Sustainable and Greener Approach to the Synthesis of Magnesium Oxide Nanoparticles by Using Maize Leaf Biomediation: a Comprehensive Spectroscopic Characterization

Abstract

Green synthesis techniques have gained much attention, as they serve as an environmentally friendly substitute for the synthesis of nanoparticles. Here, we present a cheap, energy-efficient, and eco-friendly approach to producing magnesium oxide nanoparticles (MgONPs) utilizing maize leaves as a bio-reducing agent. This method reduces the effects of traditional chemical-based synthesis, by utilizing the reducing characteristics of maize leaves to promote the synthesis in a sustainable way. Using various analytical tools such as UV–visible, XRD, FE-SEM, and FTIR, we thoroughly characterized the synthesized nanoparticles. Biogenic MgONPs are of spherical morphology, and the size ranges from 40 to 100 nm, reflecting their multifunctionality. This work highlights the synthesis of maize-mediated MgONPs as a viable strategy for the environmentally friendly and sustainable synthesis of nanoparticles.
