Green synthesis of titanium dioxide nanoparticles using Cassia fistula and its antibacterial activity
Green synthesis of titanium oxide nanoparticles has more advantages when compared with the chemical method. This work reports a green synthesis of titanium dioxide nanoparticles (TiO2NPs) by the herbal plant extracts of Cassia fistula. Then the green synthesized NPs were characterized by UV-Vis spectroscopy, X-ray Diffraction (XRD), Fourier transforms infra-Red spectroscopy (FT-IR), atomic force microscopy (AFM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA). The result of the SEM image shows that the nanoparticles are spherical in shape. The antibacterial activity was done on Escherichia coli and Staphylococcus aureus.
