“…In previous reports, two different reaction mechanisms were proposed for the galvanic replacement reaction between bulk Cu and Sb 3+ , , as shown below: The main points of debate are (i) whether the Cu is oxidized to Cu + or Cu 2+ and (ii) the main reaction product is Sb or Cu 2 Sb. To answer the first question, UV–vis absorption spectra were collected, and EPR measurements were performed.…”

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 Cu 2 Sb-mediated growth strategy to controllably fabricate highly uniform Sb nanotubes (NTs), as well as Cu@Cu 2 Sb and Cu 2 Sb@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 Na 3 (VOPO 4 ) 2 F 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.

“…Uniform colloidal NPs and NCs represent a very convenient platform for ex situ or in situ electrochemical studies, ranging from macroscopic electrodes in conventional half-cells to in situ electron microscopy imaging of a single particle during lithiation/delithiation. , In the form of uniform NPs, Sb has so far remained underexplored due to very limited control over the size and the shape achieved so far. ,− In this work, 10–20 nm Sb NCs with narrow size distributions of 7–11% (Figure ; for details see Supporting Information, including Tables S1–S6 and Figures S1–S10) were obtained by injecting Sb precursor into a hot (150–200 °C) solution containing a mixture of trioctylphosphine (TOP), lithium diisopropylamide (LiN(iPr) 2 , LiDPA), and oleylamine (OLA, or OleylNH 2 ). Two precursors, tris(dimethylamino)antimony(III) [Sb(NMe 2 ) 3 , or Sb(DMA) 3 ] and inexpensive antimony(III) chloride, yielded NCs of very similar quality under same reaction conditions.…”

Monodisperse Antimony Nanocrystals for High-Rate Li-ion and Na-ion Battery Anodes: Nano versus Bulk

et al. 2014

We report colloidal synthesis of antimony (Sb) nanocrystals with mean size tunable in the 10-20 nm range and with narrow size distributions of 7-11%. In comparison to microcrystalline Sb, 10 and 20 nm Sb nanocrystals exhibit enhanced rate-capability and higher cycling stability as anode materials in rechargeable Li-ion and Na-ion batteries. All three particle sizes of Sb possess high and similar Li-ion and Na-ion charge storage capacities of 580-640 mAh g(-1) at moderate charging/discharging current densities of 0.5-1C (1C-rate is 660 mA g(-1)). At all C-rates (0.5-20C, e.g. current densities of 0.33-13.2 Ag(1-)), capacities of 20 nm Sb particles are systematically better than for both 10 nm and bulk Sb. At 20C-rates, retention of charge storage capacities by 10 and 20 nm Sb nanocrystals can reach 78-85% of the low-rate value, indicating that rate capability of Sb nanostructures can be comparable to the best Li-ion intercalation anodes and is so far unprecedented for Na-ion storage.

Antimony is a promising material for the fabrication of photodetectors. This study deals with the growth of a photosensitive thin film by the physical vapor deposition (PVD) of antimony onto mica surface in a furnace tube. The geometry of the grown structures was studied via scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX) and elemental diffraction analysis. XRD peaks of the antimony film grown on mica mostly matched with JCPDF Card. The formation of rhombohedral crystal structures in the film was further confirmed by SEM micrographs and chemical composition analysis. The Hall measurements revealed good electrical conductivity of the film with bulk carrier concentration of the order of 10 22 Ω·cm −3 and mobility of 9.034 cm 2 /Vs. The grown film was successfully tested for radiation detection. The photoresponse of the film was evaluated using its current-voltage characteristics. These investigations revealed that the photosensitivity of the antimony film was 20 times higher than that of crystalline germanium.
