We prepared antimony metal films via electrodeposition, followed by the synthesis of Sb2S3films through a chemical vapor phase reaction. Finally, an Sb2O3film was deposited onto the Sb2S3film using a chemical bath method, successfully constructing a heterojunction photocathode of Sb2S3/Sb2O3; the synthesized Sb2S3/Sb2O3heterojunction is classified as a Type I heterostructure. The resulting Sb2S3/Sb2O3heterojunction exhibited a photocurrent density of −0.056 mA cm−2at −0.15 V (vs. RHE), which is 1.40 times higher than that of Sb2S3alone under simulated solar illumination. Additionally, the Sb2S3/Sb2O3heterojunction demonstrated a lower carrier recombination rate and a faster charge transfer rate compared to Sb2S3, as evidenced by photoluminescence and electrochemical impedance spectroscopy tests. For these reasons, the Sb2S3/Sb2O3heterojunction obtained a hydrogen precipitation rate of 0.163mL cm−2h−1, which is twice the hydrogen precipitation rate of Sb2S3, under the condition of 60 min of light exposure. The significant enhancement in photoelectrochemical performance is attributed to the formation of the Sb2S3/Sb2O3heterojunction, which improves both carrier separation and charge transfer efficiency. This heterojunction strategy holds promising potential for visible light-driven photoelectrochemical water splitting.

Noble-metal-free surface-enhanced Raman spectroscopy (SERS) substrates have the advantages, such as abundant resources, uniformity, good biocompatibility, and chemical stability, and they have sparked widespread attention in food safety assessment. However, the lack of controllable synthesis and fabrication method limits their performance in practical applications, especially in the production of high SERS activity substrates. In this study, we introduce a femtosecond laser direct writing technique to precisely manipulate and modify microstructures, successfully fabricating micro-rings of different sizes. Benefiting from the localized field enhancement effect of the optical microcavity, the Sb 2 S 3 micro ring exhibits significantly enhanced Raman signals compared to the unmodified Sb 2 S 3 thin film and the degree of signal enhancement is closely related to the size of the micro rings. Notably, the in-situ formed Sb nanoparticles during the micro ring fabrication process generate pronounced plasmonic effects. These plasmonic hot spots synergistically couple with the localized field enhancement of the optical microcavity, enabling secondary amplification of Raman signals. Furthermore, we used rhodamine 6G (R6G) and basic orange II as probe molecules, and the results indicate that the proposed Sb 2 S 3 micro-ring substrate exhibits excellent SERS performance. This study demonstrates the potential of using advanced laser technology to manufacture highly active noble-metal-free SERS substrates and highlights the importance of microstructure design in enhancing Raman signals, providing new insights for future applications in food safety detection and other fields.

Stibnite (Sb2S3) is a promising material in photoelectronic and energy devices, but it frequently exhibits sheaf-like and hierarchical-like structures that consist of secondary nanorods (NRs) or nanowires (NWs) because of its spatial fractal splitting growth habit. Foreign ions or seeds enable the alteration of the growth dynamics and the consequent shape engineering of nanocrystals. We here report that the introduction of trace amounts of isovalent Bi3+ ions (typically 1–2 atom% Bi/Sb) is efficient to synthesize highly disperse, uniform Sb2S3 NRs with reduced diameters and lengths. Two temperature-dependent growth mechanisms stemming from the presence of Bi ions, the full splitting growth at high temperature and the seeded growth at low temperature, are proposed to demonstrate the formation of separated, thinner NRs. Meanwhile, the surfactant removal and the coupling with p-type CuSCN are simultaneously performed on these Sb2S3 NRs, and the resultant CuSCN/Sb2S3 composite, which contains a large amount of point-to-surface contact p–n heterojunctions with a suitable band alignment, holds promise in self-powered UV-visible photodetectors via the photovoltaic effect.

