“…The S 2p peak was observed near 161.50 eV. The peak positions of Sb and S were similar to those reported in the existing literature [30][31][32][33], indicating that the phase representing the volatile was Sb2S3. The high-resolution XPS spectrum of S 2p is presented in Figure 10a, and the S 2p peak was observed near 160.90 eV.…”

Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were analyzed by the Clausius–Clapeyron equation. Moreover, the volatilization behavior of antimony sulfide and the enrichment law of gold were studied by heat volatilization experiments. The effects of the sulfide temperature and volatilization pressure on the separation efficiency of antimony and gold enrichment were investigated. The results demonstrate that the sulfuration rate was the highest, namely 96.06%, when the molar ratio of sulfur to antimony was 3:1, the sulfur source temperature was 400 °C, the antimony source temperature was 550 °C, and the sulfuration time was 30 min. Antimony sulfide prepared under these conditions was volatilized at 800 °C over 2 h at an evaporation pressure of 0.2 atm, and the volatilization rate was the highest, namely 92.81%. Antimony sulfide with a stibnite structure obtained from the sulfuration–volatilization treatment of electrodeposited antimony meets the ideal stoichiometric ratio of sulfur and antimony in Sb2S3 (3:2), and gold is enriched in the residue.

“…The Cu substrate has a terrace pattern and the terrace sites will serve as the nucleation center for the Sb deposit. Additionally, the interplay between nucleation and growth of Sb would be influenced by citric acid . Citric acid molecules will chelate Sb 3+ ions to form a complex structure, which slowly releases Sb 3+ ions enabling a homogenous growth .…”

Antimony (Sb) is a promising anode material for sodium‐ion batteries owing to its large capacity of 660 mAh g−1. However, its practical application is restricted by the rapid capacity decay resulted from a large volume expansion up to 390% upon Na alloying. Herein, construction of a self‐supported Sb array that has enough space allowing for effective accommodation of the volume change is reported. The array of Sb prisms is directly grown on a Cu substrate via a template‐free electrodeposition, followed by mild heating to consolidate the structural integrity between Sb and Cu. The resulting 3D architecture endows the Sb array with excellent sodium storage performance, exhibiting a reversible capacity of 578 mAh g−1 and retaining 531 mAh g−1 over 100 cycles at 0.5 C. The potential of Sb array in sodium‐ion full cells by pairing it with a Na0.67(Ni0.23Mg0.1Mn0.67)O2 cathode is further demonstrated. This full cell affords a specific energy of 197 Wh kg−1 at 0.2 C and a specific power of 1280 W kg−1 at 5 C. Considering its low cost and scale‐up capability, the template‐free route may find extensive applications in designing electrode architectures.
