a monoclinic structure with homogeneous morphology and a band gap of 1.12 eV, yielding a power conversion efficiency of 0.58%. These results could pave the way for the development of CTS thin-film solar cells.

Peroxymonosulfate (PMS)-assisted photocatalytic degradation represents an efficient advanced oxidation process for water purification. In this study, a novel SrTiO₃/Cu₂SnS₃ heterojunction was synthesized via a hydrothermal method, which was employed for visible-light-driven PMS activation to degrade norfloxacin (NOR). The STO/CTS-2 (n SrTiO₃ /n Cu₂SnS₃ = 2) composite exhibited superior catalytic performance, achieving 92.65% NOR degradation within 60 min, attributed to enhanced charge separation and efficient PMS activation. Comprehensive characterization confirmed the heterostructure formation, optimized band alignment, and improved light absorption. Radical trapping experiments revealed that superoxide radicals (•O₂⁻) dominated the degradation process, with additional contributions from SO 4 •⁻ , •OH, 1 O 2 , and h⁺. A plausible NOR degradation pathway and the underlying PMS activation mechanism were proposed. This study provides new insights into visible-light-driven PMS activation and presents an effective strategy for antibiotic wastewater treatment.

In this paper, we report a solution method to fabricate Cu 2 SnS 3 thin films without involving post sulfurization. The effects of thiourea/metal radios in the precursor solution and the annealing temperatures on the structural, compositional and optical properties of Cu 2 SnS 3 thin films were investigated. The results of X-ray diffraction patterns, Raman spectroscopy and field-emission scanning electron microscopy indicate that the S-rich condition is preferred to suppress the growth of secondary phase Cu 4 SnS 4 . Furthermore, to avoid the over evaporation of volatile SnS, a medium annealing temperature was proved critical to obtain phase-pure Cu 2 SnS 3 film. The UV–Vis spectroscopy shows the excellent absorption behavior in the visible light region for Cu 2 SnS 3 prepared at the annealing temperature of 540 °C with the thiourea/metal ratio of 6, which corresponds to a direct band gap of ~1.02 eV.

Ternary copper tin sulfide (Cu–Sn–S) compounds have been investigated for decades as promising candidates of earth-abundant thin film solar cell absorbers. Cu 2 SnS 3 is a representative member of this material system, and is highly expected to be a potential thermoelectric material by the first-principles calculations. In this work, Cu 2 SnS 3 bulk materials were synthesized by the mechanical alloying (MA) combined with spark plasma sintering (SPS), and their crystal structures, electronic transport properties and enhanced thermoelectric performance were systematically investigated. We found that pristine Cu 2 SnS 3 is a p-type thermoelectric material with a relatively high thermopower up to 300 μV/K and low thermal conductivity below 1.0 W/m K above 700 K. It revealed that In doping is an effective means to improve the electrical transport properties, which leads to a figure of merit ( ZT ) of Cu 2 Sn 0.9 In 0.1 S 3 close to 0.6 at the relatively low temperature (773 K).
