Efficient Green Synthesis of TiO2 Nanoparticles Using Murrayakoenigii Leaf Extract

Navinchandra G. Shimpi, Satyendra Mishra, Sharada D. Shirole


Green synthesis of nanoparticles by plant extract is at present under exploitation due to eco-friendly, non-toxic and inexpensive process. Titanium dioxide (TiO2) nanoparticles were synthesized by ultrasound assisted sol-gel precipitation method using titanium tetra-isopropoxide as a precursor and Murrayakoenigii leaf extract as a reducing and stabilizing agent. The leaf extract was prepared under various solvent media such as ethanol and distilled water under controlled ultrasonication. Due to effective ultrasound, the extraction of chemical agents from Murrayakoenigii leaf was in a large extent. The effect of various leaf extracts on size of TiO2 nanoparticles was studied using transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and photoluminescence spectroscopy (PL). The nanoparticles prepared from ethanolic leaf extract were found to be smaller and spherical in shape (~2–15 nm) as compared to leaf extract prepared using water (~15–30 nm). Besides this, X-ray diffraction (XRD) study shows TiO2 of anatase form. Moreover, the band gap values of TiO2 nanoparticles were found to be 3.26 and 3.17 eV for ethanolic and water leaf extracts, respectively studied from PL spectra. The FT-IR spectra of TiO2 nanoparticles exhibit a prominent peak at 714 (Ti-O-Ti bond), 1642 (N-H) (O-H stretching).
