Synthesis and Preparation of Antimony Tin Oxide Nanoparticle

Considering the predominant applications of antimony tin oxide nanoparticles, numerous methods and techniques have been introduced to obtain them. It has to be taken into consideration that the properties of ATO are influenced by the synthesis and preparation process. The goal is always to obtain crystals with controlled size and an appropriate monodispersity to achieve high-performance material. On the contrary, synthesizing antimony tin oxide nanoparticles is still challenging, combining all the required standards and determining factors like adequate conductivity, desirable particle size crystallinity, narrow particle size distribution, and favorable dispersibility in a particular solvent. The most common and known methods include simple thermal evaporation, microemulsions, sol-gel, hydrothermal methods, co-precipitation, mechanochemical, laser ablation, screen printing, combustion route, microwave-assisted synthesis, thermal decomposition, hot injection, and DC arc plasma jet synthesis. In a different method, antimony tin oxide nanoparticles are synthesized via dissolving granulated tin (Sn) in nitric acid (HNO­3). Separately, Antimony trioxide (Sb2O3) is dissolved in melted citric acid, added to the previous solution, and stirred for 3 hours at room temperature. After that, antimony hydroxide is added to the solution to process the precipitation of Sb3+ and Sn4+ metal ions, and the pH of the solution is adjusted to 7. The hydroxide precipitate is washed in double distilled water until the color of the samples turns yellow. The resulting precipitates are dried at 100°C for 4 hours and calcined at 600°C for 2 hours in a muffle furnace to ensure the particle's conductive properties 3. Several studies have focused on the assembly of antimony tin oxide nanoparticles into aerogels as big as a few centimeters with increasing applications as catalysis, photocatalysis, and ferroelectric agents with promising properties like high porosity, high surface area to low density magnetic and optical quality. The assembly procedure is carried out by microwave heating and the assistance of a non-aqueous sol-gel reaction of antimony acetate Sb(CH3COO)3 with tin chloride (SnCl2) in the solvent made by mixing benzyl alcohol and toluene. The mixture is heated to 150°C for 9 minutes to obtain a brown precipitate 4.
