Since exogenous plant hormones are often employed in agriculture, it is necessary to build a sensitive electrochemical sensor to monitor their residues. This paper describes a flower-like tin disulfide (SnS 2 ) flakes using a hydrothermal method, was loaded onto a carbonized eggshell membrane (CESM). The SnS 2 /CESM composite was subsequently drop-coated onto a glassy carbon electrode (GCE), resulting in the successful construction of an electrochemical sensor (SnS 2 /CESM/GCE) for the detection of maleic hydrazide (MH). The designed sensor demonstrates a wide linear range of 0.1 ∼ 25 µM and 25200 µM, and a low detection limit of 0.0386 µM. Mechanistic studies indicates the electrochemical reaction of MH on SnS 2 /CESM/GCE is controlled by adsorption, which two protons and two electrons are participated in the electrochemical oxidation process. The proposed sensor demonstrated good repeatability and reproducibility, with relative standard deviations (RSDs) of 3.83 % and 2.39 %, respectively. Common interferences had no effect on the detection of MH, with an RSD of 3.16 %. The spiking recovery approach yielded recoveries of MH in tobacco ranging from 94.60 % to 107.60 %. This suggests that the SnS 2 /CESM/GCE sensor has a promising future in agriculture for the quick detection of exogenous phytohormones.

The insertion of a graphene interlayer between van der Waals (vdW) materials could suppress the interlayer recombination to improve interface quality and facilitate charge transport. However, its effect on photovoltaic-mode detectors has rarely been explored. Here, self-powered photodetectors based on WSe 2 /graphene/SnS 2 vdW heterojunctions were assembled and the impact of adding graphene interlayer on its performance was investigated. The p-g-n heterostructure exhibits a photovoltaic characteristic, V OC = 0.13 V and I SC = 0.12 nA under illumination of 2.98 mW/cm 2 @405 nm, lower than that of a control (WSe 2 /SnS 2 ) counterpart ( V OC = 0.19 V and I SC = 1.15 nA). Yet an FF value up to 48.16 % was obtained under an irradiation power density of 0.332 mW/cm 2 @405 nm, which is visibly higher than that of bare WSe 2 /SnS 2 vdW heterostructure . The insertion of graphene interlayer is deemed to reduce the charge traps between vdW materials that are caused by the large concentration difference of majority carriers. However, in case of vdW heterostructure, the subsequently increased leakage current makes the junction less ideal. Thereby interface engineering methods should be used with caution to tune vdW heterostructures on the nanoscale .

Graphical Inner space limited : A micro/nanostructured Si@SnS 2 -rGO (reduced graphene oxide) composite was prepared and used as anodes in lithium-ion batteries. The space-constraining effects of rGO and layered structure of SnS 2 reduced the transmission distance and diffusion barrier of Li + ions and prevented the active particles from accumulating during the electrochemical cycling and alleviated the volume expansion of the material, ensuring excellent electrochemical stability. One of the key challenges for the development of lithium-ion batteries is the preparation of high-performance anode materials. In this paper, a micro/nanostructured Si@SnS 2 -rGO composite is reported in which Si nanoparticles with a particle size of 30 nm are electrostatically anchored on a 3D reduced graphene oxide (rGO) network and mixed with SnS 2 . The step-wise lithiation/delithiation of SnS 2 provided space-constraining effects to accommodate volume expansion and particle aggregation, thereby alleviating the volume expansion of Si during cycling as well as enhancing the structural stability, whereas the rGO in the 3D network stabilized the composite. The composite had a high specific capacity of 1480.1 mAh g −1 after 200 cycles at a current density of 200 mA g −1 and a high stability at rates of 200–3000 mA g −1 . The capacity attenuation after cycling was only 89.18 %. A stable specific capacity (425.5 mAh g −1 ) was achieved after 600 cycles at a current density of 3000 mA g −1 . Therefore, the micro/nanostructured Si@SnS 2 -rGO composite is a promising anode material for use in lithium-ion batteries.

