In this work, a dual-functional electrochemical sensor has been proposed based on Sn-doped defective Bi 2 S 3 (TDDB) microspheres, which exhibited the excellent electrochemical performance on Pb(II) and H 2 O 2 detection. The TDDB offered a satisfied detection limit of 8.0 nM towards Pb(II) with a sensitivity of 96.7 μA ⋅ μM −1 . As a H 2 O 2 sensor, a high sensitivity of 3540 μA mM −1 cm −2 was obtained in a linear range from 0.45 mM to 10 mM with a detection limit of 10 nM. Moreover, the electrochemical detection of Pb(II) in Taihu Lake and H 2 O 2 in human serum was achieved with high reliability and good recovery.

Single crystalline flower-like Bi 2 S 3 nanostructures were successfully synthesized via a simple, facile and green hydrothermal method, with the assistance of D -penicillamine. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), and found their morphologies mainly depend on the ratios of Bi 3 + to D -penicillamine, as well as the reaction temperature and time. And the possible growth mechanism has been discussed in some detail. In addition, the as-prepared Bi 2 S 3 nanoflowers show good hydrogen storage ability. This strategy can be potentially expanded to prepare other metal chalcogenides materials.

Owing to the high X-ray absorption, Bi 2 S 3 nanocrystals are widely used as CT contrast agents. Here, we prepared uniform Bi 2 S 3 nanorods via a hot injection method using bismuth (III) chloride, sulfur and oleyl amine. The resulting nanocrystals were coated with tetraethylorthosilicate (TEOS) and 2-[methoxy(polyethyleneoxy)propyl]yrimethoxysilane (PEG-silane) for the biological utility. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results showed that the Bi 2 S 3 nanorods had an orthorhombic structure with the length of 14 nm and the diameter of 7 nm, respectively. Composite nanoparticles (0.0226 M) gave a CT number at 550 (HU), which was higher than that of the commercial available iobitridol CT contrast agent. Furthermore, cell experiments revealed that Bi 2 S 3 composite nanoparticles had a low cytotoxicity with a concentration up to 0.01 M of Bi for 24 h.

Here, the lamellar-shaped Bi 2 S 3 grown on a porous TiO 2 monolith was obtained by a two-step method including a sol–gel route and hydrothermal treatment. The photocatalytic activity of the as-synthesized Bi 2 S 3 /TiO 2 composites was evaluated for photodegradation of methylene blue (MB) dye in aqueous solution under the visible-light irradiation. Based on our experimental results, 5% (molar ratio of Bi 2 S 3 to TiO 2 ) Bi 2 S 3 /TiO 2 photocatalysts exhibited a maximum photodegradation rate of MB up to 96.9% under visible-light irradiation for 120 min. Our findings indicated that the lamellar-shaped Bi 2 S 3 can extend the light absorption up to visible areas, and porous TiO 2 can provide enhanced specific surface area and more mass transfer pathway to enhance the photodegradation efficiency. Furthermore, porous TiO 2 can accept the electrons from the Bi 2 S 3 conduction band due to the relatively positive electrode potential to impede the photoproduced electron and hole combination to result in advanced photocatalytic performance.

Bi 2 S 3 -based thermoelectric materials without toxic and expensive elements have a high Seebeck coefficient and intrinsic low thermal conductivity. However, Bi 2 S 3 suffers from low electrical conductivity, which makes it a less-than-perfect thermoelectric material. In this work, halogen elements F, Cl, and Br from halogen acid are successfully introduced into the Bi 2 S 3 lattice using a hydrothermal procedure to efficiently improve the carrier concentration. Compared with the pure sample, the electron concentration of the Bi 2 S 3 sample treated with HCl is increased by two orders of magnitude. An optimal power factor of 470 µW m −1 K −2 for the Bi 2 S 2.96 Cl 0.04 sample at 673 K is obtained. Density functional theory calculations reveal that an effective delocalized electron conductive network forms after Cl doping, which raises the Fermi level into the conduction bands, thus generating more free electrons and improving the conductivity of the Bi 2 S 3 -based materials. Ultimately, an excellent ZT of ≈0.8 is achieved at 673 K for the Bi 2 S 2.96 Cl 0.04 sample, which is one of the highest values reported for a state-of-the-art Bi 2 S 3 system. The energy conversion efficiency of the module reaches 2.3% at 673 K with a temperature difference of 373 K. This study offers a new method for enhancing the thermoelectric properties of Bi 2 S 3 by adding halogen acid in the hydrothermal process for powder synthesis.

