Two new pentanary sulfides Ba3La4Ga2Sb2S15 (1) and BaLa3GaSb2S10 (2) have been discovered by high temperature solid state reactions. Ba3La4Ga2Sb2S15 features a new zero-dimensional structure type, which consists of unique isolated Sb2S7 dimers and GaS4 tetrahedra. In contrast, with less GaS4 tetrahedra in the formula, BaLa3GaSb2S10 forms a one-dimensional structure which is constructed by teeter-totter (SbS4)n chains and isolated GaS4 tetrahedra. On the basis of UV/Vis spectroscopy, their band gaps are determined to be 2.42 and 2.15 eV, respectively, which are much wider than that of analogue La4FeSb2S10 (1.0 eV). In addition, theoretical studies illustrate the important role of Ga in expanding the band gaps with respect to Fe atoms. The calculated crystal orbital Hamilton population and electron localization function confirm that the long Sb–S bonds in Ba3La4Ga2Sb2S15 (2.932(2) Å) and BaLa3GaSb2S10 (3.216(5) and 3.219(5) Å) have weak but nonnegligible bonding interactions.

This work proposes a novel nitrogen bottom-blowing method to enhance mass transfer in the molten salt electrolysis process, improve current efficiency, and reduce electrolysis energy consumption. The effect of nitrogen agitation on the dissolution of Sb 2 S 3 and Sb was studied. The effects of nitrogen flow rate, electrolytic temperature, cell voltage, and pole spacing on the distribution behavior of Sb during constant piezoelectric reduction were investigated. The results show that nitrogen agitation can obviously accelerate the dissolution of Sb 2 S 3 . The current efficiency of the cathode reaches 92.76%, the energy consumption is 1.78 kWh kg −1 , and the grade of crude antimony is 98.5%. Compared to no nitrogen stirring, electrolytic current efficiency is improved by 19.87% and the energy consumption is saved by 20.89%. Furthermore, the appropriate flow rate of nitrogen accelerates the removal of sulfur from the reactor and avoids the formation of high-priced antimony compounds.

Advanced thermal batteries require new cathode materials with high thermal stability, high capacity, high voltage, and high-rate performance. Although antimony sulfide (Sb 2 S 3 ) has a high theoretical capacity, its low melting point characteristic hinders the application in thermal batteries. Here, we demonstrate that modifying with a small amount of graphite can effectively immobilize liquid Sb 2 S 3 to form a pellet electrode, which allows us to use cathodes made of this liquid active material just like traditional solid-state electrodes. The formation of such a solid-like liquid cathode can be attributed to graphite's affinity for Sb 2 S 3 while repelling the molten electrolyte. The electrochemical testing in LiCl-KCl eutectic at 560 °C and 600 °C indicates that, the performance of the graphite modified Sb 2 S 3 (gra@Sb 2 S 3 ) of optimized proportions far surpasses that of traditional FeS 2 , both in terms of discharge capacity and thermal stability. This study provides a strategy for developing new kind of liquid cathode materials for high-performance thermal batteries.

Sb2S3 dendrites composed of 1-dimensional rods were prepared by a facile solvothermal reaction. The dosage of the poly(acrylic acid) (PAA) morphology-controlling reagent and the reaction temperature are key factors determining the final morphology of the product. Temporal experiments revealed that the formation of Sb2S3 dendrites experienced successive stages including precipitate reaction, crystallization and tip splitting. The as-prepared Sb2S3 dendrites were further employed as sensing material for electrochemical detection of dopamine (DA). A cyclic voltammogram (CV) showed that an Sb2S3 dendrite modified electrode enables the selective electro-oxidation of DA in the presence of ascorbic acid (AA). The constructed biosensor demonstrated a linear response range of 0.125–160 μM and a detection limit of 0.1 μM, which suggests that the Sb2S3 dendrites are promising sensing materials in the electrochemical analysis of DA.

