A simple synthesis has been proposed for seaweed-like amorphous TiO 2-x modified Sb (a-TiO 2-x /Sb) composite nanowires as sodium-ion battery (SIBs) anodes by a dealloying method of Al-Sb-Ti alloys. Compared with other conventional methods, this method has the advantages of simple preparation, high yield and easy large-scale synthesis. It is excitingly discovered that a-TiO 2-x /Sb effectively alleviates volume changes and stabilizes the solid electrolyte interface (SEI). The a-TiO 2-x /Sb nanowires electrodes deliver outstanding electrochemical performance based on the synergistic effects, exhibiting a high reversible capacity of 591.9 mA h g −1 at 100 mA g −1 , stable cycling performance with a high capacity retention of 96.4% after 200 cycles and superior rate capability 382.2 mA h g −1 at 10,000 mA g −1 , which is very competitive among the reported Sb-based anodes.

It is urgent and essential to remove antimony from wastewater due to its potential carcinogenicity . In this paper, a nano ferric oxide (NFO) adsorbent was synthesized in a one-step low temperature calcination (150 °C) process. It presents a surprising self-acidification behavior, could automatically adjust the pH to around 4 from different intimal pH values (4–9), which enable it to efficiently remove more than 99% of Sb(V) from wastewater in a wide pH range. X-ray photoelectron spectroscopy analysis proved that the self-acidification function was originated from the hydrolyzation of surface Fe atoms on ferric oxide nanoparticles . The maximum adsorption capacity of this adsorbent is 78.1 mg/g which is 2–3 times higher than that of the samples obtained at higher temperatures (250 °C and 350 °C), and also its adsorption kinetic constant is ten times higher, which can be attributed to the larger surface areas and smaller sizes of ferric oxides synthesized at 150 °C. In the actual wastewater treatment , the effluent’s concentration after treatment can be maintained below the instrument detection limit even under low initial antimony concentration. We believe that this new adsorbent has great potential in the practical application in the treatment of Sb polluted wastewaters due to its simple synthesis, high efficiency, and low cost.

Both antimony selenide and antimony are promising anode materials for lithium-ion batteries. However, owing to the influence of the poor electronic conductivity of Sb 2 Se 3 and the large volume expansion of the two materials during the lithiation process, their electrochemical performance is limited and the practical application is restricted. In this work, for the first time, the hierarchical Sb 2 Se 3 and Sb particles fully encapsulated into carbon nanofibers (Sb 2 Se 3 /Sb/C nanofibers) have been in-situ synthesized by electrospinning followed by controlled annealing. Combining the advantages of high specific capacity of Sb 2 Se 3 , good electronic conductivities of Sb and C, and strong stability of C matrix, the Sb 2 Se 3 /Sb/C nanofibers electrode shows excellent lithium-storage performance. It achieves a high reversible capacity (764 mA h g −1 after 300 cycles at 0.1 A g −1 ), splendid ultralong cycling stability (429 mA h g −1 after 1000 cycles at 1 A g −1 ), and high rate capability (342 mA h g −1 at 5 A g −1 ). It demonstrates that Sb 2 Se 3 /Sb/C nanofibers are promising high-performance anode materials for lithium-ion batteries.

The pyrochlore-type material Co 2 Sb 2 O 7 @C was synthesized through high-temperature solid-state reactions. Co 2 Sb 2 O 7 and Co 2 Sb 2 O 7 @C were characterized by PXRD, XPS, SEM, EDS, and BET. At the current density of 200 mA g −1 , the first cycle discharge capacity of Co 2 Sb 2 O 7 @C is 1266 mAh g −1 . After 100 cycles, the specific discharge capacity can still reach 463 mAh g −1 , which is higher than the 76 mAh g −1 of Co 2 Sb 2 O 7 . With the increase in scanning rate, the contribution rate of the Co 2 Sb 2 O 7 @C pseudo-capacitor varies from 69.2 to 92.5%. The electrochemical performance is due to the conversion and alloying reaction of Li 3 Sb, the coating of amorphous carbon, and the contribution of pseudo-capacitance.

