Metal halide perovskite materials have demonstrated considerable potential as gain media for laser diodes. However, current research on perovskite lasers predominantly focuses on the visible light region. The development of near-infrared perovskite lasers with emission wavelengths beyond 850 nm remains a significant challenge. Herein, fully solution-processed near-infrared perovskite lasers with tunable emission wavelengths spanning from 872 to 948 nm are presented. By controlling the crystallization time of the FASnI 3 perovskite films, near-infrared lasing at room temperature without external cavities is realized. Through modulating the dimensions of the perovskite films via the incorporation of a large cation PEA + , quasi-2D perovskites with adjustable lasing wavelengths and enhanced stability are successfully developed. These findings provide a novel approach for the fabrication of near-infrared lasers, which will facilitate the advancement of lead-free perovskite lasers.

Tandem catalysis reaction, which integrates two consecutive steps into a single one, can efficiently eliminate the separation of intermediate products, shortening the reaction time and decreasing energy expenditure. Therefore, the development of an efficient method for catalyzing tandem conversion of alkenes to prepare 1,2-diols is extremely fascinating. In this work, we reported the hydrothermal synthesis of tin-tungsten oxide catalysts at different pH values and their application as bifunctional catalyst for the one-pot tandem catalysis of alkenes to 1,2-diols. The SnWO 4 catalyst prepared at pH = 5 revealed the best tandem conversion performance and could attain a 95.4 % of cyclohexene conversion as well as a 77.2 % of 1,2-cyclohexanediol selectivity within 4 h of reaction. A possible mechanism corresponding to the tandem catalytic conversion of cyclohexene into 1,2-cyclohexanediol over SnWO 4 catalyst was proposed. Moreover, quenching experiments, density functional theory (DFT) calculations and in-situ infrared characterizations were further utilized to verify the reaction mechanism. Sn(II) could stabilize tungstate through the formation of W-O-Sn bonds and effectively reduced the energy of tungsten active centre binding to hydrogen peroxide, promoting the tandem catalysis reaction of cyclohexene to 1,2-cyclohexanediol. In addition, the one-pot tandem catalysis system could be further extended to the majority of linear and cyclic alkene substrates. This work can give a basis for the development of more green and efficient tandem conversion reaction of alkenes into 1,2-diols.

Escalating carbon dioxide (CO 2 ) emissions and widespread freshwater scarcity represent critical challenges to global environmental sustainability. This study addresses both issues simultaneously by coupling electrochemical CO 2 reduction (CO 2 RR) with seawater desalination using a novel N-SnPc/NRGO nanocomposite. This material was fabricated by anchoring tin-phthalocyanine nanostructures (N-SnPc) onto nitrogen-doped reduced graphene oxide (NRGO). The unique architecture enhances electrical conductivity and increases the exposure of active sites, optimizing electron transfer and reactant mass transport, thereby boosting CO 2 RR performance towards formate production. The optimized N-SnPc/NRGO composite (1:2 mass ratio) achieved a high formate Faradaic efficiency (FE formate ) of 86.0 % at −0.84 V vs. reversible hydrogen electrode (RHE), alongside excellent long-term operational stability. Density functional theory (DFT) calculations revealed that NRGO modification enhances the conductivity of SnPc and modulates the p -band center of the Sn N 4 sites, promoting CO 2 adsorption and rationalizing the elevated CO 2 RR activity. Furthermore, when integrated into an electrochemical desalination device, the N-SnPc/NRGO (1:2) cathode facilitated a rapid salt removal rate (SRR) of 778 μg cm −2 min −1 while maintaining an 83.3 % FE formate . Processing natural seawater, the device achieved freshwater standard with a total salt removal efficiency of 99.7 %. This work introduces a promising strategy for designing cost-effective, high-performance Sn-based CO 2 RR electrocatalysts and presents an innovative approach to tackling water resource challenges through integrated electrochemical systems.

Lead halide perovskites (LHPs) have superior luminescent properties, but their toxicity hinders their commercialization, arousing interests in tin halide perovskites as environmentally friendly substitutes for LHPs. Herein, we synthesized a series of two-dimensional tin halide perovskite ODASnBr 4-x I x (ODA denotes 1,8-octanediammonium, X = 0, 1, 2, 3, 4) microcrystals via an aqueous-phase method. The differences between ODASnI 4 and ODASnBr 4 in luminescent properties and morphological characteristics were systematically discussed for the first time and attributed to light-driven ligand-to-metal charge transfer. The prepared ODASnBr 4 has a PL peak at 567 nm and a PL QY of 99%, and the white light-emitting diodes fabricated with ODASnBr 4 and commercial blue phosphors realized a luminous efficacy of up to 96.27 lm/W, which demonstrated the remarkable potential of ODASnBr 4 microcrystals for high-efficiency white light-emitting diode applications.

