Antimony (Sb) based compounds such as Sb 2 O 3 and Sb 2 S 3 have shown promises in electronics, catalysis and sensing devices. Their functional performances can be further improved by integration with other materials to from composites or heterostructures, which however, usually require tedious procedures with poor morphology control. Herein, we realized direct hydrothermal synthesis of Sb 2 O 3 /SnO 2 heterostructures and Sb 2 S 3 /SnS 2 heterostructures by using liquid-phase exfoliated two-dimensional (2D) Sb nanoflakes as precursors. Compared to directly using SbCl 3 salt as the reactant, using the Sb nanoflakes enabled the slow release of Sb 3+ ions which benefited the better controlled nucleation and growth of Sb 2 O 3 (or Sb 2 S 3 ) acting as growth templates for the further deposition of SnO 2 (or SnS 2 ). As a demonstration, the as-prepared Sb 2 S 3 /SnS 2 heterostructures were employed for photocatalytic methylene blue (MB) degradation, which exhibited a faster degradation rate compared to Sb 2 S 3 or SnS 2 alone. Our work offers an alternative strategy with elemental 2D materials as precursors for the preparation of heterostructured functional materials.

Tungsten bronze is an effective near-infrared (NIR) shielding material for fabricating energy-saving smart windows. While high-performing NIR-shielding glasses can be fabricated by coating a tungsten bronze film on window glasses, these glasses suffer a short lifespan due to the adhesion and degeneration of film. In this work, we show that tungsten bronze-like material Na5W14O44 can be distributed in the bulk glass matrix during the facile melt-quenching glass fabrication process under an air atmosphere, overcoming the limitations of film-based glasses. X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy confirmed the presence of tungsten bronze-like Na5W14O44 functional units in the SiO2–B2O3–NaF glass matrix. The addition of a small amount of H2WO4 and Sb2O3 is critical for the formation of Na5W14O44 functional units because H2WO4 provides W for Na5W14O44, and Sb2O3 acts as a reducing agent that helps the formation of W5+ in Na5W14O44 under an air atmosphere. Furthermore, the NIR-shielding ability can be tuned by adjusting the concentration of Sb2O3 in the range of 0–1.5 mol % and of H2WO4 in the range of 4–6 mol %. The optimized composition containing 1.25 mol % of Sb2O3 and 5 mol % of H2WO4 exhibits excellent NIR-shielding ability (ΔT = 62.8%), high visible light transmittance (Tmax = 67.7%), and excellent thermal insulation. This performance is comparable to cesium tungsten bronze film-based glasses and much better than soda lime glass and ITO glass under sun irradiation. This study sheds light on fabricating energy-saving windows in a simple and cost-effective way with flexibility for fine tuning of NIR-shielding performance.

The S-doped Sb 2 O 3 nanocrystals were successfully synthesized using SbCl 3 and thioacetamide (TAA) as precursors via a facile one-step hydrothermal method. The effects of pH of the precursor reaction solution on the product composition and property were determined. The results indicated that the doping amount of S could be tuned by adjusting the pH of the precursor solution. Furthermore, the S entered into the interstitial site of Sb 2 O 3 crystals as S 2− , which broadened the absorption wavelength range of the Sb 2 O 3 nanocrystal. The S-doped Sb 2 O 3 exhibited an excellent visible-light-driven photocatalytic activity in the decomposition of methyl orange and 4-phenylazophenol. Last, a possible photocatalytic mechanism of the S-doped Sb 2 O 3 under visible light irradiation was proposed.

A novel Sb 2 O 3 /Sb 2 S 3 /FeOOH photoanode was fabricated via a simple solution impregnation method along with chemical bath deposition and post-sulfidation. The X-ray diffractometry, Raman measurement, and X-ray photoelectron spectroscopy show that the Sb 2 O 3 /Sb 2 S 3 /FeOOH thin films are successfully prepared. SEM−EDS analyses reveal that the surface of Sb 2 O 3 /Sb 2 S 3 thin films becomes rough after the immersion in the FeCl 3 solution. The optimized impregnation time is found to be 8 h. The FeOOH co-catalyst loaded Sb 2 O 3 /Sb 2 S 3 electrode exhibits an enhanced photocurrent density of 0.45 mA/cm 2 at 1.23 V versus RHE under simulated 1 sun, which is approximately 1.41 times compared to the photocurrent density of the unloaded one. Through the further tests of UV−Vis spectroscopy, the electrochemical impedance spectra, and the PEC measurements, the enhancement can result from the increased light-harvesting ability, the decreased interface transmission impedance, and the remarkably enhanced carrier injection efficiency.

