Abstract
The present study revealed the synthesis of zinc oxide nanoparticles by wet chemical co-precipitation process and were characterized by X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), UV-Vis spectroscopy, and photocatalysis for Methylene Blue (MB) dye degradation. The crystallite size of the ZnO nanoparticles calculated from XRD using Debye Scherrer Formula is 36.27 nm. The size variation of the ZnO nanoparticles is due to the difference in annealing temperature and precursors. The FTIR spectra confirms the formation of ZnO nanoparticle. From UV-Vis spectra of ZnO nanoparticles, the absorption peak is at 380 nm and decreases with time which shows the dye degradation. MB dye degradation efficiency by ZnO nanoparticle is 91.78% in 21 minutes.
