The green synthesis of titanium dioxide (TiO2) nanoparticles using Psidium guajava (guava) leaves has gained significant attention due to its eco-friendly approach and cost-effectiveness. In this study, TiO2 nanoparticles were synthesized by reducing titanium precursor (titanium tetrachloride) in the presence of aqueous extracts of Psidium guajava leaves. The phytochemical components of the leaf extract, such as polyphenols, flavonoids, and organic acids, act as reducing agents and stabilizers during the synthesis process. The resulting TiO2 nanoparticles were characterized using various techniques, including UV-Visible spectroscopy, X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), and Fourier-Transform Infrared (FTIR) spectroscopy. This green synthesis approach provides a sustainable alternative to traditional methods, offering a low-cost and environmentally benign route for the production of TiO2 nanoparticles.