MoS 2 –Sb 2 O 3 coating is commonly used as solid lubricant for titanium alloys , but the wear-resistance performance is still limited. Core-shell annealed nanodiamond (AND) particle is used as reinforcement for MoS 2 –Sb 2 O 3 coating on Ti6Al4V substrate treated by plasma electrolytic oxidation (PEO) and laser surface texturing (LST). The incorporation of AND particles into the MoS 2 –Sb 2 O 3 coating results in a 39 % decrease in friction and significantly reduces wear on the composite coating . Structural transformation of AND particles to amorphous carbon and graphitic structure promotes the densification of top-layer coating, enhancing lubrication and wear-resistance. Change of contact stress by PEO-LST promotes the formation of dense tribofilm and re-orientation of MoS 2 . This study has implications for the development of solid lubrication coatings for aerospace applications through functional nanomaterials and targeted designed surfaces.

As an important member recently joining the family of two-dimensional dielectrics, the antimony oxide atomic thin layer exhibits extremely high dielectric constant and breakdown voltage, intriguing great enthusiasm to explore these novel physical properties for applications. Herein, transformation of chemical vapor deposition grown α-Sb2O3 flakes into α-Sb2O4 was achieved under ambient conditions using a near field heating effect provided by thin gold films. Flakes with a thickness of 4–42 nm can be fully transformed in 20 s with irradiation of a continuous-wave 532 nm laser. Such a short transformation time further allows laser patterning on α-Sb2O3 flakes with microscale spatial resolution. These results greatly enrich the knowledge of this novel 2D dielectric material and facilitate its application in atomic scale electronic devices.

Low-dimensional Sb2O3 holds great promise as an anode material for sodium-ion batteries (SIBs), but its scalable synthesis remains a challenge. Here, we report a green hydrothermal approach in surfactant-free pure water to fabricate ultrathin Sb2O3 nanobelts (NBs) via a multistage growth mechanism: (i) ultrasonic exfoliation of bulk Sb into quantum dots, (ii) dissolved oxygen-driven oxidation and self-assembly into nanoclusters, and (iii) temperature-controlled phase selection, yielding orthorhombic NBs at 80 °C with respect to cubic nanosheets at room temperature. This method is observed to achieve a mass conversion rate of over 32% for the target NBs with controlled dimensions. Furthermore, the Sb2O3 NBs exhibit an ultrathin thickness (<40 nm) along the [100] orientation, effectively mitigating volume expansion during cycling. Such an anode material delivers a discharge capacity of 443.1 mAh·g–1 at 0.1 A·g–1 over 150 cycles, demonstrating an outstanding long-term cyclability. The current work provides a scalable and eco-friendly synthesis strategy for low-dimensional Sb2O3 nanostructures, offering new insights into their application in SIBs and other energy storage devices.

Copper antimony sulfur (CuSbS 2 ) possesses a band gap of about 1.5 eV, high absorption coefficient of > 10 4 cm −1 and abundant compositions, which is considered as one of the potential photovoltaic absorbers. In this work, we propose a facile ion-exchange assisted chemical bath deposition (IEACBD) method, which uses Cu + to replace Sb 3+ from the matrix of Sb 2 S 3 and then combine into CuSbS 2 alloy. Through systematic study, we found that this ion-exchange is a simultaneous interdiffusion process of Cu + and Sb 3+ ions, which enables a uniform mixture of those two elements. But it also inevitably produces a Sb 2 O 3 by-product on the surface of the film because of the alkaline environment of this chemical bath. To further remove it, we introduce a mild etching process with BDCA solution for Sb 2 O 3 and then obtain a high-quality CuSbS 2 . Finally, we assemble an inorganic CuSbS 2 solar cell with the architecture of FTO/TiO 2 /CdS/CuSbS 2 /Carbon/Ag, and delivering a photoelectric conversion efficiency of 0.75 %. This enriches the preparation method of CuSbS 2 thin film and also provides guidance for the synthesis of the similar multiple chalcogen compounds.

