ZnO nanoparticles have been synthesized using Terminalia catappa leaf extract and their characteristics. The properties of ZnO nanoparticles were characterized by UV-Vis spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The highest absorbance peak is in the ultraviolet region, which is in the wavelength range of 300-350 nm. The hexagonal wurtzite crystal structure of ZnO has been confirmed by XRD analysis with the highest reflection peak at a reflection angle of 2θ = 36.26°, with a crystal plane (101). SEM characterization showed the presence of nano-flower morphology with a size distribution of 400-494 nm. The results of this study show that ZnO nanoparticles can be applied as photocatalysts for the degradation of methylene blue.
