The particle size of the S-NPs can be adjusted between 35 and 65nm by varying parameters such as the initial concentration of thiosulfate. The solvent/non-solvent precipitation method was also applied to the preparation of S-NPs for comparison. In this case, the use of hot alcohol and cold water as solvent/non-solvent system along with 100ml·min−1 flow rate for co-mixing of non-solvent resulted in the formation of S-NPs in a typical size of 250nm that are fairly homogeneous in shape and have a narrow particle size distribution. The results revealed that, in comparison to the precipitation process, the electro-synthetic method offers simplicity, higher efficiency, improved size control, and less environmental contamination. Figure Sulfur nanoparticles were prepared via electrochemical synthesis. Particle size of product was tuned by adjusting initial concentration of sodium thiosulfate in electrolyte solution. Meanwhile, the solvent/non-solvent procedure was also used to micronization of sulfur. Under optimum conditions, particles in submicron sized, homogeneous in shape with a narrow particle size distribution were formed.
