Bi 2 S 3 with a 2D van der Waals structure has attracted much attention due to its high conductivity, large absorption coefficient, and environmental friendliness. The preparation of tunable optoelectronic devices can be realized by exploiting and tuning Bi 2 S 3 intrinsic defects. In this work, a simple and rapid method for the preparation of bismuth sulfide thin films and successfully prepare Bi 2 S 3 with sulfur vacancies (S vac ) (LA-Bi 2 S 3 ) and oxygen passivated (S vac ) (AP-Bi 2 S 3 ) was presented. The defect state difference of the two devices leads to exhibit different optoelectronic properties. Under 638 nm and 1310 nm illuminations, the LA-Bi 2 S 3 photodetectors exhibit responsivities of up to 2250 and 3.6 mA/W and detectivities of 1.69 × 10 12 and 2.6 × 10 9 cm·Hz 1/2 W −1 , while the AP-Bi 2 S 3 photodetectors have ultra-fast on/off speeds of 1 ms and 8 ms, and on/off ratio up to 3 × 10 3 . The preparation method of the tunable optoelectronic devices gives a new avenue for defect tuning in metal sulfides and for the preparation and application of optoelectronic devices.

Four alkali metal bismuth sulfates, NaBi(SO 4 ) 2 · H 2 O ( 1 ) and ABi(SO 4 ) 2 [A = K ( 2 ), Rb ( 3 ), Cs ( 4 )], were successfully synthesized by hydrothermal methods. The crystal structure of 1 features a three-dimensional tunnel framework constructed by BiO 9 tri-capped trigonal prisms and SO 4 tetrahedra interconnected via common corners and edges. Compound 2 exhibits a two-dimensional 2 ∞ [Bi(SO 4 ) 2 ] – double-layered structure, assembled by one-dimensional 1 ∞ [BiS(1)O 4 ] + chains which are linked via S(2)O 4 2– tetrahedra. The isostructural compounds 3 and 4 possess a two-dimensional layered structure, and the layers being composed by BiO 8 square antiprism and SO 4 tetrahedra. The alkali metal cations are located between the layers or in the tunnels of the structures, respectively. The differences in the crystal structures of the title compounds can mainly be attributed to the different sizes of the alkali metal cations and their different coordination environments. Thermogravimetric analysis evidence that compound 1 losses one equivalent of water at 120 °C whereas the anhydrous compounds 2 – 4 are stable up to about 450, 575, and 578 °C, respectively. The solid-state UV/Vis/NIR diffuse reflectance spectra indicate bandgaps of approximately 4.48, 4.43, 3.98, and 3.96 eV for compounds 1 – 4 , respectively.

Hierarchical Bi 2 S 3 hollow spheres have been synthesized by a facile solvothermal process in the presence of sodium tartrate . The hollow spheres are composed of numerous ultrathin nanorods with the average diameter of 15 nm. Based on the time dependent electron microscope observations, the formation mechanism of such hierarchical structures has been proposed as a sodium tartrate directed self-assembled process and oriented attachement mechanism. The morphology and size of the subunits can be controlled by adjusting the amount of sodium tartrate. The Nitrogen adsorption-desorption measurements suggest that mesopores exist in these hollow spheres. The as-derived Bi 2 S 3 hollow spheres exhibit excellent electrochemical hydrogen storage properties.

In order to develop non-noble metal-based electrocatalysts for glucose oxidation, the Ni-doped, urchin-like Bi 2 S 3 particles were prepared by a solvothermal method using the solvent of ethylene glycol/H 2 O. The obtained products were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy and X-ray diffraction. The background signal from capacitance current is relatively low and the electrocatalytic oxidation current of glucose relatively high due to the urchin-like nanostructure of Bi 2 S 3 particles and high surface area where the presence of Bi also improves the electrocatalytic performance of Ni I I /Ni I I I shift.

Effects of different specials carbon materials on the performance of negative plates were studied. The addition of carbon materials P1 and P2 greatly improved the high-rate partial-state-of-charge (HRPSoC) cycle performance of the batteries. A negative plate completed 18489 HRPSoC micro-cycles in the first cycle-set when the concentration of P2 was 0.9%. Special properties are required for the carbon materials to be used as additives to the negative electrode materials. Firstly, the carbon material added to the negative electrode should have a good binding force with lead and lead sulfate. Secondly, the carbon material should have a large specific surface area and a larger pore volume. Addition of bismuth sulfide can inhibit the hydrogen evolution of the lead-carbon negative plates. Negative electrodes modified with a C/Bi 2 S 3 composite exhibited good low temperature performance.