The excessive use of antibiotics and subsequent release into the aquatic environment causes deleterious effects on organisms. Using easily separable catalysts to remove antibiotics from aquatic environments is an effective strategy to release the burden of the aquatic ecosystem. Herein, as the natural porous cellulose fiber, Juncus effusus (JE) exhibits distinctive designability on the functional materials. The JE-based W-doped Bi 2 S 3 photocatalysts (W-Bi 2 S 3 -JE) were obtained by in-situ coating on the surface of JE fibers to improve the photodegradation performance of tetracycline (TC) antibiotic pollutants. Owing to the natural porous net-working structure of JE fiber, the aggregation of particles is reduced, promoting adsorption and photocatalysis. Under the condition of pH = 3.0 and mass of photocatalyst is 100 mg, the photodegradation efficiency is 98 % under irradiation for 180 min and the photodegradation efficiency could maintain 78 % after five cycles. Finally, the cultivation of crops was conducted to investigate the purification property of the solution after photocatalytic degradation. Compared with the solution before photodegradation, mung bean seeds can take root and germinate well irrigated by the solution after photodegradation and the growth is as strong as that of agricultural irrigation water. The W-Bi 2 S 3 -JE photocatalyst provides an attractive approach to restore the aquatic ecosystem polluted by antibiotics of TC, improving the application potential in environmental remediation.

Photocatalytic removal of antibiotic such as ciprofloxacin from polluted water is of great value for eco-environment protection. To further enhance the piezoelectric effect in photocatalysis, we designed and synthesized a ternary heterojunction piezoelectric photocatalyst through uniformly loading MoS 2 nanosheets onto BiFeO 3 (BFO) nanofibers, namely MoS 2 /Bi 2 S 3 /BFO. Piezoresponse force microscopy and Kelvin probe force microscopy demonstrated its enhanced piezoelectric properties, showing a maximum amplitude displacement of 395.51 pm under a voltage of 9.91 V and a surface potential difference of 66.50 mV. Finite element simulations indicated that the ternary heterojunction could achieve a larger piezoelectric potential. Piezoelectric photocatalytic degradation experiments revealed that MoS 2 /Bi 2 S 3 /BFO achieved a ciprofloxacin degradation efficiency of 96.6 % within 75 min, significantly higher than that of pure piezoelectric catalysis (25.5 %) and photocatalysis (60.5 %). Analysis of intermediate products and detection of active species ( OH and O 2 − ) during degradation suggested an S-Scheme migration pathway of photogenerated charge carriers, enhancing the piezoelectric photocatalytic performance of the material. This study provides an efficient ternary heterojunction composite piezoelectric photocatalyst for the antibiotic degradation and energy conversion, thus offers a new approach for developing novel BFO-based composite piezoelectric photocatalysts.

The development of textile-based wearable devices has been a hot research topic in recent years. However, a fabric-supported optical switch has never been reported. Herein, a pair of interdigital silver electrodes and hydrothermally synthesized Bi2S3 nanowires (NWs) were screen-printed successively onto silk fabric to construct a silk fabric-based flexible optical switch. The device showed irradiation power-dependent light-on currents and was able to respond to blue, green and red light. A fast response/recovery time of less than 2 ms could be achieved. After 120 cycles of distortion or bending, the light-on current remained as high as >85%. Bi2S3 NW films with different patterns could be printed on top of the devices without significantly affecting their performance. It was also demonstrated that the system could be utilized to trigger the rotation of an electrical fan. This work may provide a facile approach for the preparation of a silk fabric-based optical switch for wearable electronics.

