Photodetectors (PDs) for weak light signal detection have wide applications for optical communication and imaging. Antimony sulfide (Sb2S3) as a nontoxic and stable light-sensitive material becomes a promising candidate for weak light PDs, which are developing in the direction of high response, high speed, and low cost. Herein, a self-powered Sb2S3 PD with the structure of FTO/TiO2/Sb2S3/Au is developed to achieve weak light detection for 300–750 nm visible light. We control the Sb2S3 thickness with about 460 nm to match depletion region width (438 nm) and obtain an excellent photoresponsivity and 3 dB bandwidth. Furtherly, we prepare pyramid structure polydimethylsiloxane (PDMS) on the illuminating surface to enhance the performance of weak light detection by light-trapping effects. The photocurrent of Sb2S3 PD with 20 μm-sized PDMS texture achieves 13.6% improvement compared with the control one. Under weak 530 nm light illumination of 1 μW cm–2, the self-powered Sb2S3 PD with PDMS achieves high responsivity (3.41 A W–1), large detectivity (2.84 × 1013 Jones), and ultrafast speed (15 μs). The present Sb2S3 PD and light-trapping strategy are expected to provide an alternative to future commercial weak light detection applications.

Antimony sulfide (Sb 2 S 3 ) with a 1D molecular structure has strong bending characteristics, showing great application potential in flexible devices. Herein, the flexible substrate-structured Sb 2 S 3 solar cells is developed and improve device performances by the back interface selenization. The high-quality Sb 2 S 3 film with an optimal thickness of 1.8 µm, ensuring efficient spectra utilization, is deposited on flexible Mo foils by the rapid thermal evaporation technique. To solve the issues of back interfacial recombination and charge transport, the 20 nm MoSe 2 layer between Sb 2 S 3 film and Mo foil is fabricated by substrate selenization in the tube furnace. Further investigations indicate that the MoSe 2 layer improves the interfacial energy band alignments and induces the [hk1] orientation of Sb 2 S 3 film, thereby passivating defects and enhancing the carrier transport capacity. The flexible solar cell in the structure of Mo foil/MoSe 2 /Sb 2 S 3 /CdS/ITO/Ag, exhibiting good flexibility to stand thousands of bending, achieves an efficiency of 3.75%, which is the highest for Sb 2 S 3 devices in substrate configuration. The presented flexible structure and back interfacial selenization study will provide new prospects for inorganic Sb 2 S 3 thin film solar cells.

Sodium-ion batteries with potentially low cost is an alternative to lithium-ion batteries for large-scale energy storage. However, developing high energy density and ultralong cycle life electrodes for sodium-ion batteries is a key issue due to the larger radius of Na + than Li + and the sluggish sodium intercalation kinetics. One-step electrospinning process has been applied to synthesis Sb 2 S 3 nanocrystals hosted in multichannel porous N-doped carbon nanofiber (CNF). Sb 2 S 3 nanoparticles with diameter of 10–50 nm were uniformly embedded in CNF, while the multichannel pores of CNF act as a buffer to restrict the volume expansion of Sb 2 S 3 during cycling. Sb 2 S 3 @N-doped carbon nanofiber (Sb 2 S 3 @CNF) delivered a specific capacity of 311 mAh g −1 at 100 mA g −1 with a capacity retention of 87% after 1000 cycles at 1A g −1 , corresponding to a capacity decay rate of only 0.013% per cycle. Benefited from the unique multichannel mesoporous structure, charge storage of Sb 2 S 3 @CNF is mainly contributed by a surface capacitive process indicating significantly enhanced mass diffusion properties. The as-developed nanofibers with a cylindrical porous structure by a one-step electrospinning method can be an excellent host for electroactive materials to achieve ultralong cycle life.

In this paper, the modified molecular interaction volume model (M-MIVM) was used to calculate the activities of components of the PbS–Sb 2 S 3 binary matte system. On this basis, the vapor-liquid equilibrium (VLE) data of the PbS–Sb 2 S 3 system were calculated by M-MIVM in combination with the theory of vacuum metallurgy and VLE. Additionally, the VLE experiment of the PbS–Sb 2 S 3 binary matte system was conducted to correctly interpret the results of the model. The calculated results of the VLE of the model were consistent with the experimental values, and the VLE calculation of the PbS–Sb 2 S 3 binary matte system by M-MIVM was reliable. This is an effective and convenient method to predict the relationship between product components with temperature and pressure in vacuum distillation of PbS and Sb 2 S 3 mixed melts, providing theoretical guidance for vacuum separation and purification of PbS and Sb 2 S 3 .

