An alkali-treated MXene-SnS hybrid was prepared through hydrothermal methods. The Alk-MXene microplates provide highway for electronic transport, and the 3D wrinkled morphology ensures sufficient channels for Li + diffusion. The alkali treatment of MXene gives Alk-MXene@SnS enhanced binding strength, which allows the SnS nanosheets to remain firm binding with the Alk-MXene substrate during cycling and overcome capacity decay caused by large volume change. The synergy between the two components guarantees the hybrid excellent electrochemical properties by enabling high electronic/ionic conductivity and superior kinetic properties as evidenced by EIS, GITT tests and DFT calculation. As a result, the Alk-MXene@SnS retains specific capacities of 519 mAh/g after 100 cycles at 200 mA g −1 , and 330 mAh/g at the high rate of 8000 mA g −1 . In addition, a reversible capacity of 421 mAh/g can be provided after long term cycle test at 1000 mA g −1 for 800 cycles.

Potassium-ion batteries (PIBs) have appealed increasing attention due to the inexpensive K-element resources and satisfactory electrochemical properties. Presently, there are still challenges for developing desirable anode materials. Two-dimensional metal sulfides exhibit high specific capacity as host for PIBs, yet the dissolution and agglomeration of unstable reaction intermediate K x S y (K 2 S, K 2 S 5 ) inescapability induces large loss of active ingredients and poor reactions reversibility, leading to inferior lifespan. Herein, polar polysulfide VS 4 is introduced into SnS nanosheets with constructing layered VS 4 /SnS heterostructure anchored in graphene scaffold (VS 4 /SnS@C). In this framework, VS 4 with unsaturated bridging (S 2 ) 2– can act as the anchoring sites to stabilize intermediates K x S y with efficient entrapment effects. Moreover, the heterostructure can maintain layered SnS and regulate the distribution of K x S y with high conversion reversibility. The reaction reversibility and intermediate absorptivity are enhanced, as confirmed by in situ X-ray diffraction analysis and theoretical calculations. Consequently, the VS 4 /SnS@C electrode exhibits ultra-long lifespans, which achieves a capacity of 168.4 mAh g –1 at 1 A g –1 after 6000 cycles. This strategy of heterostructure design facilitates the understanding of K-storage mechanisms and significantly enhances the reaction reversibility, providing a thought to address the challenges in metal sulfide anodes toward the development of high-performance PIBs.

As an emerging environmental purification material, piezoelectric photocatalysts can significantly enhance catalytic performance through the coupling of mechanical stress and light energy. In this study, ZnO nanorods were grown on the surface of SnS microdisks to successfully construct ZnO/SnS heterojunction composite materials. This material exhibited excellent piezoelectric photocatalytic degradation activity toward tetracycline hydrochloride under simulated sunlight irradiation. The reaction rate constant of the optimal sample ZS-0.05 was 4.68 times and 16.4 times that of pure ZnO and pure SnS, respectively. In the experiment of simultaneous application of light and ultrasonic vibration, the piezoelectric photocatalytic efficiency of ZS-0.05 was significantly higher than that of the single photocatalytic or piezoelectric catalytic process, with a synergy factor of 1.36, demonstrating a significant synergistic enhancement effect. This performance improvement mainly originated from the synergistic effect between the built-in electric field at the heterojunction interface and the piezoelectric field generated by the piezoelectric material under stress, which jointly promoted the efficient separation and migration of photogenerated electron–hole pairs. This study provides an idea for the development of efficient piezoelectric photocatalysts and can be used for the solar-mechanical energy-driven degradation of organic pollutants in water.

The energy level alignment (ELA) between electron transport layers (ETLs) and perovskite layers would affect the photovoltaic performance of perovskite solar cells (PSCs), especially for the open-circuit voltage (Voc). However, systematic investigations were rarely reported. In this letter, a series of SnS2/SnS composite ETLs were in situ synthesized, where the doping of SnS was used to adjust the energy level of SnS2 nanosheets. Results showed that electrons could be transferred from perovskite layers to ETLs; even the conduction band (CB) of ETLs was a little higher than that of perovskite layers. In comparison with PSCs based on SnS2 ETLs, the power conversion efficiency (PCE) of PSCs based on SnS2/SnS was enhanced by 27.95% (from 14.13% to 18.08%) with a higher Voc promotion (from 0.94 to 1.08 V). A corresponding explanation and working principle have been proposed. In addition, a stability test demonstrated that PSCs based on SnS2/SnS ETLs possessed much better stability than that of traditional PSCs based on TiO2 ETLs because of the strong interaction of Pb and S. This work proposes a promising future for reducing the Voc loss and improving the stability of perovskites.

