Eco-friendly Synthesis of Zinc Oxide Nanoparticles Using Camellia sinensis (Green Tea) and Its Characterization

Nanoparticles can be synthesized in a simple and eco-friendly way without any toxic byproducts through process known as green synthesis. Green tea is great source of polyphenols flavonoids which used to synthesize ZnO nanoparticles. These nanoparticles have potential applications various industries medicine. tea's phenolic compounds act efficient reducers metal ions, stabilizes the growth The study using leaves then characterized them instruments. average particle diameter particles was 168.8 nm, they had zeta 38.2 mV. UV-Vis analysis showed blue-shifted absorption maximum at 323 indicating that were on nano-scale. XRD spectra calcined prominent diffraction peaks angles. Thermal stability confirmed by thermogravimetric analysis, revealed degraded rapidly 657°C, weight loss began 753°C.