Antimony sulfide (Sb 2 S 3 ) is a relatively abundant and environmentally friendly emerging photovoltaic material, which has been gradually applied in solar cells and photocatalysis. It has high light absorption capacity, but it suffers many deep-level defects and is prone to recombination of electron-hole pairs within itself. Here, by constructing the Sb 2 S 3 /CdIn 2 S 4 S-scheme heterojunction, we avoided the problem that electrons and holes cannot be separated and transported effectively due to many Sb 2 S 3 defects (more recombination centers), and improved its application in the field of photoelectrochemical water splitting. Meanwhile, in order to further improve the performance of Sb 2 S 3 /CdIn 2 S 4 photoelectrode, we introduced CdS energy platform between Sb 2 S 3 and CdIn 2 S 4 to form a Sb 2 S 3 /CdS/CdIn 2 S 4 cascaded S-scheme heterojunction. Compared with Sb 2 S 3 monomer, Sb 2 S 3 /CdS/CdIn 2 S 4 had higher absorbance intensity, IPCE value, ABPE value, and lower charge transfer resistance. In addition, the photocurrent density of the Sb 2 S 3 /CdS/CdIn 2 S 4 photoelectrode was about 4.20 mA/cm 2 (1.23 V vs. RHE), which was 1.3 times higher than that of the Sb 2 S 3 /CdIn 2 S 4 photoelectrode (3.29 mA/cm 2 ) and 3.2 times higher than that of monomer Sb 2 S 3 photoelectrode (1.32 mA/cm 2 ). This method offers new prospects for optimizing the performance of antimony chalcogenides photoelectrodes for photoelectrochemical water splitting.

Unavoidable impurities form in Sb 2 S 3 absorber fabricated by conventional chemical bath deposition method which is harmful to the photovoltaic performance of Sb 2 S 3 -sensitized solar cells. To obtain high quality Sb 2 S 3 absorber, a two-step template method is introduced to deposit Sb 2 S 3 on mesoporous TiO 2 film. This template method is performed by dipping ZnS-coated TiO 2 films in a Sb source solution for several minutes. This low temperature method with short operation time allows large area deposition of Sb 2 S 3 . Properties of ZnS and Sb 2 S 3 are systematically studied. X-ray photoelectron spectroscopy confirms the absence of impurities. The optimized Sb 2 S 3 device exhibits a power conversion efficiency (PCE) of 3.69%, with an open-circuit voltage of 0.514 V, a short-circuit current-density of 12.14 mA/cm 2 , and a fill factor of 59.1% under AM 1.5G illumination which is better than the device fabricated by chemical bath deposition. The PCE of our Sb 2 S 3 devices showed an obvious increase after 1–2 months storage which may be caused by reconstruction of the ZnS/Sb 2 S 3 coating fabricated by partial cation exchange.

Nanocrystalline Sb 2 S 3 was synthesized using chemical bath deposition, and TiO 2 –Sb 2 S 3 composite electrodes were fabricated by combining the nanocrystalline Sb 2 S 3 with mesoporous TiO 2 thin films. The composite electrodes were characterized by XRD, SEM, TEM, EDX, and UV–Visible absorption. P3HT and CuSCN were used as hole-transporting materials, and thermally evaporated silver films were used as counter electrodes in the fabricated solar cells. The solar cells with P3HT or CuSCN as hole-transporting material exhibit the highest efficiencies of 0.34 and 0.47 %, respectively.

Constructing organic-inorganic semiconductor heterojunctions is an efficient way to inhibit the recombination of photogenerated charge carriers and enhance photocatalytic performance of semiconductor. Herein, a novel heterojunction antimony sulfide-perylene diimides (Sb 2 S 3 -PDI) heterojunction has been fabricated through a facile hydrothermal method. Compared with bare Sb 2 S 3 and PDI, the Sb 2 S 3 -PDI hybrid has showed significantly superior activity in photocatalytic reduction of Cr (VI). The superior photocatalytic performance of Sb 2 S 3 -PDI hybrid is due to the formation of type-I heterojunction, which leads to a more efficient separation and migration of photogenerated electron-hole pairs. This work is expected to promote continued interest in the construction of organic-inorganic semiconductor composites with enhanced photocatalytic performance.