Tin (Sn), owing to its unique electronic structure and inherent suppression of the hydrogen evolution reaction (HER), has garnered significant attention as an electrocatalyst for nitrogen reduction reactions (NRR). Synthesizing high-performance Sn-based heterostructure catalysts, however, remains a substantial challenge. In this study, we employ a combination of interface engineering and doping strategies to introduce iron (Fe) into the SnS 2 /SnO 2 heterostructure for the first time and develop a novel Fe-SnS 2 /SnO 2 @NF catalyst, which represents the first application of such a catalyst in NRR. Furthermore, density functional theory (DFT) calculations reveal that the introduced Fe promotes charge redistribution at the SnS 2 /SnO 2 interface, thereby enhancing the interfacial electric field. This amplified electric field plays a key role in activating orbital interactions and regulating electron distribution, thereby greatly facilitating the conversion of N 2 to NH 3 via a distal binding mechanism. This effect has been rarely reported in previous studies. Notably, the Fe-SnS 2 /SnO 2 @NF catalyst achieves an ammonia yield of 39.05 ± 2.27 μg h −1 cm −2 and a Faradaic efficiency (FE) of 29.52 ± 0.71% at room temperature, surpassing the NRR activity of other Sn-based materials. This work represents a significant advancement in understanding the role of doping strategies in enhancing the interfacial electric field of heterostructures and provides valuable insights into their effectiveness for nitrogen fixation.

This study reports a facile synthesis of Au-modified Nano-SnS2 composites through a combined water-thermal and in situ chemical reduction method, aimed at advancing low-temperature gas sensing technology. Comprehensive structural analyses using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy confirmed that incorporation of Au nanoparticles significantly alters the nanostructure. The results reveal that optimal Au loading at 0.5 wt% refines the crystallite size from approximately 25 nm to 20–23 nm, while uniformly distributed Au particles with diameters of 3–5 nm effectively form Schottky junctions that enhance interfacial charge transfer. Gas sensing measurements demonstrate that the sensor response increases from 4.7 at 1 ppm to 22.6 at 10 ppm NO2, and a linear correlation (R2 = 0.998) was observed in the lower concentration range of 1–4 ppm. Furthermore, the optimal operating temperature decreased from 140°C for the unmodified sensor to 120°C, contributing to reduced power consumption. The transient response characteristics also improved markedly, with a response time of 42 s and a recovery time of 127 s, in contrast to 220 s and 520 s for the pristine material. Long-term stability tests over 40 days revealed less than 4% variation in sensor performance, and selectivity experiments confirmed a strong preference for NO2 over other interfering gases. Overall, the synergistic effects of Au-induced electronic sensitization and catalytic activity result in enhanced sensitivity, faster kinetics, and excellent durability. These significant findings offer valuable insights for designing highly efficient sensors for environmental monitoring, paving the way for future sensor technology.

A BiOI/SnS2 p–n junction is prepared by depositing BiOI particles on flowerlike SnS2 flakes. The heterojunction formed between p-type BiOI and n-type SnS2 brings greatly improved photocatalytic activity compared with pure SnS2 or BiOI in the degradation of Rhodamine B dye under visible light and sunlight irradiation. The improved photocatalytic performance is explained by the synergetic effects of the formation of a p–n junction between BiOI and SnS2. The migration of photogenerated carriers can be promoted by the electric field established at the heterojunction interfaces, leading to effective separation of the photogenerated electron–hole pairs and reduced electron–hole recombination. The BiOI/SnS2 heterojunction will find promising applications in photocatalysis and solar energy conversion.

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.

Potassium-ion batteries (PIBs) are promising candidates to substitute lithium-ion batteries (LIBs) as large-scale energy storage devices. However, developing suitable anode materials is still a great challenge that has limited the anticipated application of PIBs. Herein, the interlayer expanded SnS 2 nanocrystals anchored on nitrogen-doped graphene nanosheets (SnS 2 @NC) are synthesized following a facile one-step hydrothermal strategy. Relying on the exquisite nanostructure with larger interlayer spacing, the K + ions diffusion and charge transfer will be accelerated. In addition, the intense coupling interaction between nitrogen-doped graphene nanosheets and SnS 2 can endow a sturdy nanostructure, avoiding the collapse and aggregation of SnS 2 nanocrystals upon cycling. Based on the above merits, the as-prepared SnS 2 @NC anode exhibits improved electrochemical performanc (desirable rate capability of 206.7 mAh g −1 at 1000 mA g −1 and advanced cyclic property of 262.5 mAh g −1 , while after 100 cycles at 500 mA g −1 ). More importantly, multistep reactions of K + storage mechanism combining with intercalation, conversion and alloying reactions are clearly illustrated by combined in-situ XRD measurement and ex-situ TEM detection. This strategy of enhancing K + storage performances has a great potential for other electrode materials. Graphical Superlative : The unique interlayer expanded SnS 2 nanocrystals anchored on nitrogen-doped graphene nanosheets are exquisitely constructed and used as potassium-ion battery anode with enhanced specific capacity and long cyclic stability. This rationally strategy may provide further applicability in other energy storage systems.

