Low cost synthesis of ZnO nanoparticles and evaluation of their photocatalytic activity

A series of ZnO nanoparticles were synthesized by a biosynthesis method. The as-obtained products were characterized with powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Photoluminescence (PL) and Raman spectra. The ZnO nanoparticle exhibited superior photocatalytic activities for indigo carmine degradation under visible light irradiation. In addition, the photocatalyst exhibits high stability and reusability. (C) 2019 Elsevier Ltd. All rights reserved.