Antimony sulfide (Sb2S3) possesses a high theoretical capacity and excellent reversibility, making it a promising anode material for lithium-ion batteries (LIBs). However, its poor intrinsic conductivity and significant volume changes during charge/discharge cycles severely limit its cycling stability and rate performance. In this study, a novel composite material was synthesized by electrostatically assembling Sb2S3 nanowires (Sb2S3 nw) onto MXene nanosheets as a potential anode material (SbSMX). The introduction of highly conductive MXene substrates enhances electron transfer between the distinct interfaces of Sb2S3 and MXene. Additionally, the constructed 1D–2D structure promotes ion transport within the electrode, while the mechanical flexibility of MXene effectively mitigates the severe volume expansion of Sb2S3. As a result, the SbSMX composite exhibits a high capacity of 813 mA h g–1 at a current of 50 mA g–1, stable cycling performance with a capacity of 735 mA h g–1 after 100 cycles at 100 mA g–1 (88% retention), and excellent rate capability, achieving 466 mA h g–1 at a current of 3 A g–1.

Antimony sulfide (Sb 2 S 3 ) films were successfully prepared by spin coating Sb 2 S 3 micro-/nanorods with different sizes on glass slides, which was synthesized via a facile and rapid microwave irradiation method. The prepared Sb 2 S 3 micro-/nanorods and films were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM) and water contact angle (CA). The as-prepared Sb 2 S 3 films exhibited different surface wettabilities ranging from superhydrophilicity to superhydrophobicity, which was strongly dependent on the diameter of Sb 2 S 3 micro-/nanorod. Sb 2 S 3 film made by nanorods possessed superhydrophobic surface and high water adhesive property. After surface modification with stearic acid, the superhydrophobic surface exhibited an excellent self-cleaning property owing to its low adhesive force. The clarification of three possible states including Wenzel's state, “Gecko” state and Cassie's state for Sb 2 S 3 film surfaces was also proposed to provide a better understanding of interesting surface phenomena on Sb 2 S 3 films.

In this paper, two different nanostructures of CuO seeds layer and CuO nanocones array as photocathode were introduced for TiO2/Sb2S3 heterojunction to study the photoelectrochemical properties. The all-solid FTO/TiO2/Sb2S3/CuO seeds layer/FTO device and FTO/TiO2/Sb2S3/CuO nanocones array/FTO device could realize photoelectric conversion with a small photocurrent and photovoltage, and the photoelectrochemical properties of FTO/TiO2/Sb2S3/CuO nanocones array/FTO is even lower than that of the FTO/TiO2/Sb2S3/CuO seeds layer/FTO device due to the limited contact area between Sb2S3 and CuO nanocones. When the electrolyte I3−/I− was filled into space between Sb2S3 and CuO seeds (nanocones array) photocathode, the photoelectrochemical performance was significantly improved, especially, the photocurrent is enhanced by two (four) orders of magnitude and the photovoltage is enhanced by two orders of magnitude than the device for both photocathodes without electrolyte. For better understanding the photoelectrochemical mechanism of different CuO nanostructure photocathodes, dynamic characterization of intensity-modulated photocurrent/photovoltage spectroscopy and photoelectrochemical impedance spectroscopy were carried out to study photo-generated electron and hole behaviors. Results showed that charge transfer rate in device with CuO seeds layer photocathode is significantly enhanced by CuO nanocones array photocathode. The better hole transfer also improved the charge separation in Sb2S3 and reduced their recombination rate, which results in the enhanced photocurrent and photovoltage by CuO nanocones array photocathode.

The large volume expansion and sluggish dynamic behavior are the key bottleneck to suppress the development of conversion-alloying dual mechanism anode for potassium-ion batteries (PIBs). Herein, Sb 2 S 3 nanorods encapsulated by reduced graphene oxide and nitrogen-doped carbon (Sb 2 S 3 @rGO@NC) are constructed as anodes for PIBs. The synergistic effect of dual physical protection and robust C-Sb chemical bonding boosts superior electrochemical kinetics and great electrode stability. Thus, Sb 2 S 3 @rGO@NC exhibits a high initial charge capacity of 505.6 mAh·g -1 at 50 mA·g -1 and a great cycle stability with the lifetime over 200 cycles at 200 mA·g -1 . Ex situ XRD, XPS, and TEM characterizations confirm that the electrode undergoes a multielectron transfer process (Sb 2 S 3 ↔ Sb + K 2 S ↔ KSb + K 3 Sb), where K-ion insert into/extract from the material via dual mechanisms of conversion and alloying. This work sheds a light on the construction of high-performance anode materials and the understanding of K-ion storage mechanism.