Three types of Sb 2 S 3 with different degrees of crystallinity were synthesized via a hydrothermal procedure by adjusting the concentration of hydrochloric acid . The amorphous Sb 2 S 3 sample (A-Sb 2 S 3 ) exhibited nearly 13 times higher photocatalytic activity for the decolorization and biodegradability improvement of MO solution compared with both crystalline samples under visible light (λ > 420 nm). It was verified that MO and Congo Red azo dyes were adsorbed onto A-Sb 2 S 3 by displacing hydroxyl groups (OH − ) to complex with Sb 3+ on A-Sb 2 S 3 , which occurred via σ bonding to the lone pairs of azo nitrogen atoms with Sb 3+ (σ-Sb-( N N )). Moreover, the decolorization rate of MO was positively related to its adsorption onto A-Sb 2 S 3 , and no significant degradation was observed for non-azo intermediates. The predominant photodegradation pathways of MO were reduction and oxidization to sulfanilic acid, NO 3 − and small-molecule acids. On the basis of photoelectron spectra, ESR (Electron spin resonance) measurements and other experimental information, it was proposed that the complexes (σ-Sb-( N N )) could transmit photogenerated electrons and holes to the azo group, breaking the N N bond, causing azo dye decolorization to improve their biodegradability; while on the surface of bare A-Sb 2 S 3 , the strong coordination interaction of OH − with Sb 3+ made OH − groups become the recombination centers for photogenerated electrons and holes during the photocatalytic reaction.

Sodium-ion batteries (SIBs) is a promising alternative for lithium-ion batteries (LIBs) due to abundant resources and low cost. Herein, a series of composites, CDC/SbSxx (xx means weight content of Sb 2 S 3 ), composed from catkin derived carbon (CDC) material, possessing tube-like morphology, and Sb 2 S 3 fine particles prepared by solvothermal method were selected as anodes for SIBs. The electrochemical property results demonstrated that the CDC/SbSxx electrodes afforded improved cycling stability and enhanced rate performance due to the higher Sb 2 S 3 particle retention ability and improved electric conductivity . Furthermore, the content of Sb 2 S 3 played in important role in electrochemical performance. The CDC/SbS15 composite electrode accommodated a higher Sb 2 S 3 content (16.8 wt%) and exhibited improved discharge capacity and excellent cycling performance even at a high current density. Given the cost effectiveness and material sustainability, this work provides a potential strategy to develop low-cost and sustainable composite anode for advanced SIBs.

Antimony sulfide (Sb 2 S 3 ) is emerging as a popular photovoltaic candidate for thin-film solar cells due to its large absorption coefficient, suitable bandgap, nontoxic, and earth-abundant nature. The performance of thermally evaporated Sb 2 S 3 devices is severely restricted by interfacial recombination leading to high open-circuit voltage ( V OC ) losses. CdS as electron transport layer (ETL) has overcome this problem, but triggered lower J SC issues due to parasitic absorption loss conceding to its smaller bandgap. Herein, a spray pyrolysis method is adopted for the deposition of a uniform and compact Zn-doped TiO 2 film with tuned energy levels to facilitate charge extraction and transport. The solar cell fabricated with a modified TiO 2 ETL holds superior interface quality, high build-in potential, and suppressed recombination losses, therefore pronouncedly improves the V OC . As a result, the efficiency of the device is boosted from 4.41% to 5.16%, a record V OC of 702 mV for Cd-free full-inorganic Sb 2 S 3 solar cell is achieved. These findings are expected to be implemented in other Sb-chalcogenide solar cells to further enhance the device performance.

Efficient planar antimony sulfide (Sb2S3) heterojunction solar cells have been made using chemical bath deposited (CBD) Sb2S3 as the absorber, low-temperature solution-processed tin oxide (SnO2) as the electron conductor and poly (3-hexylthiophene) (P3HT) as the hole conductor. A solar conversion efficiency of 2.8% was obtained at 1 sun illumination using a planar device consisting of F-doped SnO2 substrate/SnO2/CBD-Sb2S3/P3HT/Au, whereas the solar cells based on a titanium dioxide (TiO2) electron conductor exhibited a power conversion efficiency of 1.9%. Compared with conventional Sb2S3 sensitized solar cells, the high-temperature processed mesoscopic TiO2 scaffold is no longer needed. More importantly, a low-temperature solution-processed SnO2 layer was introduced for electron transportation to substitute the high-temperature sintered dense blocking TiO2 layer. Our planar solar cells not only have simple geometry with fewer steps to fabricate but also show enhanced performance. The higher efficiency of planar Sb2S3 solar cell devices based on a SnO2 electron conductor is attributed to their high transparency, uniform surface, efficient electron transport properties of SnO2, suitable energy band alignment, and reduced recombination at the interface of SnO2/Sb2S3.