Compositing a secondary phase in Ag 2 Se can usually tune the electron and phonon scattering to improve the thermoelectric performance. However, the intrinsically high carrier concentration still limits the performance optimization. Here, we employ a modulation decoration strategy to simultaneously achieve submicron-scale constituents and compositional modification for synergistic optimization of thermoelectric properties . Amorphous nano Sb 2 S 3 has been decorated on the surface of Ag 2 Se powders, and S was added into the Ag 2 Se matrix through an ion exchange reaction accompanied by the formation of a crystal/amorphous mixed secondary phase of Sb 2 (S, Se) 3 . The S doping reduced the excessive intrinsic carrier concentration, leading to modified electrical transport properties and significantly reduced electrical thermal conductivity. On the other hand, introducing the S dopants and the crystal/amorphous interfaces into the Ag 2 Se matrix could increase the lattice anharmonicity, further contributing to the reduced thermal conductivity. Consequently, the Ag 2 Se-0.4 % Sb 2 S 3 sample obtains a high average zT value of > 1 in the temperature range of 300–390 K. In addition, the maximum cooling temperature difference of over 85 K can be predicted in an Ag 2 Se/Ag 2 Se-0.4 % Sb 2 S 3 segregated module at the hot side temperature of 350 K.

Antimony sulfide (Sb 2 S 3 ) thin film is a promising light absorber for solar cell application due to its suitable bandgap, high absorption coefficient, and non-toxic constituents. However, thermally evaporated Sb 2 S 3 thin films experience sulfur loss during evaporation and post-annealing, which do harm to the film quality and the performance of the devices. In this work, for the first time Sb 2 S 3 thin films are prepared by thermally evaporating antimony pentasulfide (Sb 2 S 5 ) precursor. The thermal and microstructural properties of Sb 2 S 3 and Sb 2 S 5 precursors are studied and compared. The crystallization of the Sb 2 S 3 film (S-5) prepared from Sb 2 S 5 precursor is inferior to that (S-3) from Sb 2 S 3 powder. And the annealed S-5 film shows a larger bandgap of 1.69 eV than S-3. However, compared with S-3, planar S-5 thin film solar cells in the configuration of glass/(SnO 2 :F) FTO/TiO 2 /Sb 2 S 3 /Spiro-OMeTAD/Ag exhibit an apparently improved photovoltaic performance, with the best power conversion efficiency of 3.75% and high fill factor of 0.56, which is the highest efficiency of thermally evaporated planar Sb 2 S 3 solar cell. The capacitance–voltage ( C–V ) measurement indicates that this might come from the higher C–V derived space-charge density in S-5. This work offers a new method to prepare Sb 2 S 3 thin films for efficient solar cells.

The Sb 2 S 3 anode materials with high theoretical capacity were troubled by their sluggish electrochemical kinetics and huge volume expansion in sodium-ion batteries. Herein, we firstly designed a unique Sb 2 S 3 @nitrogen-doped carbon (Sb 2 S 3 @N-C) nanotube encapsulated by porous graphene aerogel to solve the above technical barrier. The composite aerogel with ingenious structure was creatively designed by coating polydopamine (PDA) onto the Sb 2 S 3 nanorods. The PDA was not only a precursor of nitrogen-doped carbon (N-C) layer adjusting volume change of Sb 2 S 3 during storage Na + but also acted as a reducing agent assisting to create graphene aerogel. Moreover, the formation of unique Sb 2 S 3 @N-C coaxial nanotubes was facilitated by the N-C layer, which triggered the strong interaction between the Sb 2 S 3 and graphene to maintain structural integrity. Importantly, the composite aerogel synergized the superior electrical conductivity, abundant porous channels, and excellent electrochemical reactivity into one. As a result, the optimized anode exhibited high reversible capacity, superior rate capability, and impressively cycling stability. Furthermore, the full cell was constructed from the optimized composite aerogel anode and Na 3 V 2 (PO 4 ) 3 cathode, exhibiting a high reversible capacity of 388 mA h g −1 at 0.1 A g −1 with a remarkable energy density of 189 Wh kg −1 .

We found that the morphology of nanowires could be regulated by adding polyvinylpyrrolidone (PVP, K30) in hydrothermal synthesis of antimony sulfide (Sb 2 S 3 ) nanowires. The nanowires with length more than 20 μm were obtained by adding the proper amount of PVP. Three kinds of fully nanostructured photodetector using Sb 2 S 3 nanowires as active regions were fabricated and the first detector used silver nanowires as the electrodes at both ends, the second used silver nanowires as one electrode and MXenes as the another electrode, and the third used MXenes as both electrodes. The light response speed of the photodetector with both MXenes electrodes was improved greatly. The photodetector which used MXenes and silver nanowires as electrodes at two ends, respectively, showed the phenomenon of being self-driven. The mechanism of asymmetric hole migration was put forward to explain the effect of being self-driven.

