This study included the synthesis in environmentally friendly nanotechnologies using the leaf extract of the plant Paraserianthes lophantha. This eco-friendly method is safe and non-toxic or harmful to the environment. The method is economical, easy to operate, and highly efficient, and the properties of the resulting compounds can be controlled, in this way the ZnO compound can be controlled with the same plant extract and by the reaction. The research also included the result and study of the properties of these nanoparticles through various techniques including Field emission-scanning electron microscopic (FE-SEM) X-ray diffraction XRD. atomic force microscopy(AFM).Transmission electron microscopic studies (TEM). Also, the analysis of ZnO NPs was investigated by EDX-mapping and confirmed the existence and efficient degradation of Zn, O in the composite. The efficacy study of the prepared compound using bacteria was used. The activity of ZnO NPs and their effect on antibacterial was studied using two different types of bacteria, Gram negative E. Coli and Gram positive S.aureus e. Also, the photocatalytic ability of ZnO NPs was identified through the photodegradation process of the dyes, as the rhodamine B dye was degraded, and the rate of degradation was 83%.

The leaf extract of the plant Primo Fiore was used in this study to synthesize environmentally-friendly nanotechnologies. This eco-friendly method is non-toxic and does not hurt the environment. The approach is cost-effective, simple to use, and extremely efficient, with the ability to adjust the properties of the resultant compounds. For example, the ZnO compound can be controlled using the same plant extract and reaction. The impact of calcination temperature on the physical properties of ZnO NPs has been studied. X-ray diffraction (XRD) and energy dispersive spectroscopy were used to determine the structural and chemical composition of ZnO NPs (EDX). Field emission scanning electron microscopy (FESEM) and transmission electron microscopy were used to examine the morphological features of produced nanoparticles (TEM). The existence of functional groups was investigated using Fourier transform infrared spectroscopy (FTIR), according to the FESEM pictures. Most of the nanoparticles are on the nanoscale. This study demonstrated the efficacy of zinc oxide in the treatment of wastewater pollution for the degradation of colors in organic contaminants in the water medium, destroying the dye rhodamine B and its antibacterial properties.