Sodium-ion batteries (SIBs) are usually considered as a promising alternative to lithium-ion batteries due to the abundant resources of sodium. Antimony has been widely used for SIBs anodes because of its high capacity, which often suffers the issue of unstable structure, leading to a poor performance and unstable solid electrolyte interface (SEI). In order to improve the stability of anodes, the electrochemical reduction of solid antimony sulfide/carbon nanotubes (Sb 2 S 3 /CNTs) to a antimony/carbon nanotubes (Sb/CNTs) composite used as an anode for SIBs using deep eutectic solvent is reported for the first time. The electrolytic Sb particles will be wrapped by the CNTs after the electrochemical desulfurization approach, resulting in an improvement of the stability of the electrolytic products used for anodes. The electrolytic Sb/0.5CNTs anode exhibits a high specific capacity of 612.3 mAh g −1 after 200 cycles at a current density of 0.1 A g −1 , and a high specific capacity of 480.9 mAh g −1 after 150 cycles at a current density of 0.5 A g −1 . The results demonstrate the feasibility of the direct electrochemical desulfurization strategy from solid sulfides and provide a novel route for producing SIBs anodes.

Antimony sulfide (Sb 2 S 3 ) has great potential as a promising wide–bandgap, low–cost, low–toxicity, and stable photovoltaic material for next–generation indoor and tandem photovoltaic applications. This article reports that there are competitive chemical reaction mechanisms during hydrothermal preparation of Sb 2 S 3 , and we present an effective strategy to control these mechanisms using the anionic surfactant sodium dodecyl sulfate (SDS) as a reaction additive. We found that the SDS additive significantly enhances the hydrothermal heterogeneous reaction path and thus improves the quality of the Sb 2 S 3 absorber by shifting the balance between homogeneous and heterogeneous reactions. An efficiency of 6.84% under standard AM1.5 illumination irradiance is achieved. The SDS–optimized Sb 2 S 3 solar cells also show remarkably high indoor photovoltaic performance. An efficiency as high as 16.37% is reported under indoor illumination by a 1000 lx white light LED source. This result indicates the excellent prospects of Sb 2 S 3 in a broad range of photovoltaic applications.

Antimony sulfide (Sb2S3) stands out as an exemplary material for the light-absorbing layer in solar cells, attributed to its favorable light absorption properties, eco-friendliness, and robust stability. However, undesirable [hk0] crystal orientation and the presence of pinholes will degrade film quality and device performance. Here, an in situ polymerization-assisted grain growth strategy was introduced by adding monomer acrylic acid (AA) to the growth solution during the chemical bath deposition (CBD) process of Sb2S3. At the initial stage, AA serves as a complexing agent, coordinating with Sb3+ ions to mitigate particle agglomeration in the solution, which not only enhances the film quality but also ensures a more desirable [hk1] crystal orientation. During the reaction, in situ synthesized poly(acrylic acid) (PAA) builds coordination bonds with Sb3+ through the carboxyl groups, inducing the cross-linking of Sb2S3 grains. This cross-linking yields compressive constraints and reduces the number of pinholes in the Sb2S3 films, culminating in improved film quality and reinforced device steadiness. Consequently, the best power conversion efficiency (PCE) of the AA-modified Sb2S3 solar cell reached 7.12% (compared to 6.70% for the control), Furthermore, incorporating an additional SnO2 electron transport layer and a BTR-TPA interfacial layer bolstered the efficiency to 7.51%.

Antimony sulfide (Sb 2 S 3 ) has been applied in photoelectric devices for a long time. However, there was lack of information about Sb 2 S 3 quantum dots (QDs) because of the synthesis difficulties. To fill this vacancy, water-soluble Sb 2 S 3 QDs were prepared by hot injection using hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) mixture as anionic-cationic surfactant, alkanol amide (DEA) as stabilizer, and ethylenediaminetetraacetic acid (EDTA) as dispersant. Photoelectric properties including absorbing and emission were characterized by UV-Vis-IR spectrophotometer and photoluminescence (PL) spectroscopic technique. An intensive PL emission at 880 nm was found, indicating Sb 2 S 3 QDs have good prospects in near-infrared LED and near-infrared laser application. Sb 2 S 3 QD thin films were prepared by self-assembly growth and then annealed in argon or selenium vapor. Their band gaps ( E
g
s) were calculated according to transmittance spectra. The E
g
of Sb 2 S 3 QD thin film has been found to be tunable from 1.82 to 1.09 eV via annealing or selenylation, demonstrating the good prospects in photovoltaic application.
