Morphological and photocatalytic properties of zinc oxide nanoparticles synthesized from agricultural wastes of Nephelium lappaceum L. and Garcinia mangostan L.

Abstract

A facile, innovative and ecofriendly approach of biofabrication of zinc oxide nanoparticles (ZnO–NPs) using agricultural wastes (seed and peel) of Nephelium lappaceum L. and Garcinia mangostana L. have been demonstrated in this study. Characterizations of ZnONPs were carried out using Ultraviolet-Visible (UVvis) spectrophotometry, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive spectroscopy (EDX), and Fourier Transform Infrared spectroscopy (FTIR). The formation of ZnO-NPs was preliminary confirmed by the UV–vis spectroscopy, by the appearance of peaks between 362368 nm.
