Abstract

The research has been carried out on synthesizing zinc oxide (ZnO) nanoparticles with the help of microwaves. ZnO nanoparticles were synthesized in the microwave at 100°C with heating times of 50, 90, 130, 170, and 210 minutes. The synthesized ZnO nanoparticles were characterized using X-Ray Diffractometry (XRD) and Energy Dispersive Spectroscopy (EDS). The results were analyzed for their ability as a photocatalyst against methylene blue (MB) solution using UV-Vis spectrophotometry. The results revealed that the synthesized product was a combination of ZnO and Zn(OH) 2, as supported by XRD ICSD data no. 31052. However, the analysis results with EDS showed that the synthesized product only contained Zn and O elements, indicating that the product had ZnO. ZnO nanoparticles synthesized for 170 minutes of heating showed the highest ability to degrade MB of 85.8247% with a contact time of 150 minutes, while heating times of 50, 90, 130, and 210 minutes had percentage of MB degradation of 84.6065%, 81.0130%, 82.0866%, and 82.9275%, respectively.
