Abstract

The present study aims to extract and utilize the polyphenols of Camellia
sinensis and Mentha spicata as active capping agents for the bio-fabrication of
iron oxide nanoparticles (FeO NPs). Different techniques such as UV-Vis
spectroscopy, FTIR spectroscopy, XRD analysis, FESEM, EDX analysis, and
TGA were performed to determine the surface resonance, functional groups,
size, shape, elemental composition, and thermal stability of the polyphenol�mediated FeO NPs. UV-Vis spectrum of C. sinensis and M. spicata polyphenol�mediated FeO NPs revealed significant absorption at 230 and 250 nm, indi�cating the formation of FeO NPs. The presence of metal oxides in the FeO NPs
were verified through FTIR analysis. XRD spectra confirmed the crystalline
structure of C. sinensis and M. spicata polyphenol-mediated FeO NPs. The
occurrence of iron and oxygen was verified by the EDX spectra of both
polyphenol-mediated FeO NPs. TGA analysis established that C. sinensis
polyphenol-mediated FeO NPs had higher thermal stability than M. spicata
polyphenol-mediated FeO NPs.