There are strong radiological hazards and the risk of direct cell damage in living organisms for radioactive iodate (131IO3–/129IO3–). Thus, it is essential to capture and remove them. In the contribution, the micro flower-like Bi2S3 (MF-Bi2S3) was prepared via a hydrothermal method to investigate its adsorption behavior toward IO3–. MF-Bi2S3 exhibits the maximum adsorption capacity of 875.6 mg/g for IO3– at pH ≈ 3, and the adsorbent achieves a removal efficiency of 98.98% within 2 h. Furthermore, the removal efficiency of MF-Bi2S3 can still reach 96.37% at high concentrations of coexisting anions such as Cl–, SO42–, NO3–, and CO32–, demonstrating excellent anti-interference performance. In simulated artificial groundwater, the adsorbent achieves a removal rate of 88.8% for IO3–, suggesting its potential to solve the problem of IO3– in actual wastewater. Notably, the adsorbed products change depending on iodine content, with BiI3O9 and BiOI as the intermediate products, and the final product is BiOIO3. X-ray photoelectron spectroscopy detects the presence of I2 and I3– in the product, which is attributed to the reduction and fixed to iodine by S2–. Meanwhile, the corresponding S2– becomes SO42– and remains in the liquid after the reaction. This work provides a breakthrough solution for effectively removing IO3–.

As a photoelectric material, bismuth sulfide (Bi2S3) can convert light signals into electrical signals and thus hold tremendous promise in constructing wireless electrical stimulation to accelerate nerve regeneration. However, the easy recombination of electrons and holes weakens the electrical stimulation effect. Herein, core–shell Bi2S3@PPy nanorods were prepared via the in situ hydrothermal polymerization of conductive polypyrrole (PPy) on Bi2S3 and were then blended into poly-L-lactic acid powder to fabricate a nerve conduit via laser additive manufacturing. Under a rotating magnetic field, conductive Bi2S3@PPy in the conduit could cut the magnetic inductance line to generate induced electromotive force that could drive the electrons and holes of Bi2S3 in opposite directions, thereby achieving efficient separation. Results indicate that the enhanced electron–hole separation boosted photocurrent generation, with an output current of 7.5 μA, which was significantly higher than the photocurrent under light irradiation (5.0 μA) and the induced current under magnetic field (2.5 μA). Immunofluorescent staining demonstrated that the enhanced photocurrent could up-regulate the expression of neuronal markers Nestin and GFAP. Moreover, the intracellular influx of Ca2+ was improved, which indicated that the differentiation of BMSCs into neurons was promoted. Overall, this work provides a potential wireless electrical stimulation strategy for accelerating nerve repair.

Ternary sulfides have been widely studied for photocatalytic applications recently due to their flexible chemical composition and feasible band structure regulation. Theoretical research indicates huge potential of AgBiS2 in photocatalysis despite the lack of experimental data. Herein, single crystalline AgBiS2 hollow octahedrons were developed for CO2 photoreduction with amorphous ZIF-67 frameworks as outer layers. The predominant exposure of (111) planes and central cavities endowed AgBiS2 hollow octahedrons with sufficient light harvesting and electron transfer capability. The core–shell AgBiS2@ZIF-67 heterostructure significantly facilitated the separation of photogenerated carriers on the interface and electron accumulation around the active sites, further inducing stronger electrostatic attraction between ZIF-67 and ruthenium bipyridine complexes as photosensitizers. In consequence, AgBiS2@ZIF-67 heterostructures with medium thickness of outer layers exhibited the optimum photocatalytic efficiency towards CO2 photoreduction with the average CO and H2 production rates of 2.27 mmol gcat−1 h−1 and 0.78 mmol gcat−1 h−1, which qualified AgBiS2 hollow octahedrons as a universal platform for cocatalyst loading in heterogeneous catalysis.

