Ruthenium (Ru)-based electrocatalysts have garnered considerable attention due to their low water dissociation barrier, exceptional H adsorption strength and relatively lower cost in platinum-group metals catalysts. while the strong oxyphilic property of Ru leads to excessive adsorption of hydroxyl species (OHad) generated from the water dissociation process. However, it remains challenging to introduce another oxophilic species to weaken the adsorption of OHad while avoiding the coverage of active sites and ensuring the subsequent re-adsorption and desorption of water. Herein, we reported an ordered Ru3Sn7 intermetallic compounds (IMCs)/acetylene black (AB) electrocatalyst. The highly ordered structure exposed abundant Ru active sites and atomically adjacent Sn oxophilic sites enable uniform distribution of both H and OH adsorption sites and preventing the coverage of Ru site. The prepared Ru3Sn7 IMCs/AB promotes interfacial water adsorption/dissociation by optimizing OH adsorption ability. As a result, Ru3Sn7 IMCs/AB catalyst delivers exceptional HER performance, achieving a low overpotential of 9 mV at 10 mA cm-2 and long-term durability over 150 hours. CO-stripping tests, in situ electrochemical Raman spectroscopy and DFT calculations revealed that synthesized ordered Ru3Sn7 IMC effectively modulates the OH adsorption and improve the adsorption/desorption of interfacial water

Sn-Beta zeolite is a versatile heterogeneous Lewis acid catalyst. Herein, we report a fluoride-free aerosol-assisted hydrothermal synthesis of plate-like Sn-Beta zeolite, which overcomes the environmental problems caused by traditional fluorinated hydrothermal method. The synthesis process, after the optimation by varying seed types, seed loadings, templating agent amounts, and crystallization times, results in the plate-like Sn-Beta zeolite with high relative crystallinity and mesoporous pore volume. Furthermore, the zeolites synthesized using this method exhibit superior catalytic performance in the Baeyer-Villiger oxidation of 2-adamantanone as compared to the sample synthesized by traditional fluoride-assisted hydrothermal method. The physicochemical characteristics of the two samples have been systematically compared. The enhancement of catalytic performance can be ascribed to their greater external surface area, which is more accessible to large molecules.

Tin oxide is widely recognized as a promising candidate for the electrochemical synthesis of formate from CO2. However, challenges such as suboptimal performance and a limited understanding of the reaction mechanisms persist. In this study, we developed an integrated electrode by optimizing a hierarchical metal–metal oxide nanoarray via a combination of hydrothermal synthesis and electrodeposition. This design enables direct growth of the catalyst on the current collector, eliminating the need for polymer binders. The constructed metal–loading structure effectively regulates the electronic structure of Sn and facilitates the formation of Snδ+ species, which thereby enhances the adsorption strength of *OCHO intermediate, significantly enhancing formate production. The resulting electrocatalyst, Bi–Sn(In)O, demonstrates a Faradaic efficiency (FE) of 83.66% for the reduction of CO2 to formate, with a maximum production rate of 768.12 μmol·h–1·cm–2 and a current density of 54.45 mA·cm–2. In situ infrared characterization and theoretical calculations reveal that local charge redistribution and the presence of high-valence Snδ+ improve the adsorption and stabilization of the crucial *OCHO intermediate, thereby lowering the energy barrier for HCOOH formation. Additionally, the integrated electrode design enables the exposure of more active sites, substantially increasing the electrochemical surface area and catalytic activity. This study offers valuable insights into the catalyst design for high-valence Snδ+ in CO2 reduction.

Building energy conservation through the development of transparent thermal insulation materials that selectively block near-infrared radiation while maintaining visible light transmittance has emerged as a key strategy for global carbon neutrality. WO3is a semiconductor oxide with near-infrared absorption capabilities. However, the limited absorption efficiency and narrow spectral coverage of pure WO3significantly diminish its overall transparent thermal insulation performance, thereby restricting its practical application in energy-saving glass. Therefore, this study successfully prepared Sn-doped WO3materials using a one-step hydrothermal method, controlling the Sn:W molar ratio from 0.1:1 to 2.0:1. Through evaluation of transparent thermal insulation performance of a series of Sn-doped WO3samples, we found that Sn:W = 0.9:1 exhibited the most excellent performance, with NIR shielding efficiency reaching 93.9%, which was 1.84 times higher than pure WO3. Moreover, this sample demonstrated a transparent thermal insulation index (THI) of 4.38, representing increases of 184% and 317%, respectively, compared to pure WO3. These enhancements highlight the strong NIR absorption capability achieved by Sn-doped WO3through structural regulation. When Sn doping reaches a certain concentration, it triggers a structural transformation of WO3from monoclinic to tetragonal phase. After reaching the critical solubility threshold, phase separation occurs, forming a multiphase structure composed of a Sn-doped WO3matrix and secondary SnO2and WSn0.33O3phases, which synergistically enhance oxygen vacancy formation and W6+to W5+reduction, achieving excellent NIR absorption through small polaron hopping and localized surface plasmon resonance effects. This study provides important insights for developing high-performance transparent thermal insulation materials for energy-efficient buildings.

