Hexahydroxoantimonate for the Synthesis of Antimony-Doped Tin Oxide-Based Coatings
Sladkevich, Sergey, et al. Inorganic chemistry 49.20 (2010): 9110-9112.
A novel method for applying conductive film coatings of minerals and acid-sensitive materials with antimony-doped tin oxide (ATO) has been developed. The coating process involves using a precursor solution of stannate and antimonate stabilized with hydrogen peroxide. The method successfully produced uniform coatings on various clays and irregular shapes using monosized 5 nm ATO particles. The deposition mechanism is clarified through a hydrogen peroxide capping process and the formation of hydrogen bonds between hydroperoxo nanoparticles and H2O2-activated mineral surfaces, which favor mineral surface coating over the uniform agglomeration of tin oxide particles.
Preparation Details
The precursor solution is created by combining aqueous tetramethylammonium hexahydroxostannate and hexahydroxoantimonate solutions. The addition of 15% hydrogen peroxide keeps the solution translucent. ATO coating is achieved by immersing the substrates in this H2O2 precursor solution and adding excess ethanol. The resultant coated material is then filtered or centrifuged, washed with ethanol, and calcined. The coated material at room temperature retains a few percent of active oxygen and some organic residues, which are eliminated during heat treatment. Omitting the hydrogen peroxide in this process leads to the formation of ATO agglomerates instead of a thin film coating.
Conversion/Dissolution Research of Antimony Compounds Such as Sodium Hexahydroxoantimonate
Skeaff, James M., et al. Integrated environmental assessment and management 9.1 (2013): 98-113.
This work has applied the OECD transformation/dissolution (T/D) Protocol (UN 2011) to examine the T/D behavior of NaSb(OH)6 (Sodium Hexahydroxoantimonate), Sb metal, Sb2O3, Sb2S3, NaSbO3, Sb2(C2H4O2)3, SbCl3, Sb(CH3COO)3, and Sb2O5 at pH 6 and 8.5.
Key Findings
· Due to complexation, the trivalent organic antimony compounds showed minimal oxidation of Sb(III) to Sb(V), while the trivalent inorganic antimony compounds demonstrated clear oxidation of Sb(III) to Sb(V). In contrast, the pentavalent antimony compounds did not reduce Sb(V) to Sb(III).
· At a loading of 1 mg/L over 28 days, NaSb(OH)6 demonstrated the highest solubility, completely dissolving at both pH levels. Following this, Sb(CH3COO)3 dissolved 81% under the same conditions. Sb metal showed reactivity with 57% dissolution at pH 6 and 61% at pH 8.5. Next, Sb2(C2H4O2)3 exhibited 27% solubility at pH 6 and 56% at pH 8.5, while SbCl3 and Sb2O3 recorded 31% and 21% dissolution, respectively, at pH 8.5.
· Therefore, in order of decreasing dissolution percentage at pH 6, the hierarchy is: NaSb(OH)6 > Sb(CH3COO)3 > Sb metal > Sb2(C2H4O2)3 > Sb2S3 > Sb2O3 > NaSbO3 > SbCl3 > Sb2O5. For pH 8.5, it follows this order: NaSb(OH)6 > Sb(CH3COO)3 > Sb metal > Sb2(C2H4O2)3 > SbCl3 > Sb2O3 > Sb2S3 > NaSbO3 > Sb2O5. Only NaSb(OH)6 exhibited complete solubility with rapid 100% dissolution.