The Type II heterojunction, characterized by its favorable band alignment, facilitated efficient charge separation in photocatalysts. Concurrently, oxygen vacancies can enhance light absorption and activated reactants, thereby improving photocatalytic efficiency. This study presented the synthesis of Bi-TCPP/Bi 2 S 3 heterojunction photocatalysts, which were rich in oxygen vacancies, using a green, one-pot method. The composite exhibited superior photoelectrochemical and photocatalytic reduction properties, achieving a rate constant of 0.03829 min −1 for Cr(VI) reduction and a remarkable reduction rate of 95.73%. After five cycles, the photocatalytic activity remained above 91.30%, demonstrating excellent stability and efficiency in reducing persistent pollutants. This work introduced a novel strategy for photocatalyst design and made a significant contribution to the fields of environmental remediation and green chemistry.

A type I core/shell structured Bi2S3@ZnS photocatalyst was synthesized by an electrostatic interaction mechanism and used for the photoelectrochemical detection of Cu2+. The Bi2S3@ZnS composite showed excellent photoelectrochemical activity and stability due to the high photoelectrochemical activity of Bi2S3 and the anti-photocorrosion function of the ZnS shell. In addition, the ZnS shell also provided a transfer platform for the photogenerated holes through its acceptor states (i.e. VZn and IS) and suppressed the recombination of photogenerated carriers. The photocurrent signal of the obtained Bi2S3@ZnS/ITO electrode was much higher than that of pure Bi2S3 under visible-light irradiation. When it was used for the photoelectrochemical sensing of Cu2+, a wide detection range (0.003–30.0 μM) and a low detection limit (0.001 μM) were observed. The sensor also displayed high stability and acceptable selectivity. It was applied to detect real samples and good results were achieved.

The direct growth of semiconductor nanowire (NW) arrays horizontally aligned on a substrate is critically important for the applications of NWs in electronic or optoelectronic devices at the circuit level. The strict requirement of lattice matching between a substrate and a material in the covalent epitaxy of crystals makes the wire arrays be grown on the substrates only with similar lattice parameters. Herein, a van der Waals epitaxy route is developed to realize the in-plane growth of large-scale Bi 2 S 3 NW arrays on mica with a large lattice mismatch. The orthorhombic Bi 2 S 3 NWs grow epitaxially with the axial direction of ⟨ 001 ⟩ Bi 2 S 3 along the six symmetric directions of the mica. Transmission electron microscope measurements show that the epitaxial relationships are [ 001 ] Bi 2 S 3 | | [ 100 ] mica and [ 3 2 ¯ 0 ] Bi 2 S 3 | | [ 010 ] mica along the length and width directions of the wires, respectively. More importantly, photodetectors based on Bi 2 S 3 NWs show a wide photoresponse spectrum range from 500 to 980 nm. A high responsivity (5233 A W −1 ) and a specific detectivity (1.8 × 10 12 Jones) are achieved under 830 nm light irradiation with ultralow intensity (64 nW cm −2 ). In addition, the photodetectors exhibit high stability with at least 48 day storage in ambient atmosphere or with 1000 times bending.

Bi 2 S 3 /Ti 3 C 2 T x nanomaterials were successfully prepared through a simple hydrothermal method. Various methods were used for their characterization, including XRD, XPS, SEM, EDS, and BET, along with testing their gas-sensing properties. The results showed that the response value to 100 ppm ammonia at room temperature reached 107%, which was 14.1 times higher than that of pure few-layer MXene. After undergoing anti-humidity interference testing, we observed that Bi 2 S 3 /Ti 3 C 2 T x exhibited a higher response value in real-time monitoring of ammonia as humidity increased. Specifically, under 90% humidity conditions, its response value reached 1.32 times that of normal humidity conditions. This exceptional moisture resistance ensures that the sensor can maintain stability, and even exhibit superior performance, in harsh environments. Therefore, it possesses excellent selectivity, high-moisture-resistance, and long-term stability, making it significant in the field of medical and health monitoring. Graphical abstract