A series of Sr 1 . 9 6 Sn 1 − x Si x O 4 :0.04Sm 3 + ( x = 0 , 0.1, 0.15, 0.2, 0.3, 0.4) were synthesized from solid-state reaction. The mechanoluminescence (ML) performance of Sr 1 . 9 6 SnO 4 :0.04Sm 3 + was greatly enhanced by partial Si 4 + substitution for Sn 4 + , and the sample of Sr 1 . 9 6 Sn 0 . 8 Si 0 . 2 O 4 :0.04Sm 3 + showed weaker afterglow and twice stronger ML intensity than that in Sr 1 . 9 6 SnO 4 :0.04Sm 3 + . The stress response of Sr 1 . 9 6 Sn 0 . 8 Si 0 . 2 O 4 :0.04Sm 3 + ranged from 250 to 1200 N, and its linearity was greatly restored. Particularly, it was very sensitive in the minimal stress response range. These properties of no load threshold for stress sensing and weak afterglow make Sr 1 . 9 6 Sn 0 . 8 Si 0 . 2 O 4 :0.04Sm 3 + superior to other excellent ML materials. The introduction of Si 4 + caused lattice distortion and promoted defect formation in the system. The trap level energy greatly increased and the trap depth changed, which enhanced the trap ability and therefore improved effectively the ML properties.

The development of efficient and cost-effective oxygen evolution reaction (OER) catalysts is critical for advancing water-splitting technologies. In this study, we report the synthesis of a Sn-doped NiFe layered double hydroxide (LDH) integrated with zeolitic imidazolate framework-67 (ZIF-67)-derived Co species (NiFe-LDH-Sn/ZIF-67) as an efficient catalyst for the OER. The doping of Sn into NiFe-LDH enhances the electronic conductivity and optimizes the active sites for the OER. Concurrently, the introduction of ZIF-67 promotes structural stability and increases the surface area to 727 m2 g−1, fostering synergistic interactions between the components. The NiFe-LDH-Sn/ZIF-67 catalyst exhibits a significantly lower potential of 1.59 V vs. RHE at 10 mA cm−2 and a Tafel slope of 79 mV dec−1 in alkaline media. The study reveals that Sn doping facilitates the electron transfer process by reducing the equivalent series resistance (ESR) from 325 Ω to 161 Ω, while ZIF-67 improves charge redistribution and catalytic stability by 91.8% after 24 h. This study underscores the potential of combining LDH and metal–organic frameworks to design advanced catalysts for sustainable energy applications.

Electrodeposition is a simple and rapid method for the preparation of thin-film materials, allowing catalytic materials to be directly deposited onto substrates, thereby eliminating the need for binders. Compared with bulk materials, two-dimensional thin films possess a higher specific surface area. The incorporation of Ga in Sn-based alloy materials can effectively expose active sites, thereby enhancing the catalytic performance for CO 2 electroreduction. Doping with rare-earth elements such as cerium can induce the formation of oxygen vacancies and defect sites, or modulate the electronic structure of the catalyst surface. These modifications enable independent regulation of the adsorption energy of various intermediates, effectively lowering reaction energy barriers and improving catalytic efficiency. In this work, Ga-Sn-Ce electrodes were synthesized via electrodeposition in a deep eutectic solvent composed of choline chloride and urea, and subsequently applied to CO 2 reduction. The GaSnCe0.6 electrode exhibited excellent selectivity toward formic acid at −0.99 V vs. the reversible hydrogen electrode, achieving a Faradaic efficiency of 92 %. Compared with previously reported Ga-Sn alloys, the introduction of Ce resulted in a positive shift of 250–270 mV in the optimal reduction potential for formic acid production from CO 2 .

Eco-friendly CsSnI 3 -based perovskite light-emitting diodes (PeLEDs) with the emission peak extending to the near-infrared-II (NIR-II) region hold tremendous potential for applications in biological monitoring, night vision, and optical communications. However, the various defects caused by the instability of Sn 2+ within the CsSnI 3 film, and the non-equilibrium carrier injection rate in the devices are the two major factors that limit the device performance. Here, we report high-performance NIR-II CsSnI 3 -based PeLEDs achieved by employing functional sulfaguanidine (SG) molecules. Due to the strong S═O─Sn coordination bonds, NH 2 ···I − hydrogen bonds could be formed between CsSnI 3 and SG, which effectively eliminated various Sn(II)-related defects in the CsSnI 3 film. Moreover, the SG molecules significantly improved the morphological uniformity and regulated the carrier injection balance, resulting in more balanced carrier injection that enhanced the effective radiation recombination rate. Consequently, the optimized CsSnI 3 -SG PeLEDs achieved a breakthrough external quantum efficiency (EQE) of 8.1%, which is the highest efficiency reported for CsSnI 3 -based PeLEDs to date.