We developed a facile in-situ growth method to construct amorphous-based Bi 2 S 3 /Bi 2 WO 6 heterostructures at room temperature. As demonstrated by HRTEM , XPS and EDX-mapping, amorphous state Bi 2 S 3 dispersed uniformly on the surface of crystalline Bi 2 WO 6 hollow spheres. The photocatalytic activities of prepared Bi 2 S 3 /Bi 2 WO 6 heterostructures were evaluated by the photodegradation of RhB and TC under visible light irradiation, indicating that the introduction of appropriate amorphous Bi 2 S 3 significantly improved the photocatalytic activity of Bi 2 WO 6 . The amorphous/crystalline contact in Bi 2 S 3 /Bi 2 WO 6 heterostructures played a crucial role in the enhancement of photocatalytic efficiency. Based on DRS, photoluminescence spectra, photocurrent intensity, electrochemical impedance spectroscopy and OCVD measurements, it was proposed that the enhanced performance could be ascribed to increased visible light utilization, promoted separation efficiency and prolonged life time of photogenerated electron-hole pairs by the introduction of amorphous Bi 2 S 3 . This work may provide new insights into the construction of amorphous-based composited heterostructures for improving photocatalytic activity.

Hazardous hexavalent chromium removal from wastewater is an urgent issue in industry environmental pollution. In this work, hollow Bi 2 S 3 nanospheres have been successfully synthesized from unique Bi 2 O 3 porous nanospheres via Kirkendall effect through hydrothermal process. It was found that the sulfur source and the initial Bi 2 O 3 templates played key roles in the formation of the uniform morphologies and structures through an anion exchange process. Compared with other Bi 2 S 3 samples, the synthesized hollow Bi 2 S 3 nanospheres exhibited much enhanced photocatalytic ability for Cr(VI) photoreduction. XPS analysis demonstrated that Cr(VI) was reduced to less harmful Cr(III) species over hollow Bi 2 S 3 nanospheres under visible-light irradiation. More importantly, the hollow Bi 2 S 3 nanospheres remained high efficiency and good stability in the recycling Cr(VI) photoreduction, and exhibited remarkable Cr(VI) removal ability in actual electroplating industry wastewater treatment.

Rational design of electrode materials with an excellent structure and morphology is crucial for improving electrochemical properties. Herein, various unique nanostructured Bi2S3 materials with controllable morphology were obtained through a simple and efficient oil bath reaction strategy. Bi2S3 with different morphologies can be obtained by regulating the polarity of solvent, and the lattice spacing can also be adjusted. The Bi2S3 nanomaterials obtained with ethanol as solvent (BS-3) show a three-dimensional nanoflower-like structure assembled with porous layers. The unique structure facilitates the transport of ions and accommodates the volume variation of Bi2S3 during energy storage. Consequently, BS-3 nanoflowers exhibited superior cycling stability and excellent high-rate capability for lithium storage (maintained a high capacity of 923.8 mA h g–1 after 950 cycles at 1.0 A g–1) and excellent sodium storage. We provide guidance for precise synthesis and energy storage application of Bi2S3 nanomaterials.

High theoretical capacity of Bi2S3 propels it toward an ideal anode material for lithium-ion batteries (LIBs); however, rapid capacity attenuation and poor long-term stability are major barriers to widespread application. In this work, an oxygen self-doping strategy was utilized to synthesize O–Bi2S3@C, significantly increasing the amount of active sites for lithium-ion storage. Meanwhile, sulfur vacancies were formed to improve the electrical conductivity and ionic transport efficiency, enhance the long-term stability, and accelerate the electrochemical kinetics of Bi2S3@C. O-BSC-S1:3 anode exhibits a reversible capacity of 673.1 mAh g–1 at 0.2 A g–1. It retains a long-term capacity of 596.3 mAh g–1 over 1100 cycles at a high density of 3 A g–1 in LIBs. Moreover, the installed O–Bi2S3@C//LiCoO2 full battery offers exceptional reversible capacity and remarkable cyclability (325.2 mAh g–1 after 200 cycles) at 0.2 A g–1. The combined strategy of oxygen self-doping and sulfur vacancy effectively enhances the reversible capacity and cycling life of Bi2S3, providing an approach for the design of high-performance transition metal sulfide anodes for LIBs.
