Synthesis and characterization of Zinc oxide nanoparticles

In this study, Zinc Oxide (ZnO) nanoparticles were synthesized using two distinct methods, with the goal of evaluating their structural and morphological properties. The particle size of the ZnO nanoparticles was determined using a particle size analyzer, yielding sizes of 320 nm and 559 nm for Sample No. 1 and Sample No. 2, respectively. The crystallographic analysis was performed using X-ray Diffraction (XRD), and the particle sizes were further corroborated by applying the Scherrer’s formula to the XRD peaks, which supported the particle size measurements obtained from the analyzer. The XRD results also indicated that both samples contained relatively low levels of impurities, confirming the high purity of the synthesized ZnO nanoparticles. Further examination of the morphological characteristics was carried out through Scanning Electron Microscopy (SEM). Agglomeration was observed in Sample No. 1, as revealed by the SEM micrographs, suggesting that particle aggregation occurred during the synthesis process. In contrast, Sample No. 2 displayed a uniform morphology with no visible signs of agglomeration, indicating better dispersion and stability of the nanoparticles in this sample. These findings suggest that the synthesis method plays a significant role in controlling the particle size distribution and the extent of agglomeration, which in turn affects the overall properties of ZnO nanoparticles. The study provides insights into the optimization of ZnO nanoparticle synthesis for various applications, where both particle size and agglomeration behavior are critical factors.
