Green synthesis of titanium dioxide nanoparticles using Phyllanthus niruri leaf extract and study on its structural, optical and morphological properties

In this research non-toxic, cost-effective TiO₂ nanoparticles were prepared using Phyllanthus niruri leaf extract. The crystallinity and purity of green treated TiO₂ nanoparticles were investigated using X-ray diffraction (XRD) studies. The specific functional groups responsible for the reduction of TiO₂ nanoparticles were analyzed using Fourier transform infrared spectroscopy (FTIR). The formation of spherical shaped TiO₂ nanoparticles was confirmed using Transmission electron microscopy (TEM). The optical properties of green treated TiO₂ nanoparticles reveled through UV-Vis-Diffused reflectance spectroscopy (DRS). The obtained results show that the green treated TiO₂ nanoparticles can act as a better photocatalytic material.