A silicon/antimony/antimony oxide/graphite@amouphous carbon (Si/Sb/Sb2O3/G@C) composite material was prepared successfully via a simple ball milling and high temperature calcination process. Its structural characterization showed that Si and Sb/Sb2O3 were dispersed into the graphite layer and coated with amorphous carbon. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) results revealed that Sb2O3 was partly reduced to Sb by carbon, which could improve its electronic conductivity. Besides, Si, Sb, Sb2O3 and carbon have different lithiation/delithiation voltage plateaus, which can act as a mutually buffering matrix, thus improving its electrochemical performance. Due to the high specific capacity, good electronic conductivity and stable cycling performance benefited from the Si/Sb/Sb2O3, Sb/G and G/C, respectively, as well as the mutually buffering matrix of all the active materials, the resulting composite electrode materials exhibit excellent electrochemical performance. The composite material exhibited good cycling performance (a stable reversible delithiation capacity of 567.8 mA h g−1 after 180 cycles), excellent rate capability (∼360 mA h g−1 and 280 mA h g−1 at current densities of 1000 mA g−1 and 2000 mA g−1, respectively) and decreased polarization resistance. This work demonstrates a facile and cost-effective approach to preparing composite materials with complementary advantages for use in high-performance Li-ion batteries.

Metallic Sb is deemed as a promising anode material for lithium ion batteries (LIBs) due to its flat voltage platform and high security. Nevertheless, the limited capacity restricts its large-scale application. Therefore, a simple and effective method to explore novel antimony trioxide with high capacity used as anode material for LIBs is imperative. In this work, we report a facile and efficient strategy to fabricate 1D hollow Sb 2 O 3 @TiO 2 composites by using the Kirkendall effect . When used as an anode material for LIBs, the optimal Sb 2 O 3 @TiO 2 composite displays a high reversible discharge capacity of 593 mAh g −1 at a current density of 100 mA g −1 after 100 cycles and a relatively superior discharge capacity of 439 mAh g −1 at a current density of 500 mA g −1 even after 600 cycles. In addition, a reversible discharge capacity of 334 mAh g −1 can also be obtained even at a current density of 2000 mA g −1 . The excellent cycling stability and rate performance of the Sb 2 O 3 @TiO 2 composite can be attributed to the synergistic effect of TiO 2 shell and hollow structure of Sb 2 O 3 , both of which can effectively buffer the volume expansion and maintain the integrity of the electrode during the repeated charge-discharge cycles.

Improving energy utilization efficiency is crucial to broadening the prospects in the field of electrochemical wastewater treatment. The electrochemical flow-through (FT) mode shows the potential prospect of high oxidation efficiency and low energy cost. In this study, based on the SnO2-Sb2O3 macroporous anode, we designed a multi-stage flow-through (MSFT) anode that significantly enhanced the organic removal performance than that of a conventional FT system. Accordingly, we first proposed the current reaction kinetics model that could appropriately describe the removal performance in the MSFT electrochemical oxidation process. The mass transfer impact of MSFT was also suitably evaluated by our model, which indicated that the MSFT could rapidly achieve the same diffusion flux for electrochemical oxidation limitations. The energy consumption per order of magnitude removal (EE/O) was below 0.12 kWh m–3 for low-concentration organics, which sharply decreased with an increase in the flow. For the simulation of low conductivity of water quality (∼439 μS cm–1), we found that the MSFT could obtain the voltage reduction of approximately 25% for saving energy without the extra electrolyte. Finally, we summarized the nominalized electron utilization performance of organic destruction on various electrochemical advanced oxidation anodes. The normalized removal rate of contaminants per current was greatly improved by the MSFT mode and our highly efficient anode. Notably, the MS design can prolong the anode usage lifetime. We anticipate that our work will provide design development for other anodic interfaces in the field of electrochemical wastewater purification applications.

Antimony-based electrode materials with conventional slurry-casting process still face great challenges such as tedious preparation process and unsatisfying cycling stability for sodium ion batteries (SIBs). Therefore, the design and fabrication of integrated electrodes with binder-free and even current collector-free are highly significant. Herein, we fabricated flexible Sb/Sb 2 O 3 -C nanofibers (NFs) films utilizing a facile combination of electrospinning technique and carbonization . Sb/Sb 2 O 3 nanoparticles are well embedded in carbon NFs with a fiber diameter of ca. 340 nm. The fabricated NFs films can be directly used as binder and current collector-free anodes for SIBs and exhibited high-capacity and long-lifetime cycles (385.6 mAh g −1 over 500 cycles). Ex situ SEM and TEM observations re-appear their intact fibrous network morphology and stable one-dimensional composite structures after hundreds of discharging-charging cycles, demonstrating that Sb/Sb 2 O 3 -C NFs film is a promising binder-free electrode for SIBs.
