Abstract
Abstract
This research aims to synthesize zinc oxide nanoparticles using Terminalia catappa leaf extract. The synthesis method used Terminalia catappa leaves as a reductor. Synthesized ZnO nanoparticles were characterized using UV-vis, XRD, SEM, and TEM. UV-vis spectroscopy of samples showed peak absorption in the 300-380 nm range. The results of XRD characterization show that the ZnO nanoparticles crystal structure is hexagonal wurtzite, where the highest peak of reflection occurs at the reflection angle 2θ=36.24 of the crystal plan (101). SEM characterization results refer to flower-shaped morphology with a size distribution between 392-423 nm. These findings reveal morphology insight into the photocatalytic of ZnO nano-flowers for the environment.