Platinum-based (Pt) catalysts are notoriously susceptible to deactivation in industrial chemical processes due to carbon monoxide (CO) poisoning. Overcoming this poisoning deactivation of Pt-based catalysts while enhancing their catalytic activity, selectivity, and durability remains a major challenge. Herein, we propose a strategy to enhance the CO tolerance of Pt clusters (Pt n ) by introducing neighboring functionalized guest single atoms (such as Fe, Co, Ni, Cu, Sb, and Bi). Among them, antimony (Sb) single atoms (SAs) exhibit significant performance enhancement, achieving 99% CO selectivity and 33.6% CO 2 conversion at 450 °C. Experimental results and density functional theory (DFT) calculations indicate the optimization arises from the electronic interaction between neighboring functionalized Sb SAs and Pt clusters, leading to optimal 5 d electron redistribution in Pt clusters compared to other functionalized guest single atoms. The redistribution of 5 d electrons weaken both the σ donation and π backdonation interactions, resulting in a weakened bond strength with CO and enhancing catalyst activity and selectivity. In situ environmental transmission electron microscopy (ETEM) further demonstrates the exception thermal stability of the catalyst, even under H 2 at 700 °C. Notably, the functionalized Sb SAs also improve CO tolerance in various heterogenous catalysts, including Co/CeO 2 , Ni/CeO 2 , Pt/Al 2 O 3 , and Pt/CeO 2 -C. This finding provides an effective approach to overcome the primary challenge of CO poisoning in Pt-based catalysts, making their broader applications in various industrial catalysts.

Nanosheet-assembled microspheres of tungsten oxide doped with antimony were synthesized via hydrothermal method . Sb doping changed the valency of W, promoted a partial crystal phase transition from orthorhombic to hexagonal, and modified the surface morphology . Further, WO 3 is an n-type semiconductor and is sensitive to gases above 100 °C. The Sb-WO 3 sensors in this work were p-type semiconductors from 25 °C to 65 °C, and exhibited excellent sensitivity, fast response and good recovery properties to NH 3 . At 35 °C, the detection limit of 1 at% Sb-WO 3 for ammonia was 200 ppb, and the sensor shows a good stability and selectivity toward several possible interferent . The substantially improved sensing performance of the Sb-WO 3 sensors at near room temperature could be mainly attributed to the change of the W valency promoted via Sb doping.

One-dimensional nanotubes are very useful for achieving excellent performance in lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to the fact that tubular structures can effectively alleviate the structural strain and shorten the ion diffusion length during repeated cycling. In this work, we report a Cu2Sb-mediated growth strategy to controllably fabricate highly uniform Sb nanotubes (NTs), as well as Cu@Cu2Sb and Cu2Sb@Sb composite NTs, via a facile galvanic replacement reaction using Cu nanowires (NWs) as sacrificial templates. Benefiting from their structural merits, the Sb NTs manifest excellent sodium storage performance with superior rate performance (286 mAh g–1 at 10 A g–1) and extraordinary cycling stability (342 mAh g–1 after 6000 cycles at 1 A g–1). Furthermore, a full cell with Sb NTs as anode and Na3(VOPO4)2F as cathode exhibits a high energy density (252 Wh kg–1) and high output voltage (2.7 V), revealing their significant application promise in the next-generation SIBs.

In order to recover the antimony from wastewater, a custom-designed fluidized-bed reactor (FBR) was employed to treat antimony-containing wastewater. By single-factor experiments, the effects of the solution pH, the molar ratio of [TA]/[Sb3+], the seed size and dosage, the up-flow velocity (U), and the hydraulic retention time (HRT) on antimony recovery were investigated based on the antimony removal and granulation efficiency. The optimum conditions for antimony recovery were obtained at pH 9.0, the molar ratio of [TA]/[Sb3+] of 2, 6 g/L of 13–38 μm Sb2O3as the fluidized seed, and the U and HRT of 42 m/h and 40 min, respectively; the antimony removal and granulation efficiency reached 95% and 91%, respectively. The granular products were analyzed by an X-ray polycrystalline diffractometer (XRD) and scanning electron microscopy (SEM) as cubic Sb2O3, widely used in various industries. The fluidized-bed reactor was operated continuously for 7 days, during which the antimony removal and granulation efficiency were stable at 96% and 93%, respectively. This study demonstrated the feasibility of the fluidized-bed granulation process for the recovery of antimony from wastewater. It provides a novel approach for retrieving and managing antimony-containing wastewater.

Antimony (Sb) is a competitive candidate for lithium ion batteries (LIBs) as anode material because of its high theoretical discharge capacity (660 mAh/g). However, it remains a challenge caused by the volume change in the process of charge and discharge, which would damage the Sb anode that lead to poor rate performance and low cycle stability. Herein, we report the synthesis of Sb@S–N–C nanocomposite as the anode material to solve the problem. First, SbSI nanowires with diameter of ∼10 nm were synthesized. Then the SbSI nanowires were coated with polypyrrole (PPy) to form SbSI@PPy core-shell nanowires. By thermal reduction of SbSI@PPy, Sb@S–N–C nanocomposite was formed. Using the Sb@S–N–C nanocomposite as the anode material, a capacity of 536 mAh/g was obtained in 100 cycles at 0.5 A/g. Excitingly, it also exhibited superior reversible and long-cycle non-decay stability with the capacity of 342 mAh/g in 2000 cycles at a high current density of 1A/g.

