| Summary: | ZnO nanoparticles can be used as a photocatalyst in waste treatment because they have good photodegradation. Synthesis of ZnO nanoparticles using green synthesis method from pineapple peel extract, whose results were characterized by XRD (Xray Diffraction), FTIR (Fourier Transform Infra-red), FESEM (Field Emission-Scanning Electron Microscopy), TEM (Transmission Electron Microscopy), Raman spectroscopy, photoluminescence, and a photocatalytic activity assay. This research showed that ZnO nanoparticles had wurtzite phase, alcohol functional groups, and phenol O-H, C=C alkenes, C-O, C-N, and Zn-O. ZnO nanoparticles had a particle size of 20.04 nm, a spherical shape, and a band gap energy of 3.28 eV. The Raman active mode E2(High) at 439.05 cm-1 confirmed the formation of pure phase wurtzite. Photoluminescence results indicated that two emission peaks at 392.07 nm and 595.07 nm were associated with defects such as oxygen and zinc vacancies. The results of the photocatalytic effectiveness test showed the highest percent degradation value of 99.86% at 180 minutes using UV light. |