Oxide-coupled carbon-based composite materials, combining high conductivity and excellent electrocatalytic activity, are regarded as crucial host materials for achieving high-rate performance in lithium-sulfur batteries. However, the influence of oxide crystallinity on the electrochemical behavior of lithium polysulfides (LiPSs) remains largely unexplored, leaving the mechanism of interaction between crystallinity variations and catalytic activity insufficiently understood. In this study, we construct tin oxide with varying degrees of crystallinity on the surface of nitrogen-doped graphitized carbon materials (SnO 2 @NC). Utilizing confocal microscopy and in situ Raman spectroscopy, we visually demonstrate the transformation process of LiPSs, accurately identifying the positive facilitation of lithium polysulfide conversion by the changes in weak crystallinity. Through geometric phase analysis, it is revealed that weak crystallinity induces a 60 % variation in lattice strain, optimizing the adsorption energy of LiPSs, leading to superior sulfur retention effects and enhanced electrocatalytic activity. These findings enable the development of a stable sulfur-storage cathode (SnO 2 @NC-60 %/S) operating under high rates. This fundamental understanding of the inherent relationships provides a viable crystallographic modulation strategy for the design of multifunctional hosts in lithium-sulfur battery cathodes.

Owing to their distinct chemical and physical properties, mesoporous metal oxide semiconductors have shown great application potential in catalysis, electrochemistry, energy conversion, and energy storage. In this study, mesoporous crystalline SnO2 materials have been synthesized through an evaporation-induced co-assembly (EICA) method using poly(ethylene oxide)-b-polystyrene diblock copolymers as the template, tin chlorides as the tin sources, and tetrahydrofuran as the solvent. By controlling conditions of the co-assembly process and employing a carbon-supported thermal treatment strategy, highly ordered mesoporous SnO2 materials with a hexagonal mesostructure (space group P63/mmc) and crystalline pore walls can be obtained. The mesoporous SnO2 is employed for fabricating gas sensor nanodevices which exhibit an excellent sensing performance toward H2S with high sensitivity (170, 50 ppm) and superior stability, owing to its high surface area (98 m2/g), well-connected mesopores of ca. 18.0 nm, and high density of active sites in the crystalline pore walls. The chemical mechanism study reveals that both SO2 and SnS2 are generated during the gas sensing process on the SnO2-based sensors.

Summary The power conversion efficiency (PCE) of tin perovskite solar cells is impeded by the extremely poor resistance to oxidation and high density of intrinsic Sn vacancies. Herein, we grow a 2D-quasi-2D-3D Sn perovskite film using removable pseudohalogen NH 4 SCN as a structure regulator. This hierarchy structure remarkably enhances air stability resulting from the parallel growth of 2D PEA 2 SnI 4 as the surface layer. We then explore the hierarchy structure perovskite films in planar structural solar cells, which generate a PCE up to 9.41%. The device retains 90% of its initial performance for almost 600 hr. Our results suggest that adding removable NH 4 SCN in a perovskite precursor can significantly improve the stability and photovoltaic performance of Sn perovskite. This finding provides a powerful strategy to manipulate the structure of low-dimensional perovskite in order to enhance the performance of perovskite solar cells.

New tin-based metal-phosphine complexes of [Sn(OH) 4 (PPh 3 ) 2 ] and [Sn(OH) 2 (PPh 3 ) 2 ] have been successfully synthesized and used as supercapacitor electrodes for the first time, exhibiting a high specific capacitance, a good rate capability, and an excellent cycling stability. The specific capacitances (highest specific capacitance for tin-based materials) of 1204F g −1 and 764F g −1 for two samples at a current density of 1 A g −1 in 6 M KOH can respectively be achieved, and their capacitance retention remained at 95.1% and 89.2% even after 15,000 cycles at a current density of 10 A g −1 . Furthermore, a flexible quasi-solid-state asymmetric supercapacitor composed of Sn(OH) 2 (PPh 3 ) 2 and activated carbon was assembled and exhibited a specific capacitance of 290.6 mF cm −2 at a current density of 1 mA cm −2 . More importantly, this device also displayed excellent cyclic stability of ∼100% for 1800 cycles during the galvanostatic charge/discharge process at 5 mF cm −2 .

