Synthesis of titanium dioxide nanoparticles using Spirulina platensis algae extract

Abstract

An investigation of green synthesis of titanium dioxide nanoparticles using Spirulina platensis algae extract was undertaken in the Department of Sericulture, Forest College and Research Institute, Mettupalayam. The nanoparticles formation, particle size, exterior morphology and shape of synthesized TiO2 NPs were analyzed through UV-Vis absorbance spectroscopy, X-Ray diffraction and Scanning electron microscope (SEM) respectively. The results showed that the absorbance spectra of synthesized NPs were observed at 300nm. X-Ray diffraction analysis revealed that the formation of good crystalline TiO2 NPs with anatase phase. The synthesised NPs were in spherical shape and dispersed irregularly. The green synthesised of TiO2 NPs is a simple approach, inexpensive and eco-friendly process which having potential applications in various fields.