Poor reversibility of conversion and alloying reactions for Sb 2 S 3 limits its application as high capacity anode for rechargeable lithium storage. Herein a facile high-efficiency plasma assisted milling (P-milling) was used to create Sb 2 S 3 -C hybrid nanostructure with disk-like Sb 2 S 3 nanograins wrapped within ultrathin graphite nanosheets . Benefiting from the high structure stability and excellent Li + ion diffusion kinetics in the graphite wrapped Sb 2 S 3 nanostructure , highly reversible conversion and alloying reactions are maintained throughout the long-term cycles. The Sb 2 S 3 -C nanocomposite anode demonstrates a high stable capacity of 638.2 mA h g −1 after 250 cycles at 200 mA g −1 between 0.01 and 3.0 V vs. Li/Li + , with a high initial Coulombic efficiency of 78.3%. A reversible capacity of 496.1 mA h g −1 is obtained after 500 cycles even at higher current rate of 1 A g −1 , much superior to those of the unmilled Sb 2 S 3 -C and P-milled Sb 2 S 3 anodes. These demonstrate that P-milling could be a promising strategy to create high performance metal chalcogenide anode materials involved both conversion and alloying reactions toward lithium storage.

In this study, Sb2S3/In2S3/TiO2 (SIT) heterojunction photocatalysts were prepared by a simple two-step hydrothermal method and applied to the photocatalytic degradation of levofloxacin (LEV). After 160 min of reaction under visible light, the SIT heterojunction photocatalyst degraded 10 mg L−1 LEV at a rate of 86.7%. The degradation of LEV follows pseudo-first-order kinetics with a rate constant 1.16 × 10−2 min−1, which is 1.42, 1.22 and 1.05 times higher than that of TiO2, SI and IT, respectively. Meanwhile, the SIT photocatalysts also showed high photocatalytic activity for other antibiotics. The enhanced photocatalytic activity of the ternary heterostructures was attributed to the full-spectrum response and the synergistic effect of the dual Z-type heterojunctions, which improved the visible light absorption and facilitated the charge separation. In addition, ˙OH and ˙O2− play a dominant role in the photodegradation process. This work contributes to the design of novel photocatalytic materials with dual Z-type heterojunctions and efficient photocatalysts for the degradation of antibiotics.

Antimony sulfide (Sb2S3) has emerged as a promising photoactive material due to its high light absorption capability. However, the organic Spiro-OMeTAD hole transport layer (HTL) poses a severe challenge to highly efficient Sb2S3 solar cells because of its high cost and poor stability. To address these issues, a MnS–PbS composite HTL was fabricated via the coevaporation process for the first time. By tuning the MnS:PbS ratio, the microstructure, carrier transport, and energy band alignment at the Sb2S3/ MnS–PbS interface were optimized. The high carrier mobility of PbS films and the high carrier concentration of MnS films enabled the MnS–PbS composite HTL possessing the superior conductivity. Devices employing the optimized MnS–PbS HTL achieved a champion power conversion efficiency of 6.60%, with significant improvements in short-circuit current, fill factor, and photostability due to the enhanced hole transport, suppressed recombination, and reduced photocurrent loss. This facile coevaporated composite HTL demonstrates a significant potential for efficient fully inorganic Sb2S3 solar cells.

Facile synthesis methods and rich-reserve feedstocks are the keys to accelerating the scale commercial use of Sb-based anodes for sodium-ion batteries (SIBs). In this paper, we synthesize Sb/carbon nanotubes (CNTs) composite anodes by a straightforward electrochemical approach using stibnite and CNTs as feedstocks. The concentrated sodium hydrate solution profits the formation of antimony and electrons enables the solid-state electrochemical desulfurization . The low-cost stibnite can be directly obtained from the earth's crust avoiding the intermediate processes and pollution of preparing the common-used raw materials SbCl 3 and metallic Sb. CNTs provides a network for both electron and ion transport, thereby resulting in producing Sb particles anchored in the CNTs network as well as restraining the cluster of electrolytic Sb particles. The electrolytic Sb-0.5CNTs anode delivers a decent capacity of 510 mAh g −1 at 0.1 A g −1 after 200 cycles and even 425 mAh g −1 at 1 A g −1 over 100 cycles. The excellent sodium-storage performances are attributed to the unique structure of the electrolytic Sb/CNTs composite. This electrochemical desulfurization method can be expanded to prepare other metal-carbon type anodes from metal sulfides ores and carbon materials composites.