As a kind of two-dimensional (2D) materials, tin sulfides including tin(IV) sulfide (SnS2) and tin(II) sulfide (SnS) have been attracting wide attention because of its earth abundance, low cost, and environment-friendly characteristics as promising photovoltaic and photocatalytic materials. Among them, only SnS is a p-type semiconductor with appealing physical properties. However, its further investigation and functionalization have been hampered by the absence of highly crystallized nanostructures relative to other intensively studied tin sulfides, such as tin(IV) sulfide (SnS2). Herein, high quality 2D SnS is synthesized via the chemical vapor deposition (CVD) method, with a new precursor of stannous oxide (SnO). Its morphology and properties are characterized by optical microscopy (OM), scanning electron microscopy (SEM), atomic force microscopy (AFM), energy dispersive spectrometry (EDS), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). Furthermore, field-effect transistors (FETs) and photodetectors based on such SnS are fabricated using Photolithographic-Pattern-Transfer (PPT) technology. The results show that the as-grown SnS is indeed a p-type semiconductor and exhibits high responsivity (156.0 A W−1), normalized detectivity (2.94 × 1010 jones) and external quantum efficiency (4.77 × 104%) with fast response time (5.1 ms) under illumination of a 405 nm laser. This work demonstrates that 2D SnS holds great promise for next-generation optoelectronic applications.

SnS is a low‐cost and environmentally benign semiconductor for photocatalysis and piezocatalysis, but its direct use for peroxymonosulfate (PMS) activation remains limited. Here, we develop a facile Fe substitution strategy to construct atomically dispersed Fe‒S in SnS nanostructures (Fe‐SnS) for efficient PMS activation. The catalytic activity shows a volcano‐shaped dependence on Fe incorporation, with 5% Fe‐SnS (Fe/Sn molar ratio of 4.63%) giving the optimal performance, achieving efficient acetaminophen (APAP) removal with a rate constant of 1.23 min ‒1 , which is 3.84 and 176‐fold higher than those of SnS and commercial SnS, respectively. In situ X‐ray absorption spectroscopy reveals a site‐dependent activation mechanism in which Sn sites directly coordinate with O in PMS. Density functional theory calculations further show that Fe incorporation induces local electronic redistribution around neighboring Sn sites and enhances the Sn–PMS interfacial interaction. Fe incorporation also attenuates the negative surface charge of SnS, further facilitating PMS interaction. Mechanism studies revealed that APAP degradation proceeds via sulfate and hydroxyl radical‐dominated pathway. These findings clarify the distinct roles of host Sn and atomically dispersed Fe sites in PMS activation. Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–O PMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO 4 •− /•OH for APAP degradation, thereby clarifying the distinct roles of host Sn and atomic Fe sites.

Semiconducting metal sulfides have raised strong research interest among researchers as a promising candidate for light-assisted electrochemical water splitting, because they have wide band gap. In order to harvest more light wavelengths for improvement of light-assisted electrochemical
water splitting capacity, we fabricated SnS2/SnS heterojunction nanosheets via facile and environmental route. The SnS2/SnS heterojunction nanosheets were used as photo-electrocatalytic material which exhibited low over potential of −0.64 V at the current density
of 10 mA·cm−2 in 0.5 M NaSO4 solution. Moreover, the SnS and SnS2 nanosheets displayed high over potential values of −0.80 and −0.88 V at the current density of 10 mA·cm−2, respectively. This research finding
may therefore show the potential for use of SnS2/SnS heterojunction nanosheets as low cost and environmentally friendly photo-electrocatalysis.

Tin sulfide (SnS) exhibits the potential to be used as a superior-performance electrode material for potassium ion batteries. However, serious volume expansion and poor ion transport capacity hinder the applications of SnS. In order to solve the above problems, this work designed a structure that parallel WS 2 sheets were embedded in SnS sheets (SnS/WS 2 @C). SnS/WS 2 @C displayed excellent kinetic properties and stability when applied to anode materials for potassium ion batteries, as well as a high reversible capacity. SnS/WS 2 @C maintains a superior specific capacity of 619 mAh g −1 after 100 cycles at 0.2 A g −1 and 210 mAh g −1 at 10 A g −1 . Such excellent performance is attributed to the fact that parallelly oriented WS 2 sheets provide fast channels for the transportation of potassium ions, which significantly improves the kinetic performance of the electrode, and can play an anchoring role for products in the process of charging and discharging by virtue of its excellent stability to effectively prevent structural fragmentation. This work provides new ideas for improving ion diffusion and enhancing the structural stability of transition metal layered compounds while maintaining the capacity advantage.

