Technological advancement nowadays is detrimental to the environment. To deal with such a problem, waste decomposition should be carried out to produce a clean and healthy environment. In this study, the photodegradation method was used because it has advantages in efficiency and stability. The material used as a photodegradation catalyst was Fe 3 O 4 @ZnO nanoflowers. The synthesis of Fe 3 O 4 @ZnO nanoflowers was carried out using coprecipitation method for Fe 3 O 4 and precipitation for composites. The variations in the mass of the catalyst used in this study were 50, 100, and 150 mg. The samples were characterized using an X-Ray Diffractometer (XRD) to analyze the phase, size, and crystal structure, Scanning Electron Microscopy (SEM) to determine morphology, and a photodegradation test to measure the photodegradation activity. The grain sizes of Fe 3 O 4 and ZnO nanoflowers based on the Scherrer equation were 12.12 nm and 32.29 nm, respectively. Based on SEM characterization, the morphology of Fe 3 O 4 @ZnO nanoflowers showed a flower-like structure with an average diameter of 3.2 µm. The best performance of phenol photodegradation activity is 54.3 % obtained in the first cycle of 150 mg Fe 3 O 4 @ZnO nanoflowers under solar irradiation.
