Studies on the Electrochemical Preparation of Sb₂O₃

Abstract

The electrochemical preparation of antimony trioxide (Sb2O3) employing an antimony anode and a stainless steel cathode is described. The effects of different electrolytes, electrolyte concentration, pH, temperature, anode current density, different cathode materials, and different additives on current efficiency and purity for the preparation of antimony trioxide were studied. A maximum current efficiency of 99.2% was achieved corresponding to the energy consumption of 1.26 kWh·kg-1.

Phase and morphology controllable synthesis of Sb2O3 microcrystals

“…For Sb 2 O 3 nanomaterials, most efforts have been focused on the synthesis of onedimensional nanocrystals, such as Sb 2 O 3 nanorods, nanowires, nanobelts, and nanotubes [4][5][6][7]. Electrochemical preparation of Sb 2 O 3 was carried out by employing an antimony anode and a stainless steel cathode [8]. Sb 2 O 3 thin films have been prepared by a low energy cluster beam deposition technique [9].…”

Facile catalyst-free straightforward thermal evaporation of ultra-long antimony oxide microwires: Synthesis and characterization

“…Various low temperature methods have been used for the synthesis of antimony oxides micro/nano nanostructures, such as microemulsion, hydrolysis-precipitation approach, solvothermal, hydrothermal aqueous strategy electrochemical and biosynthesis methods, respectively [6][7][8][9][10][11][12][13][14][15][16][17]. Also high temperature vapor condensation and carbothermal reduction have been reported [18,19].…”