In the fields of nuclear engineering and solar thermal utilization, low melting point alloys with excellent thermal conductivity and heat transfer performance have attracted extensive research as a new generation of heat transfer fluids, leading to many fundamental and important application issues. This study investigates the high-temperature corrosion behavior of Sn-50Bi-2Zn (wt.%) heat transfer alloy against 304 stainless steel (304), 310S heat-resistant steel (310S), and 20 carbon steel (20C) at 600 °C. Theoretical analysis, based on Fick’s diffusion law, and experimental measurements reveal significant differences in corrosion severity. After 473 h, 20 carbon steel exhibited the lowest corrosion layer thickness (0.07 mm), while 310S suffered the most severe corrosion (1.50 mm), exceeding 304SS (0.83 mm) by 81%. Diffusion coefficients derived from Sn penetration depths further quantified these trends: D310S = 2.51 × 10−7mm2/s (6.8 × higher than 304: 3.7 × 10−8mm2/s) and D20C = 2.87 × 10−10mm2/s (128 × lower than 304SS). XRF analysis confirmed the dissolution of steel components into the molten alloy, with Fe, Cr, and Ni content increasing to 0.382 wt.%, 0.417 wt.%, and 0.694 wt.%, respectively, after 480 h. These results underscore the critical role of Ni content in accelerating Sn/Zn diffusion and pore formation, providing actionable insights for material selection in high-temperature heat transfer systems.

The instantaneous nucleation of Sn originating from the uncontrolled diffusion of Sn 2+ ions typically forms large, electrochemically inactive “dead Sn” that severely constraints the plating/stripping reversibility of Sn anode for acidic aqueous batteries. Herein, nanoscale spatial confinement of Sn 2+ ions is realized in SnSO 4 electrolyte by strategically dictating spontaneous assembly of nanomicelles with amphipathic sulfolane. The as-constructed locally heterogeneous environment ensures the sustainable release of Sn 2+ ions, which reprograms the nucleation manner from instantaneous to progressive modes. The consequent progressive formation of Sn nuclei triggers size refinement of electrodeposited Sn, thereby alleviating the “dead Sn” issue. Meanwhile, the reaction competitivity of Sn 2+ reduction over hydrogen evolution side reaction is effectively strengthened as the consecutive hydrogen bonding network among bulk water is disrupted by the micellar structure. Consequently, Sn anode exerts an unprecedently high average Coulombic efficiency of 99.97% and witnesses a prominent life span extension from 710 to 8400 h (~ 11-fold enhancement). In a dual-plating configuration, the Sn||Mn full battery delivers a 1.6 V discharge plateau and sustains 790 cycles, demonstrating practical feasibility. Our findings underscore the decisive role of the very initial nucleation behavior in regulating metal electrochemistry, applicable to other multivalent anodes.

Bimetallic catalysts are ideal candidates for boosting electrochemical CO2 reduction reaction (CO2RR). However, these catalysts have largely relied on tedious synthesis technology and play electrolytic role with the help of a metal substrate or gas diffusion electrode. Herein, noble metal-free In–Sn nanoparticles (NPs) with a core–shell structure that contains a hybrid In–Sn core and native Sn-doped In2O3 shell have been successfully grown on the copper foam by the potential-driven volume diffusion strategy. These NPs which spontaneously result in the formation of the In–Sn bimetallic interface by adjusting the element composition significantly boost the yield of CO2 reduction into formate over a wide potential window (−0.77 to −1.17 V versus reversible hydrogen electrodes) compared with pure single-metal counterparts. The optimized In–Sn NPs deliver a great partial current density of 57.6 mA cm–2 and high faradaic efficiency of 97.0%, a remarkable performance in comparison to the state-of-the-art reported bimetallic catalyst. Such excellent performance is revealed via in situ Raman analyses and theoretical calculations, indicating that the unique structure of In–Sn NPs with the In–Sn bimetallic interface favorably regulates the reaction dynamics and facilitates the adsorption of the *OCHO intermediate.

Sodium-ion battery (SIB) is regarded as the next generation of large-scale energy storage systems, but it still faces problems such as low energy density, severe expansion/contraction of electrode volume, and poor cycle performance. Herein, necklace-like Sn-MOF@PAN fibers are prepared by the electrospinning method and then carbonized into Sn-C necklace paper as the binder-free cathode in an SIB. In each bead, Sn nanoparticles are wrapped by a porous carbon shell. The morphology and composition of the necklace-shaped Sn@C nanofibers are optimized by adjusting the ratio of Sn-MOF/PAN in the precursor. Sn@C with the optimal composition has a high specific capacity of 207 mAh g −1 even at a high current density of 2 A g −1 and maintains a specific capacity of 327 mAh g −1 after 100 cycles at a current density of 100 mA g −1 . This research provides a high-performance flexible electrode for SIBs.
