▎ 摘　　要

This study describes the synthesis of a reduced graphene oxide/zinc oxide (RGO/ZnO) hybrid nanocomposite using the green process of Prunus x yedoensis leaf extract and nanocomposites for the removal of phosphate from aqueous solutions. This leaf extract was a reducing agent and was calcined at 500 degrees C for 1 h. The RGO/ZnO nanocomposites' surface morphology and crystal structure were characterized by high-resolution transmission electron microscopy, scanning electron microscopy-energy dispersive spectroscopy, and X-ray powder diffraction. The functional groups were confirmed by Fourier transform infrared spectroscopy and Raman spectroscopy. The surface adsorption characteristics of nanocomposites for the degradation of phosphates were assessed at varying time intervals; phosphate removal via RGO/ZnO nanocomposites was also investigated.
