Eco-friendly green synthesis of metal oxide nanoparticles prepared from different leaf extracts

Ecologically benign reactants and green synthesis of metal oxide nanoparticles are receiving a lot of attention. This is the most popular way of preparation since it uses chemicals that do not contribute to pollution and promotes the use of non-toxic solvents like water and plant extracts. The goal of the current work is to create ZnO nanoparticles by an environmentally friendly, green process that uses leaf extract from environmentally safe plants like Azadirachta indica (Neem) and Acalypha indica where zinc nitrate serves as the precursor. The crystalline structure of the sample was revealed by X-ray diffraction (XRD) analysis and functional groups were identified using Fourier transmission infrared (FT-IR) spectroscopy. Energy dispersive spectroscopy (EDS) and Field emission scanning electron microscopy (FE-SEM) were used to evaluate the shape, structure and content.
