Green synthesis of zinc oxide nano-sized spherical particles using Terminalia chebula fruits extract for their photocatalytic

The present study describes the green synthesis of ZnO nano-sized spherical particles (ZnO-NPs) using aqueous fruits extract of Terminalia chebula. The Structural, morphological and optical properties of green-synthesized ZnO-NPs are characterized by X-ray diffraction, Fourier transform infrared, field emission-scanning electron microscope, ultraviolet–visible and photoluminescence spectroscopy techniques. The results show that the synthesized nanoparticles have stable hexagonal wurtzite structure, and roughly spherical in shape. To explore the photocatalytic activity of the ZnO-NPs the photocatalytic degradation of rhodamine B (RhB) dye is investigated. The results reveal that ZnO-NPs prepared through green synthesis route are found to be efficient in the degradation of RhB dye.
