Abstract

In this study, pure ZnS nanoparticles are prepared using a simple co-precipitation method. X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray Analysis (EDAX), UV-visible spectroscopy, and photoluminescence studies were employed to evaluate the synthesized nanoparticles. UV-visible absorption spectrum issued to calculate the optical band gap energy, and its value is approximately 4.27 eV. On examining the XRD pattern, it depicts that the particle size of the nanoparticles is about 44 nm, their capacity to perform better across a range of applications. The EDAX analysis confirms that the synthesized nanoparticles are pure. The catalysis of MB dye by synthesized ZnS nanoparticles exhibits pseudo-first order kinetics with observed rate constants.