Two-dimensional conductive metal–organic frameworks (2D c-MOFs) hold great promise for electrochemical applications due to their π-conjugated structures and high conductivity, but their application in electrochemiluminescence (ECL) sensing remains largely unexplored. In this study, we synthesized 2D c-MOF Cu3(benzenehexathiol) nanosheets (CuBHT NSs) with lateral dimensions of 2–10 μm and a thickness of 24 nm and immobilized them on indium tin oxide (ITO) electrodes. This platform facilitated the first study of luminol’s cathodic ECL behavior. CuBHT NSs exhibited exceptional oxygen reduction reaction (ORR) catalytic activity, significantly enhancing the generation of reactive oxygen species (ROS) and thereby increasing the luminol’s cathodic ECL response. Mechanistic studies confirmed that unsaturated Cu sites in CuBHT play a crucial role, as Uric acid (UA) can bind to unsaturated Cu sites, inhibiting ROS production. This outcome enabled a highly sensitive and selective ECL sensor for UA with a wide linear range (10 nM–0.1 mM) and a low detection limit (3.5 nM, S/N = 3). The sensor was successfully applied to detect UA in serum samples.

The chemical recycling of waste poly(L-lactic acid) (PLLA) into its monomer, L-lactide, offers a promising strategy for establishing a circular economy for PLLA-based polymers. However, conventional approaches typically require high reaction temperatures and suffer from significant side reactions, thereby hindering the efficient recycling of waste PLLA. In this study, we present a low-temperature, continuous depolymerization process for waste PLLA, catalyzed by stearyl alcohol (StOH) and stannous octanoate (Sn(Oct) 2 ) at a mild temperature of 165 °C. This system achieves an L-lactide yield of 99.31 % and purity of 98.02 % (ee = 99.73 %). Characterization of the reaction mechanism, supported by density functional theory (DFT) calculations, reveals that StOH displaces the octanoate ligands in Sn(Oct)₂ to form tin(II) octadecyl alkoxide. This nucleophilic species interacts with the carbonyl groups of PLLA, promoting chain scission via ligand-assisted attack. The mechanism reduces the energy barrier for backbiting reactions, thereby enhancing the rate of L-lactide formation. This method exhibits strong practical viability, achieving a 97 % yield from real-world PLLA waste and selectively degrading PLLA in mixed plastic streams to enable efficient separation. Furthermore, a simplified continuous processing system was developed, demonstrating stable and sustained PLLA degradation. This work provides an innovative and scalable strategy for sustainable PLLA chemical recycling under mild conditions.

An efficient and durable oxygen evolution reaction (OER) electrocatalyst consisting of TiN @ Co 5.47 N is constructed by the integration of plasma nitriding and a delicate atomic layer deposition (ALD) Co x N process. Representative results of comprehensive study are: 1) the material is electrocatalytically active in universal medium. The OER overpotentials are 398, 248, and 411 mV in acidic, basic, and neutral electrolyte, respectively, at a current density of 50 mA cm −2 ; 2) the material records an impressive long-term stability of continuous catalysis for 1500 h, during which the overpotential increases by only 1.3%. The synergistically electronic interaction between TiN and ALD Co 5.47 N, as well as a protective yet active CoTi layered double hydroxides (CoTi LDH) layer formed simultaneously at the interface/surface of TiN @ Co 5.47 N during the electrocatalytic process, is speculated to be responsible for the superior OER performance; 3) the surface Co atoms other than Ti of CoTi LDH, exhibit electrocatalytic activity with dramatically low overpotential based on density functional theory calculations.

Graphical Al, Ga, and In are doped into SnO2 through the hydrothermal method, leading to changes in its bandgap and consequently improving the photocatalytic capability of SnO2. Tin oxide, particularly tin dioxide (SnO₂), exhibits excellent potential as a photocatalyst in wastewater treatment. Tin oxide nanocomposites were synthesized via a liquid-phase method using tin tetrachloride pentahydrate as the precursor and Al 3 ⁺, Ga 3 ⁺, and In 3 ⁺ ions as dopants. The samples were characterized by XRD, SEM, UV–vis spectroscopy, and so on. SEM images revealed that the doped nanoparticles formed denser aggregates with irregular coarse-cubic morphologies. XRD patterns of Al-, Ga-, and In-doped SnO₂ showed no impurity peaks, confirming their high crystallinity and phase purity. Doping modifies the energy band structure and introduces impurity levels, thereby enhancing visible-light absorption and inducing a redshift. These observations were supported by density functional theory (DFT) calculations. Compared to pure SnO₂, the doped SnO₂ demonstrated significantly higher photocatalytic activity, achieving an 88% degradation rate of rhodamine B after 150 min of irradiation—a 70% improvement over undoped SnO₂ (26%). This study highlights the potential of doped SnO₂ nanomaterials as efficient organic pollutant degraders in wastewater treatment.
