Abstract

Abstract: Green synthesis of nano materials has gained a great attention of current researchers owing to its less toxicity, reproducibility, pollution free, economic and low energy process. Green synthesis of Titanium dioxide (TiO2 ) nanoparticle was carried out using four different leaf extracts. The leaf extracts of Piper betel, Ocimum tenuiflorum, Moringa oleifera, Coriandrum sativum were used as reducing agents to synthesize TiO2 from Titanium tetraisopropoxide. The synthesized TiO2 nanoparticle was then characterized by X-Ray Diffraction (XRD), Fourier Transform-Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) techniques. The spectroscopic and microscopic techniques confirmed the formation, size and shape of the TiO2 nano particle. Further the differences in physical and morphological characteristics of synthesized nanoparticle incurred with the different with the usage of different leaf extract was analyzed and justified. The differences in the photocatalytic efficiency of synthesized TiO2 nanoparticles were studied by degrading Malachite green dye. Out of the four dyenanomaterials used, TiO2 synthesized using Moringa oleifera leaf extract was found to have greater efficiency when compared to other three leaf extracts.