The high theoretical capacity of Sb-based intermetallic alloys makes them attractive potential anode materials for sodium-ion batteries (SIBs) with high energy density . However, their cycling stability is greatly restricted by the huge volumetric variations resulted from the intrinsic (de-)alloying mechanism. Herein, we demonstrate a unique lattice softening mechanism, which enables highly reversible sodium storage and stable cycling of the as-prepared Bi–Sb alloy/carbon nanofibers electrodes. Theoretical analyses show that the elastic modulus of Bi–Sb alloys is reduced whereas the toughness is enhanced by tuning the lattice chemistry of rhombohedral Bi–Sb alloys, which is of great importance in relieving the concentrated stress during the continuous (de-)sodiation processes. In-situ characterization and electrochemical evaluations demonstrate that the electrodes made of BiSb 3 /C nanofibers exhibit high anti-pulverization capability upon Na-cycling and extraordinary long-life cyclability. Specifically, a highly reversible capacity of 233.2 mAh g −1 at 2 A g −1 is achieved over 2500 cycles. Moreover, a full cell assembled with the pre-sodiated BiSb 3 /C anode and a Na 3 V 2 (PO 4 ) 3 /C cathode delivers a high reversible capacity of 333.2 mAh g −1 at 0.2 A g −1 over 200 cycles. This present work provides further understandings and new solution for developing high-performance alloying-based anodes for SIBs.

Antimony, as the anode of potassium ion batteries, has a satisfactory theoretical specific capacity (660 mAh g −1 ). However, the lattice expansion after potassization and insufficient conductivity of antimony hinder the practical application of Antimony based electrodes. A novel synthesis strategy for necklacelike biomass derived carbon fibers linked with MOF encapsulated Sb nanoparticles composite electrode is reported, wherein the unique structure of metal-organic frameworks (MOFs) is utilized to achieve nanoscale confinement and the inherent adsorption properties of fungi are exploited to construct conductive networks. The unique carbon encapsulation of MOF materials effectively controls the size of antimony particles and limits the expansion after potassization. The fixation of one-dimensional carbon fiber can prevent the powdering and shedding of the active materials and improve the cycle life of the composite electrodes. Electrochemical experiments and theoretical calculations show that NCFs@Sb@C anode has good conductivity and fast potassium ion diffusion kinetics. After 400 cycles at 1 A g −1 , NCFs@Sb@C still has a high reversible specific capacity of 129.3 mAh g −1 , which is significantly better than that of NCFs and Sb@C. In addition, the full cell of NCFs@Sb@C anode matched with PTCDA cathode exhibits good cycling stability, demonstrating the practical application potential of this composite electrode.

FeMn-HATP was synthesized as an efficient Sb(III) adsorbent. • Synergistic oxidative adsorption by FeMn-HATP enhances Sb(III) removal efficiency. • Kinetic, isotherm, and thermodynamic studies investigated FeMn-HATP adsorption. • An Sb(III) degradation mechanistic pathway is proposed. • FeMn-HATP demonstrated excellent regeneration performance in fixed-bed column tests. An affordable, environmentally friendly, simple adsorbent for Sb(III) removal from aqueous solutions was prepared using attapulgite (ATP) as the matrix, and FeSO 4 and KMnO 4 as metal precursors, through an in situ precipitation approach. The morphology, pore structure, and surface chemical properties of the material were analyzed using various characterization techniques. The results indicate that the iron-manganese bimetallic-modified acid-activated ATP (FeMn-HATP) surface is loaded with relatively uniformly distributed iron and manganese components, and its specific surface area and pore structure differ significantly from the original ATP. These changes promote pollutant molecule diffusion and contact. In batch adsorption experiments, FeMn-HATP achieved good Sb(III) removal performance and remained relatively stable within a pH range of 4 −10. The material maintained a relatively stable adsorption capacity even in the presence of high concentrations of other anions. Adsorption of Sb(III) by the modified ATP better conforms to both Elovich kinetic and Langmuir isotherm models, with a theoretical maximum adsorption capacity of 102.79 mg/g at 318.15 K. Fixed-bed cycling experiments demonstrated that FeMn-HATP retained significant adsorption capacity after five NaOH regenerations, with a dynamic adsorption capacity of 14.68 mg/g and a regeneration efficiency of 68.16%. Overall, FeMn-HATP exhibits good potential for Sb(III) removal with a degree of reusability, indicating promise for the treatment of antimony-containing wastewater.