The development of photoelectric devices for high integration and miniaturization in the semiconductor industry can be pushed forward by the thriving research of two-dimensional layered metal dichalcogenides (2D-LMDs). SnS2 nanosheets have an evident photoresponse to both ultraviolet and partial visible light, but only with a fair photoelectric performance limited by their atomic-layer thickness. Here, we report a convenient and simple method to dramatically enhance the electrical and photoelectric performance of the SnS2 flake. By integrating SnS2 with Au plasmonic nanostructures, the photocurrent (Iph) increased by over 20 times. The corresponding responsivity (R), light gain (G), and detectivity (D*) have been improved by ∼2200%, 2200% and 600%, respectively. The responsivity and detectivity of the Au NPs-SnS2 field-effect transistor (FET) at 532 nm are 1125.9 A W−1 and 2.12 × 1011 Jones. Though atomically thin, the hybrid SnS2 photodetector, benefiting from local surface plasmonic resonance, achieves an excellent photoelectric performance that is not usually possible with a pristine SnS2-only device.

SnS 2 , a promising candidate for high-performance photodetectors (PDs), encounters challenges as high dark current and poor stability in practical applications. Herein, pristine SnS 2 (P 0 SS) and phosphorus (P) doped SnS 2 single crystals (P 1 SS, P 2 SS) are synthesized and implanted into devices with an asymmetric electrode contact structure, which demonstrate self-powered photoelectric responses. At 0 V, P-doped SnS 2 PDs exhibit significant broadening of the response spectrum. Meanwhile, the P 2 SS device achieves the highest responsivity of 57.4 mA W −1 and specific detectivity of 1.22 × 10 11 Jones at 365 nm, and has superior long-term cyclic stability. At 1 V, the dark current of P 2 SS is significantly lowered, and the on-off ratio is about two orders of magnitude higher than those for the other two at 515 nm. The self-powered phenomenon of the three PDs here is attributed to the asymmetric Schottky barriers at the two gold/SnS 2 interfaces of the source and drain electrodes. The enhanced photoelectric response of the P-doped SnS 2 PDs can be due to the lowered conductivity and higher exciton separation efficiency by the compensation doping. This work offers a promising pathway for optimizing the optoelectronic detection capability of future portable devices.

Using Sn 2+ instead of Sn 4+ as Sn source, H 2 O 2 as oxidizer, and l -cysteine as sulphur source and structure-directing agent, hierarchical SnS 2 nanostructure built with the thickness of 10 nm nanosheets was successfully synthesized by a green hydrothermal process. The morphology and structure of the products were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) with energy-dispersive X-ray spectrometer (EDS) and Elemental mapping, Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The as-prepared nanostructured SnS 2 nanomaterials were tested for adsorption of Rhodamine B (RhB) from aqueous solution. The effects of contact time, adsorbent dosage and initial concentration were investigated in detail. The adsorption kinetic data were well fitted to the pseudo-second-order model and the equilibrium adsorption data were well described by the Langmuir isotherm model, with a maximum capacity of 200.0 mg g −1 . This study provides a novel approach to obtain metal sulfide nanostructures using low-valence metal salts.

Layered metal sulfides are considered as promising candidates for potassium ion batteries (KIBs) owing to the unique interlayer passages for ion diffusion. However, the insufficient electronic conductivity, inevitable volume expansion, and sulfur loss hinder the promotion of K-ion storage performance. Herein, few-layered Ti 3 C 2 T x nanosheets were selected as the multi-functional substrate for cooperating few-layered SnS 2 nanosheets, constructing SnS 2 /Ti 3 C 2 T x hetero-structural nanosheets (HNs) with the thickness as thin as about 5 nm. In this configuration, the formed Ti-S bonds provide robust interaction between SnS 2 and Ti 3 C 2 T x nanosheets, which hinders the agglomeration of SnS 2 and the restack of Ti 3 C 2 T x , endowing the hybrid material with robust nanostructure. Thus, the shortcomings of the SnS 2 anode are muchly relieved. In this way, the as-prepared SnS 2 /Ti 3 C 2 T x HNs electrode delivers reversible capacities of 462.1 mAh g −1 at 0.1 A g −1 and 166.1 mAh g −1 at 2.0 A g −1 , respectively, and a capacity of 85.5 mAh g −1 is remained even after 460 cycles at 2.0 A g −1 . These results are superior to those of the counterpart electrode, confirming aggressive promotion of K-ion storage performance of SnS 2 anode brought by the cooperation of Ti 3 C 2 T x , and presenting a reliable strategy to improve the electrochemical performance of sulfide anodes.
