Zusammenfassung:Zinc Oxide (ZnO) nanoparticles are photocatalyst materials with good dye photodegradation capabilities. ZnO nanoparticles also can decompose pollutants effectively, economically, and environmentally friendly. In this research, the wet grinding method and sol-gel method were used to synthesize ZnO nanoparticles for remazol yellow degradation. Different methods were used to determine which method was more effective. X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Particle Size Analyzer (PSA) characterization were carried out to determine the characteristics of the material. The effectiveness degradation of remazol yellow was confirmed by UV-Vis spectroscopy characterization. The XRD results showed that ZnO nanoparticles were successfully synthesized in both methods. The XRD results also showed that the material produced was in a crystalline phase with a high purity, yet the crystallite’s average size in the wet grinding method was 1.21 nm compared to the sol-gel method was 24.9 nm. The results of SEM and PSA characterization showed that the morphology of ZnO nanoparticles from both methods were spherical with an average particle size were 69 nm (wet grinding) and 99.9 nm (sol-gel). Then based on UV-Vis characterization results, the best photodegradation properties were shown by ZnO nanoparticles synthesized by wet grinding method. This is based on the degradation value of remazol yellow reaching 84.9% and compared to the sol-gel method which only reached 74.8%.