Space exploration urgently demands novel irradiation-tolerant materials to build the arsenal for outer space use, among which nonlinear optical materials and devices are ever-increasing attractive. Tin sulfide (SnS), a novel two dimensional (2D) BP-analog with enhanced stability under ambient conditions, has exhibited excellent optoelectronic properties on the ground, but its potential as a candidate for space optics remains to be explored. Herein, the spatial adaptability of SnS was evaluated in the simulated space radiation environment. When exposed to 60Co γ-rays at a dose equal to over 45 year accumulation in a typical earth orbit, SnS still maintained its strong third-order nonlinear saturable absorption ranging from visible to near-infrared spectra. Ultrafast spectroscopy is used to study the radiation effects and relevant damage mechanisms that are difficult to be revealed via conventional techniques. This work not only sheds light on the irradiation-induced ionization damage and defects in SnS from the unique perspective of ultrafast excited state dynamics but also provides general guidance for rational design and screening space radiation-tolerant nonlinear optical materials.

Stannous sulfide (SnS) with a unique two-dimensional layered structure is a potential anode material for advanced lithium-ion batteries due to its large interlayer spacing (4.04 Å) and high theoretical specific capacity (1138 mA h g−1). However, large volume expansion and low conductivity lead to poor cycle performance of SnS. In this work, MoS2 modified SnS@ hollow multichannel carbon fibers (MoS2/SnS@HMCFs) were prepared by an electrospinning technique and a hydrothermal method. The resulting material has a unique hollow structure with a heterojunction formed between SnS and MoS2. It not only mitigates the volume change of SnS in the lithiation/delithiation process but also improves the interfacial transport of Li+ and enhances the structural stability of the electrode materials. MoS2/SnS@HMCFs can maintain a reversible specific capacity of 610.1 mA h g−1 (at 0.5 A g−1) after 500 cycles. On this basis, B and P elements were doped into MoS2/SnS@HMCFs to generate lattice defects and accelerate electron transport and further ameliorate the electrical conductivity (from 5.34 S cm−1 to 9.58 S cm−1). In light of the above advantages, the reversible specific capacity of MoS2/SnS@BP-HMCFs is increased to 854.4 mA h g−1 (0.5 A g−1) after 500 cycles compared with MoS2/SnS@HMCFs. Therefore, an anode with a unique hollow structure, heterogeneous structural framework, and doped heteroatoms was constructed, providing a method for the preparation of anode materials tailored for high-performance lithium-ion batteries.

Low-cost quantum-dot sensitized solar cells (QDSSCs) were fabricated by using the earth-abundant element SnS quantum dot, novel TiC counter electrodes, and the organic disulfide/thiolate (T 2 /T − ) redox couple, and reached an efficiency of 1.03 %. QDSSCs based on I − /I 3 − , T 2 /T − , and S 2− /S x 2− redox couples were assembled to study the role of the redox couples in the regeneration of sensitizers. Charge-extraction results reveal the reasons for the difference in J SC in three QDSSCs based on I − /I 3 − , T 2 /T − , and S 2− /S x 2− redox couples. The catalytic selectivity of TiC and Pt towards T 2 /T − and I − /I 3 − redox couples was investigated using Tafel polarization and electrochemical impedance analysis. These results indicated that Pt and TiC show a similar catalytic selectivity for I − /I 3 − . However, TiC possesses better catalytic activity for T 2 /T − than for I − /I 3 − . These results indicate the great potential of transition metal carbide materials and organic redox couples used in QDSSCs. Graphical Solar cells : Quantum-dot sensitized solar cells (QDSSCs) were fabricated using counter electrodes based on earth-abundant SnS and TiC and the organic disulfide/thiolate (T 2 /T − ) redox couple (see figure). The loss of photocurrent in QDSSCs based on different redox couples (I − /I 3 − , T 2 /T − , and S 2− /S x 2− ) was ascribed to the inability of the redox couples to regenerate the sensitizer.
