Size selective synthesis of tetraoctylammonium bromide stabilized-nonstabilized sulfur nanoparticles

الملخص EN

Sulfur nanoparticles (S NPs) were prepared by a quick precipitation method in the absence and presence of tetraoctylammonium bromide (TOAB) that was used as a stabilizer to control the nanoparticles size.

Scanning electron microscope (SEM), transmission electron microscope (TEM) and X-Ray Diffraction (XRD) were used to characterize the obtained S NPs.

The average size of S NPs was in the range 2.4 – 8.9 nm, with spherical like shape.

The NPs size was controlled by changing the preparation parameters: temperatures, different acid concentrations, different acid types and the presence of TOAB stabilizer.
