Characterizations the PbS Nanoparticles Prepared by Plasma Induced Chemical Reaction

The research target explores how the bursting current and sodium sulfate (Na2S) concentration affect the structural and morphological properties of lead sulfide (PbS) nanoparticles. Three currents of 50, 60, and 70 A were run via a 0.5 mm-diameter lead wire. By dissolving 1, 0.75, 0.5 g of the sodium sulfate in 100 ml of water, 3 concentrations of sodium sulfate salt 10, 7.5, and 5 mg/cm3 were obtained. The sulfur ions react with lead ions when the wire explodes, producing PbS nanoparticles. X-ray diffraction analysis (XRD) of the particle structure revealed a face centered cube arrangement (fcc). The nanoparticles' size and form were detected utilizing a scanning electron microscope (SEM). SEM images showed that the PbS nanoparticle is spherical and that there is a correlation between the current and the size of the nanoparticles. The average particle size was measured at 30, 24, and 36 nm at currents of 50, 60, and 70 A, respectively. The variation in lead sulfate concentration slightly impacted the morphology and dimensions of the particles. This enables us to deduce the viability of creating lead sulfate nanoparticles in an easy, cost-effective, high-purity, and environmentally friendly technique.
