Zinc oxide plays an important role in the current industry due to its special characteristics such as anti-corrosion, anti-bacteria, low electron conductivity and excellent heat resistance. The synthesis of Zno NPs by the sol-gel method has recently gained widespread use to synthesize and characterize zinc oxide nanoparticles. Sol-gel method is the simplest method and has the ability to control the particle size and morphology through systematic monitoring of reaction parameters. ZnO nanoparticles were synthesized via sol-gel method using Zinc acetate dehydrate (Zn(CH 3COO) 2.2H 2O) as a precursor and ethanol (CH 2COOH) were used as a solvent, Sodium hydroxide (NaOH) and distilled water were used as a medium. ZnO nanoparticles were characterized by using XRD, EDX, FESEM, and nano-particles analyser. The result of EDX characterization shows that the ZnO nanoparticles have good purity with (Zinc content of- 55.38% and; Oxygen content of- 44.62%). XRD result spectrum displays mainly oxygen and zinc peaks, which indicate the crystallinity in nature as exhibited. FESEM micrographs show that synthesized ZnO have a rod-like structure. The obtained ZnO nanoparticles are homogenous and consistent in size which corresponds to the XRD result that exhibits good crystalline. ZnO nanoparticles were successfully synthesized by the sol-gel method in the nano size range between 81.28 nm to 84.98 nm.
